Detailed description of the invention

To 12, prior art ALFDEX is described now with reference to Fig. 1 of accompanying drawing?Separator, and emphasize to be placed on those aspects improved by the present inventor of the prior art separator especially。

At Fig. 1 of accompanying drawing, in 2,8,9 and 10, show the prior art ALFDEX assembled?Some views of separator 2。It will be understood by those skilled in the art that prior art separator 2 includes the rotor case 4 of general cylindrical, its for receive act as from be directed to described rotor case 4 releasing gas in separate some fuel-displaced internals。

One end of cylindrical housing 4 is provided with the annular shoulder 6 of setting, and it limits the fluid intake 8 of separator 2。It will be appreciated that therefore, release from crankshaft shell and need the gas therefrom removing oil to enter separator 2 by fluid intake 8。

Aperture 10 offer in the cylindrical wall of rotor case 4 is sent to the outlet of the other housing 12 being associated with valve cell 14 (see Fig. 1) for purifying gas from the inside of rotor case 4。Valve cell 14 includes arranging for the valve controlling the stream purifying gas from separator 2。The details of the operation of valve cell 14 will not be described herein as。But, as will become apparent to from Fig. 1, the outside of rotor case 4 is specifically designed to mate with the housing 12 of valve cell 14 so that two housings 4,12 combinations limit being applicable between described housing 4,12 and receive the inner space of the internals of valve cell 14。Two housings 4,12 are fixed to by traditional threaded fastener 16 to be gone up each other。It is therefore to be understood that specific valve cell housing 12 only can use together with having the concrete rotor case 4 of necessary mating feature。

With reference to Fig. 1, it will be seen that, the housing 12 of valve cell 14 is provided with the annular shoulder 18 of setting, and this shoulder 18 defines fluid issuing, purifies gas and is sent out from separator 2 by this fluid issuing。The annular shoulder 18 provided on valve cell housing 12 is essentially identical with the annular shoulder 6 of offer on rotor case 4。Owing to their similarity, entrance shoulder 6 and outlet shoulder 18 can receive the inlet/outlet pipe joint with identical interface profile interchangeably。One with 90 ° of elbows this pipe joint 22 is shown in figure 3 with cross section。One end of pipe joint 22 is provided with the circumferential collar 24 defining annular recess 26。Annular recess 26 has such square edge profile and diameter, and this square edge profile and diameter allow it to receive casing annular shoulder 6,18 (this shoulder also has square edge) (in the way of being adjacent)。

Fig. 2 that the shoulder 6 of rotor case 4 can refer to accompanying drawing with the joint of inlet pipe joint 28 finds out。It will be appreciated that the pipe joint 28 shown in Fig. 2 has the bent angle that the pipe joint 22 from Fig. 3 is different。

Inlet/outlet pipe joint holds them at Housing shoulder 6 by using ring washer 30, their corresponding housing 4,12 it is fixed to, when the threaded lobe 34 of threaded fastener 32 and two is threadably engaged on 18, packing ring 30 is downwardly against on the shoulder 24 of pipe joint 22,28。Two lobe 34 are erect from relevant housing 4,12 and are positioned on the both sides of annular shoulder 6,18。O-ring packing 36 is positioned at, catches and is compressed between recess 26 and Housing shoulder 6,18, in order to prevent fluid from undesirably leaking from the interface between inlet/outlet pipe joint with corresponding housing (seeing Fig. 2 about inlet pipe joint)。

With further reference to pipe joint 22 shown in Fig. 3 and 2 respectively, 28, second end (distant place, one end being provided with interface profile) of pipe joint is provided with tooth or sawtooth 38 on its outer surface, in order to grasping flexible pipe, this flexible pipe is positioned on pipe joint the second end in use。

The fluid flow path provided by two pipe joints 22,28 each includes the elbow with the basic interior turning 40 lacking radius。In prior art separator 2, angled pipe joint uses injection-molded (for joint for plastic tube) and die casting (for aluminium tube joint) technology manufacture。As will be will be readily understood that from Fig. 4 (which show the molding of pipe joint 22), in order to allow respectively by the first and second arrows 46, removing the first and second internal mode product sections 42,44 on the direction of 48 instructions, moulded parts sections 42,44 internally can not provide radius in turning 40。

To be more fully described the aforementioned inner component held by rotor case 4 referring specifically to Fig. 8 now。

First, top axle bearing unit 50 is fixed on the inner surface of rotor case 4 in the direct downstream of fluid intake 8。Top axle bearing unit 50 includes catching the cage bearing 52 between upper steel caps part 54 and the step parts 56 of plastic material。Bearing unit 50 manufactures by moulding step parts 56 around upper steel caps part 54, and wherein cage bearing 52 is securely maintained between them。The layout of top axle bearing unit 50 clearly illustrates in fig. 8, but they are also shown in Fig. 2 and 9 in the environment of prior art separator 2。

Bearing holder component 56 has round-shaped and downward projection of cylindrical wall 58 (low portion around cap member 54), and its cylindrical wall 60 abutting against rotor case 4 in the separator 2 assembled laterally adjoins。The correct lateral register that contribute to guarantee top axle bearing unit 50 relative to rotor case 4 adjacent with cylindrical wall 60。Second cylindrical wall 62 of rotor case 4 is radially positioned at the inner side of the first cylindrical wall 60, in order to guarantee the top axle bearing unit 50 correct axial location relative to rotor case 4。Top axle bearing unit 50 is fixed to rotor case 4 by means of three threaded securing member (not shown)s。The layout of separator 2 makes the rotation axis of top axle bearing unit 50 overlap with the central axis 64 of rotor case 4。

Three part circular grooves 66 (only show two of which in Fig. 8) are provided in top axle bearing unit 50, in order to allow inlet fluid flow to cross wherein (as shown in arrow 68)。Upper cap member 54 makes the entrance fluid deflector from cage bearing 52, but as will be understood by those skilled, the downside of the topmost part of cap member 54 also makes travel up through armature spindle during use and enter lubricating oil mist deflection (in cage bearing 52) of top axle bearing unit 50。

Remaining internals of separator 2 and rotor case 4 are assembled separately, and are then positioned in housing 4 as black box。Black box includes keeping the first fixing fabric part and the second fabric part rotated around central axis 64 relative to rotor case 4 (with valve cell housing 12) and the first fabric part when using separator 2 when using separator 2 relative to rotor case 4。

First fabric part includes the support plate 70 of annular shape and the parts 72 of the dish type being called housing insert。Housing insert 72 is combined with support plate 70 and acts as and isolated isolated oil and purified gas before leaving rotor case 4 at isolated oil and purification gas。Support plate 70 is formed from steel, and housing insert 72 is made up of plastic material。Support plate 70 and housing insert 72 are fixed to go up each other by means of three threaded fasteners 74 (showing only one therein in Fig. 1 of accompanying drawing), and threaded fastener 74 is threadedly engaged with the downward projection of lobe 76 in downside from housing insert 72。This first fabric part will be discussed in more detail subsequently in this specification。

Second fabric part formed rotor assembly and include rotating shaft 78, upper rotor part dish 80, collectively form separator disks 82 stacking 84 multiple independent separator disks 82, end plate 86, and combination fan and turbine unit 88。This component of second group according to so that the mode preventing them from relative to each other rotating is fixed to is gone up each other。But, the second fabric part is rotatably mounted to the first fabric part by means of bottom bearing unit 90 (seeing Figure 10 especially)。

The rotor assembly that by second fabric part formed be will be described in further detail now。

Rotating shaft 78 is made up of metal material, and has ring section, in order to provide the fluid flow path 92 extended longitudinally along its whole length。When using separator 2, this flow path 92 allows oil mist be passed up through rotating shaft from turbine shroud and be sent to top axle bearing unit 50, in order to lubricate the bearing of described unit 50。Annular disk (have and be radially therefrom the cylindrical wall that outer circumferential periphery is erect) flow restrictor element 93 of form be located at the described fluid flow path 92 of the upper end of rotating shaft 78 on upper interior shoulder。Flow restrictor element 93 acts as reducing the flow path area (thus providing nozzle) by rotating shaft 78 in the exit entering top axle bearing unit 50 from rotating shaft 78。

Rotating shaft 78 be provided externally with some recess and shoulders for receiving back-up ring, back-up ring contributes to the correct axial location being maintained at by component on rotating shaft 78。One this back-up ring 94 is clearly shown as the shoulder provided towards upper in figure 6, and packing ring 95 abuts against this back-up ring 94 and adjoins。Spiral compression spring 96 adjoin packing ring 95 towards upper shoulder。The peripheral recess that back-up ring 94 is located therein has enough width (that is, the size on the axial direction of recess), to allow back-up ring 94 to be axially moveable along rotating shaft 78 (in recess)。This allows spring 96 that axial force is applied to bottom bearing unit 90。

Other recess is provided on the outer surface of rotating shaft 78, for being positioned and retained in by component on described axle 78。

Each in upper rotor part dish 80, separator disks 82 and end plate 86 has frusto-conically shaped portion (defining fi-ustoconical surface 102), plurality of spoke parts extend radially inward into hub element from them, and this hub element is positioned at around rotating shaft 78 in use。

Although the spoke parts of upper rotor part dish 80 and separator disks 82 have unlimited space between which, to allow fluid to flow axially through them along rotating shaft 78, but the spoke parts of end plate 86 are attached at their lower surface place and go up each other, in order to prevent fluid along rotating shaft 78 or be upward through end plate 86 or be passed down through end plate 86 and flow vertically。

The Frusto-conical geometry of upper rotor part dish 80 and end plate 86 is essentially identical with the geometry of separator disks 82, to allow upper rotor part dish 80 and end plate 86 to be stacked with separator disks 82, wherein, upper rotor part dish 80 is positioned at the top place of separator disks stacking 84, and end plate 86 is positioned at the bottom place of separator disks stacking 84。Additionally, although skilled artisan will appreciate that separator disks 82 ratio is relatively thin, to allow large number of dish to be provided in relatively short stacking 84, but upper rotor part dish 80 and end plate 86 are much thicker than separator disks 82, to provide rigidity at the two ends place of dish stacking 84, and consequently allow for compression axial force and be evenly applied to the frusto-conically shaped portion of separator disks by upper dish 80 and end plate 86。Compression stress more specifically by be pressed up to end plate 86 hub 98 downside on spiral compression spring 96 produce。

About compact disk stacking 84 between upper dish 80 and end plate 86, skilled artisan will appreciate that, the adjacent separator disks 82 in stacking 84 must keep being spaced apart from each other, in order to allows fluid to flow through separator 2。This interval of separator disks 82 provides by means of the multiple ribs 100 (being called joint filling part) provided on the upper surface on the frusto-conically shaped portion of each separator disks 82。Each joint filling part 100 extends to the radially outer edge 106 on described surface from the inner radial edge 104 of described upper surface 102。Joint filling part 100 is erect from described upper surface 102 and is stretched out (standproudof), and in stacking the 84 of the separator disks 82 assembled, the downside of adjacent adjacent dish above。As the skilled person will appreciate, each separator disks 82 can be positioned on rotating shaft 78 relative in only six feasible Angle Position of rotating shaft 78, and the joint filling part that the location that joint filling part 100 is on described upper surface 102 makes adjacent dish 82 must be aligned with each other when dish 82 is arranged in any one in these six positions。As a result, end plate 86 it is applied in the inc situation in interval between adjacent separator disks 82 of the compression stress on dish stacking 84 by means of the joint filling part 100 of alignment and passes through stacking 84。

Further with regards to the compression stress being applied to separator disks stacking 84, skilled artisan will appreciate that, this power is produced and is applied to by spiral compression spring 96 on end plate hub 98。Due to the rigidity of end plate 86, compression stress is delivered to the frusto-conically shaped portion 108 of end plate 86 by multiple spokes 110 radially extended of end plate 86 from hub 98。Compression stress then passes through frusto-conically shaped portion 108 and is delivered to dish stacking 84, and is delivered to the frusto-conically shaped portion 112 of upper rotor part dish 80 upwardly through stacking 84 (by joint filling parts 100)。Compression stress is delivered to the hub 114 of upper rotor part dish 80 by six spokes radially extended 116 from frusto-conically shaped portion 112。Compression stress can be delivered to hub 114 due to the rigidity of upper rotor part dish 80 from frusto-conically shaped portion 112。What compression stress was reacted by upper rotor part dish 80 prevents (seeing Fig. 6 especially) along rotating shaft 78 axially-movable upwards by upper rotor part hub 114 being positioned in the peripheral recess 118 in the outer surface of rotating shaft 78。Frictional force between the outer surface of hub 114 and rotating shaft 78 prevents rotating against between them。

To be specifically seen from Fig. 6 and 8, the hub 114 of upper rotor part dish 80 extends to the point directly over end plate hub 98 along rotating shaft 78 axially downward。More particularly, hub 114 extends along the entire depth of separator disks stacking 84, and thus makes the hub 120 of each separator disks 82 separate (see Fig. 7) with rotating shaft 78。The hub 120 of each separator disks 82 has the hex shape limiting hexagon aperture, and rotating shaft 78 and upper rotor part hub 114 extend through this hexagon aperture。Separator hub 120 is relative to upper rotor part hub 114 (and therefore, relative to rotating shaft 78) rotary motion prevent by means of six keys 122, key 122 provides along the length of upper rotor part hub 114 vertically, and extends radially in six turnings in the hexagon aperture limited by separator hub 120。This position of key 122 prevents separator hub 120 relative to the lateral of rotating shaft 78 and rotary motion。

The separator hub 120 of each separator disks 82 is connected to the frusto-conically shaped portion 124 of each separator disks 82 by means of 12 spokes radially extended 126。Spoke 126 (and being in fact the remainder of the separator disks 82 being associated) is made up of relative thin and the plastic material that can flexibly bend。But, spoke 126 remains able to resist they experienced lateral and revolving forces and indeformable。Skilled artisan will appreciate that, the compression stress that helical spring 96 produces passes through separator disks stacking 84 via joint filling part 100 rather than by separator plate convergence 126。

Artisans will also appreciate that, the geometry that the hexagon hub 120 of each separator disks 82 is relative with key 122 guarantees that each separator disks 82 can be positioned on rotating shaft 78 in only six Angle Position as mentioned above。But, though use in six Angle Position which, the position, pole of the joint filling part 100 of separator disks 82 or Angle Position are all identical, and therefore, it is absent from such probability: in the unjustified situation of joint filling part 100 of adjacent separator disks 82, separator disks stacking 84 is assembled on rotating shaft 78。

In order to clear, some figure in accompanying drawing shows that the dish of the separator disks that there is the quantity reduced is stacking。Specifically simplify in an identical manner about prior art separator 2, Fig. 1,2,8,9 and 10。

As shown in Figure 5, second peripheral recess 128 position above the first recess 118 is provided in the upper end of rotating shaft 78。Second recess 128 receives the second spiral compression spring 130。The position of the second recess makes, in the prior art separator 2 assembled, the lower end of the second spring 130 spaced apart with the hub 114 of upper rotor part dish 80 (see Fig. 6), and lower end the moving axially downwards along rotating shaft 78 preventing the second spring 130 towards upper shoulder by being formed by the second recess 128。Additionally, in the separator 2 assembled, the cage of cage bearing 52 is adjacent and compression the second spring 130 (wherein the upper end of rotating shaft 78 keep spaced apart with the cap member 54 of top axle bearing unit 50 see Fig. 8 especially) downwards。Load is applied to top axle bearing unit 50 by the second spring 130, and thus reduces the vibration at top axle bearing unit 50 place and the abrasion being associated。

The fan except combination in second group of internals and all components except turbine unit 88 are shown as having assembled in Fig. 6 of accompanying drawing。When fan/turbine unit 88 is installed to the lower end of rotating shaft 78, central circular aperture that the lower end of axle 78 is passed through in each in the support plate 70 of first group of internals and housing insert 72 providing and position。So, the lower end of rotating shaft 78 also extends across the bottom bearing unit 90 (seeing Fig. 8 and 10 especially) in the center port being fixed to support plate 70。

Fan and the turbine unit 88 of combination are fixed to the lower end from the downward projection of rotating shaft 78 in the downside of support plate 70。Fan/turbine unit 88 is held in place on the lower end of rotating shaft 78 by means of second packing ring 133 towards upper surface of the second back-up ring 132 (being maintained in the 3rd peripheral recess in axle 78) and adjacent second back-up ring 132。Fan/the turbine unit 88 determined by the second back-up ring 132 axially location on rotating shaft 88 causes the upper surface of unit 88 to be forced into and deflects packing ring 139 and adjoin, and deflection packing ring 139 is forced into again and adjoins with bottom bearing unit 90。In the separator 2 assembled, the bias of adjacent first back-up ring 94 of the inside race of bottom bearing unit 90 and antagonism the first compression spring 96 presses up this back-up ring 94。Inside race, deflection packing ring 139 and fan/turbine unit 88 is pressed so to such an extent as to these elements to be maintained at the fixing position of rotation relative to rotating shaft 78 facing to the second back-up ring 132。

The direction that the rotor assembly of separator 2 indicates along arrow 134 (see Fig. 1) by means of hydraulic impulse turbine rotates。Fan/turbine unit 88 includes Pelton impeller 136, and this Pelton impeller 136 has the multiple wheel blades 138 being evenly spaced apart along its periphery。When using separator 2, the jet of oil is guided to the periphery of Pelton impeller 136 from the nozzle (not shown) in turbine shroud 178。More particularly, jet guides along the tangent line of the circle through multiple wheel blades 138 so that this jet enters wheel blade (with its surface in alignment)。Jet is along the described Surface runoff of the in-profile following wheel blade, and is turned to by described profile afterwards, in order to along other Surface runoff, and discharges from wheel blade afterwards。Result is that jet makes impeller 136 rotate。

The fan with multiple blade 140 also forms with impeller 136。Blade 140 is close to the downside of support plate 70 and is positioned on impeller 136。Multiple fan blade 140 are positioned at the axial positions roughly the same with bottom bearing unit 90 also along rotating shaft 78。Fan blade 140 extends radially outward near bottom bearing unit 90。It will be understood by those skilled in the art that fan blade 140 rotates around central axis 64 when turbine wheel 136 rotates。So, fluid is dished out by fan blade 140 effectively from the region between the downside of impeller 136 and support plate 70, thus the fluid pressure reduced in the region of bottom bearing 90, and from the position above support plate 70, isolated oil is drawn through downwards bottom bearing unit and enters the turbine shroud 178 below support plate 70。

For the ease of manufacturing, impeller 136 makes upper part 142 and low portion 144, and line 146 place shown in Fig. 8 of accompanying drawing is pressed onto adjacent to each other。

About first group of internals, support plate 70 is formed from steel and has round-shaped, and this is round-shaped has the diameter of substantially equal with the diameter of rotor case 4。Relative geometry so to such an extent as to allows support plate 70 to be located on the prone shoulder 148 of lower end of rotor case 4。By this way, the lower open end of rotor case 4 is closed by support plate 70。Support plate 70 is additionally provided with central circular aperture, and this central circular aperture is concentric with rotor case 4 in the separator 2 assembled。In other words, in the separator 2 assembled, the circular central aperture of support plate 70 is centered by the central axis 64 of rotor case 4。Additionally, as from Fig. 1 of accompanying drawing by particularly apparent, bottom bearing unit 90 receives in the center port of support plate 70。The radially portion part of bottom bearing unit 90 is fixed relative to support plate 70。The most radially inward portion of bottom bearing unit 90 is positioned near rotating shaft 78, but is not fixed on it。

As previously discussed, first group of internals also includes the housing insert 72 that is fixedly secured on support plate 70。Housing insert 72 acts as separation purifying gas and therefrom isolated oil, and provides the outlet 150 for purifying gas, and this outlet 150 is connected (seeing Fig. 1 especially) with the exit aperture 10 of rotor case 4。Housing insert 72 is provided as the moulded piece of plastic material。But, when housing insert 72 is described below, it will be considered that plug-in unit includes four parts: outer cylindrical wall/skirt portions 152；Ditch part 154；Frusto-conically shaped portion 156；And limit the exit portion 158 of described plug-in unit outlet 150。

The cylindrical skirt portions 152 of housing insert 72 has the most external external diameter of the diameter of the inner wall section being substantially equal to the rotor case 4 adjacent with skirt portions 152。Peripheral recess 159 (see Figure 12) is provided in the outer surface of skirt portions 152, in order to receiving O-ring packing 160, this O-ring packing 160 guarantees the fluid-tight between housing insert 72 chord transcapsidation body 4 in the separator 2 assembled。

The upside of the adjacent support plate 70 in the lower end of cylindrical skirt portions 152, and it is provided with the peripheral recess 162 (see Figure 12) for receiving the second O-ring packing 164。It will be appreciated that the second O-ring packing 164 ensure that the fluid-tight between housing insert 72 and support plate 70。

It is positioned at the radially inner side of external skirt part 152 and concentric the second cylindrical wall arranged is connected to skirt portions 152 at its lower end, to form ditch part 154。Ditch part 154 and external skirt part 152 collectively form the annular ditch (or groove) 166 that the inner cylinder wall along rotor case 4 extends。Ditch 166 has the cross section of u-shaped, and during using separator 2, collect and dish out from separator disks 82 and (and the effect of the gas stream spiraled downwards, as described in more detail herein) is travel downwardly under gravity in the inside of rotor case 4 isolated oil droplet。Ditch part 154 is provided with four discharge orifices 168 (seeing Figure 11 especially), collect in the oil in ditch 166 to pass through these four discharge orifices 168 and flow, in order to use the upside that is conveyed into the downside by housing insert 72 and support plate 70 during separator 2 around region。

The Part III 156 of housing insert 72 has Frusto-conical shape, and from cantilevered out ditch part 154。Frusto-conically shaped portion 156 is provided with central circular aperture, and this central circular aperture has the central axis that the central axis 64 with rotor case 4 overlaps in the separator 2 assembled。Elongated recesses 170 (see Figure 11) is provided in the upper surface of frusto-conically shaped portion 156。This recess 170 defines the fluid path linked for the exit portion 158 with housing insert 72 purifying gas。This flow path provided by recess 170 starts from its upstream extremity, has the downward step 172 from the upper surface of frusto-conically shaped portion 156。The sidewall 174,176 of recess 170 outwards develops from the center of housing insert 72 along with fluid path and is increased up height in downstream side。The top view of the housing insert 72 as provided from Figure 11 will become apparent to, and recess 170 provides the straight fluid path of the length of the half with the diameter being substantially equal to housing insert 72。

There is provided the exit portion 158 of housing insert 72 with the form of the pipe of general cylindrical, this pipe extends across the aperture in external skirt part 152 and the ditch between ditch part 154 166。

Show the view of the separator 2 being fixed on turbine shroud 178 in fig. 2。Separator 2 is fixed on turbine shroud 178 by means of three threaded securing members 180, and each in securing member 180 passes and in three lobe of lower end all-in-one-piece of rotor case 4。The side cross-sectional view of Fig. 2 shows only one securing member 180 and lobe 182。Those skilled in the art from Fig. 2 it will be appreciated that, support plate 70 (and, therefore all components of first group and second group) it is maintained at the desired location relative to rotor case 4 by means of turbine shroud 178, turbine shroud 178 is fastened to when going up each other is depressed into by support plate 70 adjoins with prone shoulder 148 at rotor case 4 and turbine shroud 178。Support plate 70 is clamped between rotor case 4 and turbine shroud 178 substantially by threaded securing member 180。Because threaded securing member 180 is tightened, and it is adjacent that support plate 70 and shoulder 148 are occurred, so, the second spiral compression spring 130 is compressed by top axle bearing unit 50。

When separator 2 operates, the jet of oil is directed on turbine wheel 136 by the nozzle (not shown) in turbine shroud 178, in order to revolving wormgear impeller in the direction indicated by the arrow 134, as previously described with respect to FIG 1。This rotation of turbine wheel drives rotor assembly to rotate as entirety central axis 64 around rotor case 4 on the direction of arrow 134。In other words, rotating shaft 78；Upper rotor part dish 80；Stacking the 84 of separator disks 82；End plate 86；And the fan of combination and turbine unit 88 (that is, being collectively referred to herein as rotor assembly) together as the black box rotated in housing 4 and rotate relative to described housing 4 and support plate 70, housing insert 72 and turbine shroud 178。

Release from engine crankshaft housing and need the fluid intake 8 at the gas processed by separator 2 top by being positioned at rotor case 4 to be introduced into separator 2。As shown in the arrow 68 in Fig. 8, inlet gas is being parallel to central axis 64 and the side with central axis 64 conllinear is upwardly into rotor case 4, and flows through three grooves 66 in top axle bearing unit 50 before flowing through six spokes 116 of upper rotor part dish 80。The rotary motion of six spokes also results in the lateral movement of the fluid between described spoke, because described fluid tangentially moves from the circular path of spoke 116, and the cylindrical wall efficiently towards rotor case 4 is outwards dished out。Substantially, cylindrical motion is given inlet gas by six spokes 116。

Inlet gas is downward through the spoke 116,126 of upper rotor part dish 80 and separator disks 82, and this gas laterally moves towards the cylindrical wall of rotor case 4 via the space between adjacent separator disks 82, shown in the arrow 184 in Fig. 8。Joint filling part 100 is pointed to the fluid in dish stacking 84 together with the frictional force applied by separator disks 82 and gives lateral movement, and this can cause that described fluid is outwardly directed to the cylindrical wall motion of rotor case 4。This motion of the fluid caused by the rotation of dish stacking 84 is that fluid is drawn in separator 2 main mechanism adopted。

It will be understood by those skilled in the art that oil droplet 186 tends to pool together and form bigger dripping at the periphery place of dish stacking 84。In this regard, act on the capillary force on less oil droplet (Small Distance due between adjacent separator disks 82) to tend to prevent droplet from dishing out from dish stacking 84。But, along with more oil moves through separator disks, smaller droplet pools together at periphery place, and forms bigger the dripping with the quality (and " being centrifuged " power being associated) being enough to overcome capillary force。Spontaneously throw afterwards on the cylindrical wall of rotor case 4。Once be received by described cylindrical wall, oil droplet 186 tends to travel down in annular ditch 166 under the effect of gravity and the gas stream passing through separator 2。The most external circumferential edge of separator stacking 84 is spaced inward fully relative to the cylindrical wall of rotor case 4, in order to allow oil droplet not traveled down in described ditch 166 by the obstruction of separator disks 82。O-ring packing 160 guarantees that oil droplet flows into ditch 166, rather than between housing insert 72 and rotor case 4 (it has the possible consequence (as will be better understood) of gas of the cleaning polluting the outlet 150 flowing through housing insert 72 with reference to Fig. 1)。

The oil droplet 186 collected in ditch 166 is therefrom emitted by four discharge orifices 168。This discharge effect is assisted by the FPG in rotor case 4 and turbine shroud 178。More particularly, it will be understood by those skilled in the art that the rotary motion due to rotor assembly, the fluid pressure in rotor case 4 is bigger in the peripheral edge place of separator disks stacking 84 is than the region between the upside of the downside of housing insert 72 and support plate 70。Result, it is intended to there is the downward purification gas stream by discharge orifice 168。This fluid stream tends to promote isolated oil droplet along annular ditch 166, and promotes it to pass downwardly through discharge orifice 168 and arrive on following support plate 70。This gaseous fluid stream is indicated (seeing Fig. 8 especially) by arrow 188。Gaseous fluid stream radially-inwardly moves through the upper surface of support plate 70 towards the central round orifice opening's edge in housing insert 72。This stream crossing support plate 70 tends to promote isolated oil droplet to cross support plate 70 towards bottom bearing unit 90, described oil droplet this bottom bearing unit 90 of traverse。The fan blade 140 of the fan of combination and the rotation of turbine unit 88 tends to the static pressure reducing in turbine shroud 178 in the region of bottom bearing unit 90。This contributes to again extracting oil droplet by bottom bearing unit 90。But, pump the major measure that oil droplet adopted by bottom bearing unit 90 to be provided by deflecting packing ring 139, in use, this deflection packing ring 139 rotates relative to support plate 70 together with turbine unit, and pump oil from rotor case 4, even if being also such when the pressure in the pressure ratio rotor case in turbine shroud is bigger。Then described outwards thrown in turbine shroud 178 by fan blade 140, and they can return to engine crankshaft housing from this turbine shroud 178。Meanwhile, the gaseous fluid flowing through support plate 70 is drawn upwardly the center port sent by package case 72, and leaves rotor case 4 by means of housing insert outlet 150 and rotor case outlet 10。

With reference to accompanying drawing it will also be understood that except flowing through discharge orifice 168, some purification in gas flow to outlet 150,10 (not flowing in ditch 166) via the alternative route between the upper part of end plate 86 and ditch part 154。This alternative route is indicated by arrow 190。

It will be appreciated that there is on bearing unit useful lubricant effect by the oil stream of bottom bearing unit 90。Top axle bearing unit 50 is similarly by being naturally occurring in turbine shroud 178 and being transferred up to the oily mist lubrication of top axle bearing unit 50 by extending the longitudinal flow path 92 of overwinding rotating shaft 78。

Although prior art separator 2 has turned out and effectively runs, but there are some problems being associated with this separator, they have utilized the improvement existed in the modified separator being described below to be addressed。These problems are regarded as three wide in range classifications。

First, causing the pressure loss by the fluid path of separator 2, this pressure loss can negatively affect the stream ability of separator and therefore affect the size of the electromotor that can use together with this separator。With prior art ALFDEX?Therefore the first kind problem that separator is associated can be considered relevant to the pressure loss in fluid flow path。

Second, the layout of prior art separator makes to purify gas under certain conditions and can become to be contaminated before leaving separator。Thus, it is believed that it is relevant with the undesirable greasy dirt dye purifying gas to the Equations of The Second Kind problem that prior art separator is associated。

3rd, some manufacturing technology being associated with prior art separator and architectural feature may result in assembling difficulty and/or integrity problem。Thus, it is believed that it is relevant with the manufacture of separator and reliability to the 3rd class problem that prior art separator is associated。

What will be discussed in more detail now in these classifications is all kinds of。

About the fluid flow path by this separator 2, there are some positions, the higher pressure loss can be experienced in these positions。First, the interior turning 40 of the elbow in inlet/outlet pipe joint 22,28 is too sharp-pointed to such an extent as to produce fluid in the region in the direct downstream at described interior turning 40 from the separation the inner surface of pipe joint。This separation manifests itself by recirculated fluid stream (or whirlpool), and it can cause again energy/pressure loss。But, as described by above with respect to Fig. 4 of accompanying drawing, provide big radius to be problematic as on interior turning when utilizing injection-molded or die-casting technique manufactures inlet/outlet pipe joint。As a result, prior art separator 2 when fluid enters rotor case 4 and leaves in 12 two kinds of situations of valve cell housing in the pipe joint place experience pressure loss。

Inventors have realised that the six of upper rotor part dish 80 spokes 116 are the other reasons of undesirable pressure loss。Specifically, seeing especially from Fig. 5 and 6, spoke 116 each has square-section, and the axial stream releasing gas entered is presented sharp-pointed upper trailing edge (see Fig. 5) at upper rotor part dish 80 when the side of arrow 134 rotates up by them。Have been found that the sharp-pointed trailing edge 192 of the shape of spoke 116, particularly each spoke, fluid can be caused to separate and undesirable pressure loss。

The inventors have also found that the specific structure of housing insert 72 can cause undesirable pressure loss。Specifically, using during separator 2, purifying gas and be downward through the frusto-conically shaped portion 156 of housing insert 72 with the such as rotary motion around central axis 64 shown in the arrow 194 in Figure 12。This purification gas stream flows downward with the pattern spiraled along the inner surface of the cylindrical sidewall of rotor case 4 and flows through frusto-conically shaped portion 156 afterwards。It will be appreciated that therefore, gas is purified from the week peritropous all regions (rather than entering described region a specific position) entered between frusto-conically shaped portion 156 and the end plate 86 of top along housing insert 72。Therefore the flow path striding across frusto-conically shaped portion 156 has eddy flow pattern, and this pattern can cause undesirable pressure/energy loss。Further it is provided that the step 172 of recess 170 in frusto-conically shaped portion 156 and wall 174,176 produce other flow separation zone and the undesirable pressure loss being associated。

About the Equations of The Second Kind problem being infected with pass with greasy dirt, the inventors have realized that some features of the prior art separator 2 of the probability that the air that can improve purification is contaminated under certain conditions。First, as described above, the stream purifying gas passing downwardly through rotor case 4 partially into ditch 166 and tends to extract isolated oil droplet out by discharge orifice 168。If the flow rate of the air purified is not high enough to for the specified level of processed greasy dirt dye, then collect in the oil droplet in ditch 166 and can climb up the ditch part 154 of housing insert 72, and then flow on the frusto-conically shaped portion 156 of housing insert 72 (see Figure 10)。Once oil droplet enters the region between frusto-conically shaped portion 156 and end plate 86, oil droplet just inevitably leaves separator 2 and pollutes purification gas。Oil droplet climbs from ditch 166 and is probably the result of the low flow rate purifying gas allowing undesirably substantial amounts of oil to collect in ditch 166。In ditch 166, there is the purification gas being circulated up also can tend to be drawn up oil droplet, and be drawn on the frusto-conically shaped portion 156 of housing insert 72。But, it is allowed to oil droplet climb emersion ditch 166 prior art separator 2 be noteworthy characterized by tubular outlet portion 158 (see Figure 12)。Although discharge orifice 168 is positioned on the both sides of exit portion 158, but will be appreciated by from Figure 12 of accompanying drawing, oil droplet in ditch 166 defers to the circular path of the bottom along ditch 166, if and oil droplet does not flow through discharge orifice 168 immediately upstream in exit portion 158, then oil droplet will tend to defer to the path that arrow 196 (see Figure 12) indicates, and flow upwardly through exit portion 158 and flow to the frusto-conically shaped portion 156 of housing insert 72。

The present inventors have additionally discovered that isolated oil droplet can flow upwardly through the center port of housing insert 72 and flow on frusto-conically shaped portion 156, and thus pollute purification gas。This undesirable stream of isolated oil tends to occur when the flow rate purifying gas by discharge orifice 168 and upwardly through the center port (arrow 188 in Fig. 8 is indicated) of housing insert 72 is of a relatively high。It will be appreciated by those skilled in the art that, purify the center port that the high flow rate of gas causes isolated oil droplet upwards to be carried by housing insert 72, rather than allow isolated oil droplet to be drawn through downwards bottom bearing unit 90 by the effect of gravity and deflection packing ring 139。

The present inventors have additionally discovered that, too much oil can be introduced into separator disks stacking 84 via the longitudinal flow path 92 through rotating shaft 78, indicated by the arrow 198 as shown in Fig. 2。During normal operating condition, drive impeller described in the oily jet impulse of turbine wheel 136 and produce the mist of thin oil droplet。This mist of oil is transferred up to top axle bearing unit 50, and transports through the stacking of separator disks 82 then downward。Generally, the amount of the oil transmitted by this way is enough to lubricate top axle bearing unit 50, is also easy to subsequently be isolated from the gas stream entered by separator disks stacking 84 simultaneously。But, in some cases, the amount transporting through the oil of rotating shaft 78 is likely to big to causing that oil spill goes out ditch 166 or otherwise flows on the frusto-conically shaped portion 156 of housing insert 72, and subsequently flows into purified gas outlet 10。This can such as occur when the surface of the oil storage that separator 2 tilts and the lower end of rotating shaft 78 is directly exposed to be maintained in turbine shroud 178。

About the threeth class problem relevant with the difficulty manufactured and reliability, the inventors have realized that the problems with about prior art separator 2。

First, about manufacturing separator 2, inventor have found that inlet/outlet pipe joint is fixed on rotor case 4 and valve cell housing 12 by the threaded securing member 32 of use possible consuming time, and need O-ring packing 36。

Manufacture the duration that spends of prior art separator 2 and be additionally subjected to need top axle bearing unit 50 with bottom bearing unit 90 so that the axially aligned impact of the mode that can rotate around same axis 64 of two bearing units 50,90。Specifically, rotor case 4 is made up of plastic material by means of injection molding process, and the inventors discovered that rotor case 4 during cooling exists the tendency of warpage。Due to this warpage, the position of the first cylindrical wall 60 (it is locator head bearing unit 50 laterally) of rotor case 4 is tended to be positioned at different lateral position relative to the lower end of rotor case 4 compared with expection。As a result, support plate 70 (and therefore bottom bearing unit 90) can become laterally to offset from its desired location。This problem can be cooled down on the relatively long time period after injection molding process by permission rotor case 4 and alleviate。This, section decreased the warpage of rotor case 4 long cool time, but was the increase in manufacturing time。

The other problem that assembling from separator 2 is associated relates between different components, such as the interface between rotor case 4 and valve cell housing 12。More particularly, if separator 2 will be provided with the valve cell 14 (or in fact just do not have valve cell) different from originally desired valve cell, then must also use different rotor housing 4, in order to guarantee the correct joint with new valve cell (or when by when not using valve cell for other tubing)。This can improve cost and built-up time inadequately。In addition, asymmetric (being caused for the moulded parts profile engaged with valve cell housing 12 by what provide on described housing 4) of rotor case 4 tends to cause described housing 4 warpage during manufacture, and this tends to cause during assembly problem (such as, with the unjustified relevant problem of component)。

Inventors have also recognized that, big O-ring packing 160 possible breakdown provided on housing insert 72。More particularly, it is necessary to O-ring packing carrys out the major diameter face seal against two couplings, and a surface provides on housing insert 72, and a surface provides on the cylindrical wall of rotor case 4。Rotor case 4 and housing insert 72 both have relatively larger foozle, and this may result in O-ring packing 160 can not correctly seal two components。Additionally, because two components use injection moulding technology to be made from a plastic material, each moulded parts moulded parts of rotor case 4 (and particularly) stands warpage after injection molding process。This can additionally result in O-ring packing 160 can not correctly seal two components 4,72。If it will be appreciated that O-ring packing 160 fault, then isolated oil would leak in the region 200 between the skirt portions 152 of the external cylindrical of housing insert 72 and the cylindrical wall of rotor case 4。The oil leaked in this region 200 will eventually enter into the outlet 150 of housing insert 72 and pollutes purification gas。If O-ring packing 160 fault on the position of outlet 150, then isolated oil will tend to leak and be directly entered outlet 150 through O-ring packing 160。Reduce warping effect (by increasing the cool time after injection molding process) when (i) takes steps to, or when (ii) replaces leaker after product test, this sealing problem can increase manufacturing time。

Additionally, the moulded parts burr being arranged in the recess 159 receiving O-ring packing 160 may result in O-ring packing fault。

Inventors have also recognized that and the integrity problem for being associated with the layout of fixing angular orientation positioning separator dish 82 relative to rotating shaft 78。Such as what set forth above with respect to Fig. 7 of accompanying drawing, prevent separator disks 82 from rotating relative to rotating shaft 78 by means of six keys (being fixed on rotating shaft 78) engaged with the hexagon aperture in hub 120 or each separator disks 82。But, the vibration (such as engine luggine) that separator is typically exposed to during use may result in the abrasion of the interface between the hexagon aperture in key 122 and hub 120。This abrasion may result in the significant relative rotary motion between separator disks 82 and rotating shaft 78。It is true that the inventors have discovered that adjacent separator disks 82 can relative to each other be rotated up to joint filling part 100 and become unjustified degree, thus the space between adjacent separator disks 82 is allowed to close。If this occurs in large number of dish 82, then the degree of depth of separator disks stacking 84 may decrease to the hub 98 so that end plate 86 and abutted against, by compression spring 96, the degree that upper rotor part hub 114 is compressed。It will be appreciated that then end plate 86 is no longer able to compression stress is delivered to separator disks stacking 84, and result, independent separator disks 82 will be free to move up and down (and rotating relative to rotating shaft 78) along rotating shaft 78 vertically。This motion is very undesirable, and can significantly decrease the separating property of separator disks stacking 84。

The other integrity problem that present inventors have recognized that relates between (i) rotating shaft 78 and top/bottom bearing unit 50,90；And

(ii) fretting wear of the seam between rotating shaft 78 and the first compression spring 96 is corroded。It will be understood by those skilled in the art that fretting wear corrodes to be likely between components have during relative motion (such as, due to cooperation relatively more loose between described component) to occur。Rotating shaft 78 extends through top with relatively more loose cooperation and bottom bearing unit 50,90 and the first compresses spring 96。This allows to compress spring 96,130 by first and second and axial prestrain is applied to top and bottom bearing unit 50,90。Specifically, it will be appreciated that bottom bearing unit 90 is applied axial force by the first compression spring 96 from accompanying drawing, and top axle bearing unit 130 is applied axial force by the second compression spring 130。The loose fit that rotating shaft 78 compresses spring 96 with top/bottom bearing unit 50,90 and the first allows the oscillating movement between these components。This can cause again the fretting wear on described component to corrode。Relative motion between component may also allow for hard granule and enters between described component, and this can further speed up abrasion and cause integrity problem。

The separator of the improvement for solving problem above of the present inventor's exploitation is described now with reference to Figure 13 to 41。

The separator immediately appreciating that improvement that the present inventor develops from accompanying drawing is had many components similar or identical in they performed functions and their ordinary construction with prior art separator 2 by those skilled in the art。Such component will pass through to use with the identical reference number used above with respect to prior art separator 2 hereinafter described in the context of the separator of improvement。For example, referring to Figure 13 of accompanying drawing, skilled artisan will appreciate that, the separator 2 ' of improvement shown in this Fig includes the rotor case 4 ' of general cylindrical, and it corresponds to the rotor case 4 of prior art separator 2 and performs similar function。Pass through accompanying drawing, 26S Proteasome Structure and Function difference between the component of such correspondence will be apparent from for technical personnel, but when difference is obvious when solving the problem about prior art separator 2 or the technique manufacturing prior art separator 2 and providing relative to the improvement of prior art separator 2 or the technique manufacturing prior art separator 2, these difference will be discussed substantially in detail。

It will be understood by those skilled in the art that the separator 2 ' of improvement includes the rotor case 4 ' of general cylindrical shape and acts as separating some fuel-displaced internals from the gas of the releasing being directed in described rotor case 4 '。As mentioned below, some in internals are positioned at rotor case 4 ', and other internals is (such as, the fan of combination and turbine unit) it is positioned at the outside of rotor case 4 ', however, it is positioned in another housing (such as, turbine shroud)。

The upper end of cylindrical housing 4 ' is provided with the annular shoulder 6 ' of setting, which defines the fluid intake 8 ' of the separator 2 ' leading to improvement。Release from crankshaft shell and need the gas therefrom removing oil to enter separator 2 ' via fluid intake 8 '。

Aperture 10 ' in the cylindrical wall 201 of rotor case 4 ' provides outlet, by this outlet, purifies gas and is sent to the independent housing 12 ' (seeing Figure 13 especially, 14 and 15) of valve cell 14 ' from the inside of rotor case 4 '。Exit aperture 10 ' extend through and therefore by cylindrical lobe 202 around, the lobe 202 of this cylinder extends from the outer surface of rotor case 4 ' itself。

Valve cell 14 ' includes arranging for the valve controlling the flowing purifying gas from separator 2 '。Due to the above description to prior art separator 2, the details of the operation of valve cell 14 ' will not be described herein。But, technical staff will be familiar with being used for the feature operation of the valve cell of separator improved。

As will become apparent to from Figure 13 and 14, and particularly will become apparent to from Figure 15, the internals of valve cell 14 ' is integrally centered around in the housing 12 ' separated with rotor case 4 '。More particularly, valve cell housing 12 ' includes Part I 203 and Part II 205, and they are fitted to each other and form the closing space of sealing, and the internals of valve cell 14 ' is arranged within this space。With reference to Figure 15, it will be seen that, the upper end of the Part I 203 of valve cell housing 12 ' is provided with lobe 207, and traditional threaded fastener 16 ' extends through this lobe 207, in order to be threadedly engaged with the other lobe 209 on rotor case 4 '。

From Figure 15 it will also be seen that, the lower end of the Part I 203 of valve cell housing 12 ' is provided with the part 211 of general cylindrical, this part 211 extends away from valve cell housing 12 ', and extends to the inside of rotor case 4 ' via the exit aperture 10 ' in rotor case 4 '。O-ring packing 213 is positioned on the outer surface of the part 211 of cylinder, and adjoins against shoulder (limit on said surface), this shoulder in the separator 2 ' assembled towards the inside of rotor case 4 '。When promoting described part 211 during assembly by exit aperture 10 ', shoulder is therefore prevented from O-ring packing 213 and moves along cylindrical the undesirable of part 211, and O-ring packing 213 engages with described aperture 10 '。More particularly, engage the face seal of O-ring packing 213 and the interior cylindrical of the lobe 202 around exit aperture 10 '。

When O-ring packing 213 towards cylindrical part 211 root end (namely, one end of adjacent with the remainder of valve cell housing cylindrical part) when providing, the second O-ring packing 215 is provided on the outer surface of the free end (away from root end) of the part 211 of cylinder。Identical with when first o-ring sealing member 213, second O-ring packing 215 abuts against on the shoulder of the inside of rotor case 4 ', in order to prevent undesirable motion of the second O-ring packing 215 when described sealing member is pressed into final utilization position in the separator 2 ' assembled。More particularly, from Figure 15 it will be appreciated that in the separator 2 ' assembled, the outlet 150 ' of the second O-ring packing 215 and housing insert 72 ' sealingly engages。

Artisans will also appreciate that, first o-ring sealing member 213 prevents purification gas and/or oil droplet from leaking between rotor case 4 ' and valve cell housing 12 ', and prevents them from thus undesirably leaking into environment from separator 2 '。Additionally technical staff it will further appreciated that, the second O-ring packing 215 prevents oil droplet from leaking into the outlet 150 ' of housing insert 72 ' and thus polluting the purification gas leaving rotor case 4 ' via cylindrical part 211。Cylindrical part 211 and the first and second O-ring packings 213, the little external diameter (compared with the major diameter O-ring packing 160 of prior art separator 2) of 215 allows to use relatively small foozle, this error guarantees the less trouble about two O-ring packings 213,215。In this regard, it will be appreciated that such as, the warpage degree of the cylindrical part 211 of relatively small diameter is by the rotor case 4 of the relatively large diameter less than prior art separator 2。

The lower end of the Part I 203 of valve cell housing 12 ' is provided with the second lobe 207 on the side of the part 211 of cylinder。Identical with the situation of the first lobe 207 provided on the upper end of Part I 203, the second lobe 207 on the lower end of Part I 203 receives traditional threaded fastener 16 ', to be threadedly engaged (seeing Figure 18 about described second lobe 207,209) with the second lobe 209 provided on the lower end of rotor case 4 '。

Owing to valve cell housing 12 ' is the housing separated with rotor case 4 ', and geometrically independent with it (except the part 211 of cylinder and mating and above and below lobe 207 of exit aperture 10 ', outside the joint of 209 pairs), the rotor case 4 ' of the separator 2 ' of improvement has the overall shape of more closely similar cylindrical overall shape compared with the rotor case 4 of prior art separator 2。In this regard, it is noted that prior art rotor housing 4 includes acting as the relative complex of the part (and being not only the matched interfaces about it) for forming prior art valve cell housing 12 and huge moulded parts profile on side。But, with reference to Figure 15, it will be seen that, the rotor case 4 ' of the separator 2 ' of improvement does not include aforementioned complexity and huge moulded parts profile。

Owing to rotor case 4 ' has the shape close with cylindrical shape, housing 4 ' can use injection moulding technology with cooling technique during compared with the housing 4 of prior art separator 2 amount of warpage of minimizing be fabricated by。This allows more easily to make top and bottom bearing unit 50 ', 90 ' axially aligned。In addition, will be appreciated by, as long as the rotor case 4 ' shown in accompanying drawing can couple with the alternative valve cell of the valve cell 14 ' shown in accompanying drawing-alternative valve cell has the cylindrical part 211 being applicable to mate with the exit aperture 10 ' of rotor case 4 ', and it is applicable to mate the lobe 207 of (valve cell housing 12 ' when) as shown in Figure 15 with the lobe 209 of rotor case 4 '。Such as, if alternative valve cell has the part with the cylinder identical with the part 211 and lobe 207 of the cylinder shown in Figure 15 and two lobe and the housing with the relative localization identical with shown in Figure 15, then alternative housing can be much bigger compared with the valve cell housing 12 ' shown in Figure 15, and hold with accompanying drawing shown in valve cell 14 ' inner valve arrange diverse inner valve layout。This allows the modular structure of separator 2 ', and wherein parts have the versatility of increase between the different layouts of separator。

With reference to Figure 15, it will be seen that, the housing 12 ' of valve cell 14 ' is provided with the setting annular shoulder 18 ' defining fluid issuing, by this fluid issuing, purifies gas and spreads out of from separator 2 '。Essentially identical with at the upper annular shoulder 6 ' provided of rotor case 4 ' at the upper annular shoulder 18 ' provided of valve cell housing 12 '。Owing to their similarity, entrance shoulder 6 and outlet shoulder 18 can receive the inlet/outlet pipe joint with identical interface profile interchangeably。Figure 13 shows the identical inlet/outlet pipe joint 22 ' with 90 ° of elbows。Show that inlet pipe joint 22 ' mates with the shoulder 6 ' of rotor case 4 ' with cross section, and additionally be shown as in fig. 17 separating with described shoulder 6 '。

As will be clear that from the side cross-sectional view of Figure 16, the curved surface combination of the inner surface of pipe joint 22 ' 216 and shoulder 6 ' limits to be had 90 ° of elbows and has the fluid flow path of radius significantly outside on turning and interior turning。As a result, compared with the fluid stream at the sharp-pointed turning 40 arranged through prior art, the trend that fluid separates from the interior turning of elbow reduces more。Then also reduce the pressure loss。

It is more fully described the interface between inlet/outlet pipe joint 22 ' and corresponding Housing shoulder 6 ', 18 ' now with reference to rotor case shoulder 6 ' (it is identical with the shoulder 18 ' of valve cell housing 12 ')。

As shown in figure 16 and 17, providing the setting shoulder 6 ' of rotor case 4 ' as annular relief, this annular relief has the general cylindrical wall 217 centered by the longitudinal axis to overlap with the central axis 64 ' of rotor case 4 '。The free end of cylindrical wall 217 (distant place of remainder at rotor case 4 ') is provided with formation and extends inward into the circumferential antelabium 219 of the curved surface 221 in the aperture formed by shoulder 6 '。In cross section (see Figure 16), curved surface 221 has part circular shape and extended the arc 223 of about 110 °。Part circular surface 221 is oriented so that the radial direction 225 on described surface 221 is parallel to the longitudinal axis of cylindrical wall 217 and extends。During specific shown in figure 16 is arranged, the swept arc 223 in part circular surface 221 terminates at aforementioned radial direction 225 place。From the side cross-sectional view of Figure 16 it will also be understood that the surface 227 of the external cylindrical of shoulder 6 ' overlaps with described radial direction 225, and intersect with part circular surface 221 and form the top edge 229 of shoulder 6 '。

In addition, referring specifically to Figure 16, it will be appreciated that, pipe joint 22 ' is provided with the profile mated with shoulder 6 ' so that the inner surface of pipe joint 22 ' 216 and the combination of the part circular surface 221 of shoulder 6 ' provide does not have convex ridge, shoulder, discontinuous and/or produce the smooth surface of any further feature of the pressure loss towards upstream/downstream。More particularly, the geometry of pipe joint 22 ' makes the transition part on the part circular surface 221 from the inner surface 216 of pipe joint 22 ' to shoulder 6 ' that obstruction or other pressure loss will not be utilized to produce feature and provides the fluid stream on the surface (by the either direction of pipe joint 22 ') through combination。Given shoulder 6 ' is symmetrical, and no matter pipe joint 22 ' is relative to how angle location or the pole of housing 4 ' position, and all keeping is this situation。

Seamlessly transitting between inner surface and the part circular surface 221 of pipe joint 22 ' is accomplished in that each some place being configured so that by the inner surface of pipe joint 22 ' at inner tube joint surface 216 with part circular surface 221 intersection in the layout of the separator 2 ' improved, and inner tube joint surface 216 is all oriented at the tangential of part circular surface 221。Therefore, interior turning about the elbow formed by pipe joint/shoulder combination, the preceding edge 229 place's intersection at shoulder 6 ' of inner tube joint surface 216 and part circular surface 221, and at this plotted point place, it is oriented orthogonal to aforementioned radial direction 225 (that is, tangent with part circular surface 221)。When a people advances to the outer corner of the elbow formed by pipe joint/shoulder combination circumferentially about shoulder 6 ', the point residing for the intersection of part circular surface 221 of inner tube joint surface 216 and shoulder 6 ' moves radially inwardly gradually through part circular surface 221。It can be seen that inner tube joint surface 216 is in edge 231 place of inner tube joint surface 216 and part circular surface 221 intersection in Figure 16。

In practice, due to the restriction of injection moulding technology and the cost constraint that is associated with high level error, the transition part between part circular surface 221 and inner tube joint surface 216 not necessarily will produce feature all without discontinuous or other pressure loss on the whole。Especially, can there is gap between the edge 231 of pipe joint 22 ' and the part circular surface 221 of shoulder 6 '。This gap in practice can by utilize die-casting technique manufactured by steel (or other metal material) in pipe joint 22 ' and part circular surface 221 or both and reduce。

Pipe joint 22 ' is additionally provided with the shoulder of the general cylindrical of cylindrical wall 233 form, its internal diameter with cylindrical wall 217 with Housing shoulder 6 ' and the equal internal diameter of external diameter and external diameter。When pipe joint 22 ' is positioned on described shoulder 6 ', the cylindrical wall 233 of pipe joint 22 ' mates with one heart with the cylindrical wall 217 of Housing shoulder 6 '。The wall 235 of bending is radially outward toward the top edge of pipe joint cylindrical wall 233 from aforementioned inner tube joint surface edge 231。In cross section, the shape of the wall 235 of bending is part circular, and is configured to concentric with the part circular surface 221 of Housing shoulder 6 ' and is adjacent。

Two fins 237 are positioned at the outside of pipe joint 22 ' and extend from the wall 235 of bending, in order to provide extra rigidity for described wall 235 and prevent or reduce the pipe joint 22 ' bending between the remainder (see Figure 13) of described wall 235 and pipe joint 22 '。

As, in prior art separator 2, the pipe joint 22 ' of the separator 2 ' of improvement uses traditional injection-molded or die-casting technique manufacture, result is to define sharp-pointed interior turning 239 (see Figure 34)。It is believed that this turning 239 is similar to the interior turning 40 of prior art pipe joint 22。It is to be appreciated, however, that the existence on the part circular surface 221 of Housing shoulder 6 ' combines the pipe joint 22 ' improved ensure that the interior section of the flow path elbow to housing 4 ' place provides radius。As the above mentioned, this is unrelated relative to the angular orientation of housing 4 ' with pipe joint 22 '。Separate from the fluid of the inner surface of elbow and be thus reduced or avoid, and the pressure loss in this part of flow path is reduced similarly or avoids。

Finally, about the geometry of pipe joint 22 ', second end (being provided with the distant place of one end of case interface profile) of described pipe joint is provided with tooth or sawtooth 38 ' on its outer surface, in order to grasp the flexible pipe being positioned on pipe joint the second end in use。

Emphasize again that to rotate Housing shoulder 6 ' identical with the shoulder 18 ' on valve cell housing 12 ', and outlet pipe connection 22 ' by with above with respect to rotor case shoulder 6 ' described identical in the way of be connected to this second Housing shoulder 18 '。

From above it will be appreciated that pipe joint 22 ' unobstructed can rotate while being positioned at shoulder 6 ' as shown in Figure 16 and be adjacent with this shoulder 6 '。Therefore, pipe joint 22 ' is rotatable is welded on shoulder 6 ', in order to required angular orientation, pipe joint 22 ' is fixedly secured to housing。It will be apparent to those skilled in the art that the method for fixing pipe joint 22 ' need not as used threaded securing member in prior art separator 2。It will also be understood that this rotating welding technology allows pipe joint 22 ' to fix with any angular orientation relative to housing 4 ', and whole circumference (or closed loop) is provided to seal without O-ring packing。Specifically, the period effect that the rotates against frictional force between the surfaces at housing 4 ' (that is, shoulder 6 ') with the abutment surface of pipe joint 22 ' heat produced causes described melt surface。Then turn off rotation and described surface cure, thus being bonded to each other。

Although above-mentioned rotating welding is the effective method being attached on the material of housing 4 ' by the material of pipe joint 22 '；But it is used as other method in conjunction with described material (such as, binding agent combines, ultra-sonic welded or Vibration Welding)。

To be more fully described aforementioned inner component referring specifically to Figure 34 now。

First, top axle bearing unit 50 ' is fixed to the inner surface of rotor case 4 ' in the direct downstream of fluid intake 8 '。Top axle bearing unit 50 ' is identical with the top axle bearing unit 50 of prior art separator 2, and therefore includes catching the cage bearing 52 ' between upper steel caps part 54 ' and the step parts 56 ' of plastic material。Top axle bearing unit 50 ' (and also having bottom bearing unit 90 ') includes roller bearing (in prior art separator 2), but can alternatively include sliding bearing or friction bearing。

More particularly, bearing holder component 56 ' has round-shaped and downward projection of cylindrical wall 58 ' (low portion around cap member 54 '), and it is positioned at the cylindrical wall 60 ' (but not laterally against it) of rotor case 4 ' in the separator 2 ' assembled。Cylindrical wall 60 ' downwardly extends from the upper inside surface of rotor case 4 '。Circular convex ridge 238 also downwardly extends from the upper inside surface of rotor case 4 ', and is positioned at the radially inner side of the first cylindrical wall 60 '。The cylindrical wall 60 ' of rotor case 4 ', circular convex ridge 238 and aforementioned shoulder 6 ' position concentrically with each other, and centered by the central axis 64 ' of rotor case 4 '。

As will hereinafter be described in more detail (with reference to Figure 37 to 41), top axle bearing unit 50 ' is fixed to the upper inside surface of rotor case 4 ' by means of rotating welding technology。Specifically, step parts 56 ' are welded on convex ridge 238。And use threaded securing member that top axle bearing unit 50 ' is fixed to rotor case 4 ' not as in prior art separator 2。This layout makes the rotation axis of top axle bearing unit 50 ' overlap with the central axis 64 ' of rotor case 4 '。

Top axle bearing unit 50 ' provides three part circular grooves 66 ' (only show two of which in Figure 34), in order to allow inlet fluid flow to cross wherein (as shown in arrow 68 ')。Upper cap member 54 ' deflects the entrance fluid from cage bearing 52 '。As, in prior art separator 2, the downside of the topmost part of cap member 54 ' also makes to travel up through during use lubricating oil mist deflection (in cage bearing 52 ') of armature spindle。

Remaining internals of separator 2 ' assembles independent of rotor case 4 ', and is then partially positioned in removedly in housing 4 ' as black box。As about prior art separator 2, it is believed that this black box includes keeping in use the first fixing fabric part and the second fabric part rotated around central axis 64 ' relative to rotor case 4 ' (and valve cell housing 12 ') and the first fabric part in use relative to rotor case 4 '。

First fabric part includes the support plate 70 ' of annular shape and the housing parts/plug-in unit 72 ' of dish type。As, in prior art separator 2, housing insert 72 ' and support plate 70 ' combine and act as each other for leaving the front isolation of rotor case 4 ' from purifying the isolated oil of gas at isolated oil and purification gas。Support plate 70 ' is formed from steel, and housing insert 72 ' is made up of plastic material。Support plate 70 ' and housing insert 72 ' are fixed to by means of three threaded fasteners 74 ' (see Figure 29) to be gone up each other, and these three threaded fastener 74 ' is threadedly engaged with the downward projection of lobe 76 ' in downside from housing insert 72 '。Support plate 70 ' closes the opening of rotor case 4 ', in order to providing the closed interior space of housing 4 ', the some components in the second fabric part are located therein。Thus, it is believed that rotor case 4 ' is the first housing parts limiting inner space, this inner space is for receiving for separate substance (such as, oil and gas) and the component that isolated material is directed to different outlets from described inner space。It is believed that support plate 70 ' is and the second housing parts of the first described inner space of housing parts restriction。

Discuss the first fabric part in this specification more fully below。

Second fabric part formed rotor assembly, and include rotating shaft 78 ', upper rotor part dish 80 ', collectively form separator disks 82 ' stacking 84 ' multiple independent separator disks 82 ', fan disk 240, end piece/plate 86 ', splash guard dish 242 and combination fan and turbine unit 88 '。Rotating shaft 78 ' is made up of metal material, and the remainder of the aforementioned components of second group is made up of plastic material and utilizes injection moulding technology manufacture。The aforementioned components of second group is by for preventing from or at least limit to be fixed in the way of they relative to each other rotate going up each other。Second fabric part additionally provides spiral compression spring (metal material), as described in more detail below。Second fabric part is rotatably mounted on the first fabric part by means of bottom bearing unit 90 ', and is rotatably mounted on rotor case 4 ' by means of top axle bearing unit 50 ' in the separator 2 ' assembled。

Rotor assembly that second fabric part formed be will be described in further detail now。

Rotating shaft 78 ' has ring section, in order to provide the fluid flow path 92 ' extended longitudinally along its whole length。When using separator 2 ', this flow path 92 ' allows oil mist transmit upwardly through rotating shaft from turbine shroud and be delivered to top axle bearing unit 50 ', in order to lubricate the bearing of described unit 50 '。Rotating shaft 78 ' be provided externally with some recesses and shoulder, they contribute to being maintained at component on rotating shaft 78 ' correct axial location。

Upper rotor part dish 80 ', separator disks 82 ', each in fan disk 240 and end plate 86 ' has the frusto-conically shaped portion (limiting upper and lower fi-ustoconical surface) being connected on the center hub element being positioned in use around rotating shaft 78 '。

When upper rotor part dish 80 ', separator disks 82 ' and end plate 86 ', frusto-conically shaped portion utilizes and multiple is connected to, from its radially inwardly extending spoke parts, the center hub element being associated。These spoke parts have the space opened between which, flow to allow fluid to pass axially through them along rotating shaft 78 '。

When fan disk 240, frusto-conically shaped portion 290 is connected to the center hub element 292 being associated by means of the second frusto-conically shaped portion 294。This second frusto-conically shaped portion 294 is continuous print, in order to convection cell provides and intercepts, and is therefore prevented from fluid and along rotating shaft 78 ' or is upward through fan disk 240 or is passed down through fan disk 240 and flows vertically。

The Frusto-conical shape of the second frusto-conically shaped portion 294 has the angle bigger than the angle of other frusto-conically shaped portion of the separator 2 ' improved。In other words, with the frusto-conically shaped portion of the situation of the first frusto-conically shaped portion 290 of fan disk 240 or upper rotor part dish 80 ', separator disks 82 ' and end plate 86 ' (and actually, the isolating roof parts 268 of the Frusto-conical shape of housing insert 72 ') situation (all of which all has identical angle) compare, the opposite side of the second frusto-conically shaped portion 294 is dispersed quickly/is assembled。Center hub element 292 is the cylindrical wall erect from the second frusto-conically shaped portion 294 (seeing Figure 26 and 33 especially)。The groove 296 (showing only one therein in Figure 26) extended longitudinally is provided by the whole thickness of the cylindrical wall of fan hub element 292, for the key 254 that reception radially extends from rotating shaft 78 '。By this way, it is therefore prevented that fan disk 240 is relative to the rotation of rotating shaft 78 '。

The downside of the first frusto-conically shaped portion 290 of fan disk 240 is provided with multiple joint filling part parts 298 that the central axis around fan disk 240 is equally spaced。Each joint filling part parts 298 are provided as the downward projection of straight convex ridge in downside from the first frusto-conically shaped portion 290, and extend to the radially edge, portion of the first frusto-conically shaped portion 290 in radial directions from the radially innermost portion edge of the first frusto-conically shaped portion 290。In the separator 2 assembled, joint filling part parts 298 adjoin the upper surface of the frusto-conically shaped portion of end plate 86 ', and therefore ensuring that the interval between fan disk 240 and end plate 86 ', fluid may pass through this interval (as indicated by the arrow 188 ' in Figure 34)。Using separator 2 ' period, the fluid rotated to be between fan disk 240 and end plate 86 ' of joint filling part parts 298 gives rotary motion。As a result, described fluid is outwardly directed to the cylindrical wall 201 of rotor case 4 ' and moves。Oil droplet (and/or, in fact other liquid entrained by gas stream or particulate pollutant) is dished out effectively facing to the cylindrical wall 201 rotating housing 4 ', and to dirty (or falling) to support plate 70 ' on。From between fan disk 240 and end plate 86 ' space discharge gaseous fluid or also flow downwardly into support plate 70 ' or directly off rotor case 4 ', as hereafter will be described in greater detail。

About end plate 86 ', the radially innermost portion circular edge of frusto-conically shaped portion 108 ' is connected to center hub element 98 ' (see Figure 18) by means of multiple spoke parts 110 '。But, the wall 300 of cylinder form also downwardly extends from the described radially innermost portion edge of frusto-conically shaped portion 108 '。In the separator 2 ' assembled, cylindrical wall 300 is centered by central axis 64 ', and downwardly extends fully along rotating shaft 78 ', in order to extended the center port provided in package case 72 '。Although described wall 300 has the shape of general cylindrical, but the inner surface 302 of described wall 300 defines Frusto-conical shape so that the internal diameter of cylindrical wall 300 reduces in an upward direction in the separator 2 ' assembled。The cylindrical outer surface of wall 300 has the diameter essentially identical with the center port of housing insert 72 ', and in the separator 2 ' assembled, is positioned in described aperture, makes to have between wall 300 and package case 72 ' minimum spacing。This closely cooperates, and while allowing rotating against between end plate 86 ' and package case 72 ', contributes to minimizing and can flow between described wall 300 and the center port of package case 72 ' to pollute the amount of the isolated oil of purification gas。It is sent in the space between fan disk 240 and end plate 86 ' additionally, the Inner frustoconical shape surface 302 of described wall 300 acts as resisting the oil droplet flowed up。It will be understood by those skilled in the art that the oil droplet of the fi-ustoconical surface of contact wall 300 will stand rotary motion, and due to the Frusto-conical shape on described surface, stand the power of effect downwards。

Splash guard dish 242 includes the annular disk 304 of plane, this dish 304 is connected to center hub element 308 by means of six spoke parts 306 radially inwardly extending from it, and this center hub element 308 is positioned at around rotating shaft 78 ' (seeing Figure 28 especially) in the separator 2 ' assembled。The diameter of the center port limited by the annular disk 304 of plane is substantially equal to the internal diameter of the lower end of the cylindrical wall 300 of end plate 86 '。Enter the fluid stream in region fan disk 240 and end plate 86 ' therefore junction surface place between splash guard dish 242 and end plate 86 ' through splash guard dish 242 to be absent from the significant pressure loss and produce feature。It will be appreciated that, annular disk 304 provides vibrating part, this vibrating part radially extends from the lower end edge of described cylindrical wall 300, and acts as any spacing between the outer surface for covering described cylindrical wall 300 and the part limiting the center port that described wall 300 extends through of housing insert 72 ' in use。By this way, the annular disk 304 of plane reduce isolated oil droplet spatter or otherwise move up from support plate 70 ' and through package case 72 ' center port in case pollute purify gas probability。

It will be further appreciated that, described region between fan disk 240 and end plate 86 ' defines flow path 616, outlet 620 (edge limited by the radial outer periphery of fan disk 240 and end plate 86 ') is arrived from entrance 618 (being limited by splash guard dish 242), as shown in Figure 34 for fluid traverse。

The hub element 308 of splash guard dish 242 provides as cylinder, and its upper end is by the wall Guan Bi of the plane being arranged perpendicularly to described cylindrical longitudinal axis (and, in the separator 2 ' assembled, be perpendicular to central axis 64 ')。Described cylindrical internal diameter is bigger than the external diameter of rotating shaft 78 ', and the wall of plane is provided with center port, and described axle 78 ' is this center port of traverse in the separator 2 ' assembled。This layout makes, in the separator 2 ' assembled, the cylinder of rotating shaft 78 ' and hub element 308 limits annular space between which, this annular space receives spiral compression spring 96 ', adjoin splash guard dish 242 is depressed into end plate 86 ', end plate 86 ' then abut against upper rotor part dish 80 ' pressure fan disk 240 and dish stacking 84 '。

It will be understood by those skilled in the art that splash guard dish 242 and end plate 86 ' separate manufacture, in order to allow the cylindrical wall 300 of end plate 86 ' to position through the center port of package case 72 '。If splash guard dish 242 and end plate 86 ' are one, then this will be impossible, because the external diameter of annular disk 304 is bigger than the diameter of the center port in housing insert 72 '。

As mentioned above, upper rotor part dish 80 ', fan disk 240 (about its first frusto-conically shaped portion) and the Frusto-conical geometry of end plate 86 ' and the geometry of separator disks 82 ' are essentially identical。This allows upper rotor part dish 80 ', fan disk 240 and end plate 86 ' stacking together with separator disks 82 ', and wherein, upper rotor part dish 80 ' is positioned at the top place of separator disks stacking 84 ', and end plate 86 ' is positioned at the bottom place of separator disks stacking 84 '。Fan disk 240 is arranged between the separator disks 82 ' of foot (that is, locating bottom it) of end plate 86 ' and separator disks stacking 84 '。

In addition, although skilled artisan will appreciate that separator disks 82 ' is by relatively thin for ratio, to allow to provide large number of dish in relatively short stacking 84 ', but upper rotor part dish 80 ' and end plate 86 ' are much thicker than separator disks 82 ', to provide rigidity at the two ends place of dish stacking 84 ', and consequently allow for, by means of upper dish 80 ' and end plate 86 ', compression axial force is evenly applied to the frusto-conically shaped portion of separator disks 82 '。It will be appreciated that compression stress is produced by described spiral compression spring 96 ', spiral compression spring 96 ' is pressed up on the downside of hub 308 of splash guard dish 242。Then, the hub 308 of splashproof guiding dish 242 is pressed up on the downside of adjacent hub 98 ' of end plate 86 '。

Compression about the dish stacking 84 ' between upper dish 80 ' and end plate 86 ', skilled artisan will appreciate that, as prior art separator 2, the adjacent separator disks 82 ' in stacking 84 ' must keep being spaced apart from each other, in order to allows fluid to flow through the separator 2 ' of improvement。This interval of separator disks 82 ' is provided in the separator 2 ' improved by means of multiple distance pieces 246。It is upper and from its outstanding point (see Figure 20) that each distance piece 246 is in the upper surface 102 ' of the frusto-conically shaped portion 124 ' of each separator disks 82 '。

Nethermost separator disks 82 ' in stacking 84 ' can be also spaced apart with fan disk 240 alternatively, in order to allows fluid to flow between which。If needing this interval, then use suitable distance piece。It is desirable that the upper surface of the first frusto-conically shaped portion of fan disk 240 (its second frusto-conically shaped portion being positioned at below the frusto-conically shaped portion of dish stacking 84 ' and by means of fan disk 240 is connected to fan hub) is provided with distance piece 246 in the way of identical with the frusto-conically shaped portion of each separator disks 82 '。

Each in described distance piece 246 has round-shaped, but can use other shape (such as, can use elliptical shape)。Preferably there is the edge of bending for any alternative shape of distance piece 246, in order to reduce the fluid pressure loss in the fluid flowing through distance piece。

First group of distance piece 246 is arranged in the circle concentric and adjacent with the inside circular edge 104 ' of described upper surface 102 '。Each distance piece 246 in this first group is positioned near the part of the frusto-conically shaped portion of inside circular edge 104 ', its mid-game 82 ' spoke link dish 82 '。Second group of distance piece 246 is arranged in circle that is concentric with the outer circular edge 106 ' of described upper surface 102 ' and that be adjacent。3rd group of distance piece 246 is arranged in the inner circular edge 104 ' of the frusto-conically shaped portion with dish 82 ' and outer circular edge 106 ' is concentric and in the circle of centre about between which。

As set forth more fully below, each separator disks 82 ' (and, actually, fan disk 240) can be positioned on rotating shaft 78 ' relative in rotating shaft 78 ' only three feasible Angle Position, and the location that distance piece 246 is on described upper surface 102 ' makes the distance piece 246 of the dish 82 ' adjacent when dish 82 ' is arranged in any one in these three position must be aligned with each other。In other words, when vertically separator disks 82 ' is shifted onto rotating shaft 78 ' upper and push it to adjacent to each other to form aforementioned stacking 84 ' time, necessary: each distance piece 246 of (i) specific dish 82 ' is located in stacking 84 ' and is positioned at directly over the distance piece 246 of adjacent dish 82 ' of described specific dish 82 ' lower section, and each distance piece 246 of (ii) specific dish 82 ' is located in stacking 84 ' and is positioned at immediately below the distance piece 246 of adjacent dish 82 ' of described specific dish 82 ' top。As a result, end plate 86 ' distance piece 246 being applied in the compression stress of dish stacking 84 ' the inc situation in interval between adjacent separator disks 82 by means of alignment passes through stacking 84 '。This guarantees that fluid remains able to flow between separator disks 82 '。

It will be appreciated that with reference to the accompanying drawings, distance piece 246 has little radial dimension and little circumferential size for the size of the separator disks being associated (diameter)。This allow fluid in the way of relatively not hindered by distance piece circumferentially direction flow through described dish upper surface 102 ', and radially flow through described surface 102 '。This pressure loss guaranteed in the fluid stream between adjacent dish 82 ' minimizes。

Figure 21 and 23 of accompanying drawing showing, other component of upper rotor part dish 80 ' and rotating shaft 78 ' and separator 2 ' is isolated。The hub 114 ' of upper rotor part dish 80 ' is molded on the outer surface of rotating shaft 78 ', and is hereby incorporated on described axle 78 '。This combination prevents rotating against between hub 114 ' and rotating shaft 78 '。

The hub 114 ' of upper rotor part dish 80 ' extends axially upward along rotating shaft 78 ', and terminates at the upper end of described axle 78 '。The upper part (the second spiral compression spring 130 ' is positioned at about) of rotating shaft 78 ' is thus provided with the coating (lining) of plastic material (preferred thermoplastic)。This coating protection spring 130 ', and particularly protection axle 78 ' corrodes from fretting wear。First group of the alternative of first embodiment 2 ' and second group of internals show in Figure 19。Except the plastic coating that the upper end part of wherein rotating shaft 78 ' is adjacent with the second helical spring 130 ', alternative separator is identical with first embodiment。

The hub 114 ' of upper rotor part dish 80 ' extends axially downward also along rotating shaft 78 ', and terminates at the some place directly over bottom bearing unit 90 '。Bottom bearing unit 90 ' is the metal end of contact rotating shaft 78 ' in the separator 2 ' assembled thus。More particularly, hub 114 ' extends along the entire depth of separator disks stacking 84 ', and thus makes the hub 120 ' of each separator disks 82 ' separate with rotating shaft 78 '。It will also be understood that hub 114 ' also provides the coating (lining) of plastic material (preferred thermoplastic) in the region of the first spiral compression spring 96 ' for rotating shaft 78 '。Additionally, this coating protection spring 96 ', and particularly axle 78 ', corrode from fretting wear。

The frusto-conically shaped portion 112 ' of upper rotor part dish 80 ' is connected to hub 114 ' by 12 spoke parts 116 ' radially extended。Each spoke parts 116 ' have the cross section of rectangular shape, and on it, the radially innermost portion circular edge 312 of described frusto-conically shaped portion 112 ' is adjoined in (little) side 310。Each spoke parts 116 ' extend axially downward from described edge 312。This layout makes when upper rotor part dish 80 ' is when using separator 2 ' period to rotate, and each spoke parts 116 ' play the effect of fan blade, and give motion on adjacent fluid。As will be understood by those skilled, the motion being given to fluid by each spoke parts 116 ' causes that fluid tangentially flows from the circular path of spoke parts 116 ', and frusto-conically shaped portion 112 ' lower section and effectively outwards dish out towards the cylindrical wall of rotor case 4 ' through dish stacking 84 '。As the function of fan blade, spoke parts 116 ' can cause that upper rotation dish 80 ' rotates, thereby through fluid intake 8 ' (as indicated by the arrow 68 ' in Figure 34) and by the space 600 between spoke parts 116 ' by gas suction rotor case 4 ', thus described space 600 represents the entrance of rotor assembly。

Enter three part circular grooves 66 ' in the fluid traverse top axle bearing unit 50 ' of rotor case 4 '。In the separator 2 ' assembled, the spoke parts 116 ' of upper rotor part dish 80 ' are positioned at the underface of three part circular grooves 66 '。Figure 34 referring specifically to accompanying drawing, it will be seen that the radial dimension of part circular groove 66 ' is less than the radial dimension (that is, length) of spoke parts 116 ', as a result, a very big part for the fluid of entrance only impacts the length of the underface being positioned at part circular groove 66 ' of spoke parts 116 ' at first。This length of each spoke element 116 ' is provided with the fluid stator 314 of side (or leading edge) 310 upwardly extending bending from it。The purpose of each stator 314 is to reduce or eliminate to separate, from spoke parts 116 ', the pressure loss being associated with entrance fluid。This is achieved in that provides the substantially axial stream of entrance fluid in the rotor case 4 ' with stator, this stator has the cross section of aerodynamic shape, and is oriented the string of the angle of attack (or being not result in another angle of attack that fluid separates from stator 314) about the fluid stream entered with basic zero degree。

Show the sectional view of length through the spoke parts 116 ' being provided with stator 314 in fig. 22。The surface of stator 314 acts as guiding the fluid of the leading edge 310 close to spoke element 116 ' to align with spoke element 116 '。The string 316 being associated with the leading edge 318 of stator 314 is oriented the angle of attack about the fluid flowing through described stator 314 with basic zero degree。This fluid is represented by arrow 320 relative to the direction of stator 314, and as indicated by Figure 22, is understood to be that (Q/A, wherein, Q is the volume fluid flow rate by entrance to (i) inlet fluid flow (amount)；And A is the area of section of inlet flow paths) axial velocity, and the tangential velocity of (ii) stator 314 (wherein, ω is upper rotor part dish is angular velocity to ω r；And r is the stator radial distance from center of rotation) function。Because fluid stream depends on the radial position r along stator 314 relative to the direction 320 of stator 314, string 316 can be oriented to the angle along with radial position changes。In other words, fluid stator 314 can be provided with torsion, in order to guarantees stator 314 and fluid stream correctly the aliging in all radial positions place along stator 314 entered。More particularly, the acute angle 322 between string 316 and vertical datum line 324 (parallel with the central axis 64 ' in the separator 2 ' assembled) can be gradually increased towards most external radial position along spoke parts 116 ' from penetralia radial position。

Skilled artisan will appreciate that, using the separator 2 ' period improved, the air entered flows through three part circular grooves 66 ' axially downward, and impact is being arranged in described groove 66 ' lower section short distance and around central axis 64 ' on the stator 314 that circular path rotates。Because the string 316 of the leading edge 318 of each stator 314 is oriented the angle of attack relative to the fluid stream entered with basic zero degree, described fluid flows through both low-pressure side 324 and the high-pressure side 326 of stator 314, and directed and flow on the axial direction relative to spoke parts 116 ', without separating from stator 314 or the spoke parts 116 ' that are associated are upper。The pressure loss produced by the fluid flowing through upper rotor part dish 80 ' is thus avoided or minimized。

The quantity that the other result of the reduction of the pressure loss that stator 314 provides is spoke parts 116 ' can increase (compared with prior art separator 2) without undesirably affecting by the fluid stream of separator 2 ' as overall flow rate。Increasing number of spoke parts 116 ' allow bigger compression stress to transmit between the frusto-conically shaped portion 112 ' and hub 114 ' of upper rotor part dish 80 '。Increasing number of spoke parts 116 ' also can improve the balance of upper rotor part dish 80 '。

It will be noted that Figure 22 presents stator 314 and the schematic diagram in the cross section of spoke parts 116 ' being associated, and not necessarily represent particularly preferred geometry or be in fact particularly preferred rotary speed and fluid flow rate。

With reference to Figure 21, it will be seen that cylindrical rim 328, it is provided as concentric with the radially innermost portion edge 312 of frusto-conically shaped portion 112 ' and erects from this edge 311。In the separator 2 ' assembled, rim 328 is positioned at radial outside relative to the downward projection of cylindrical wall 58 ' of top axle bearing unit 50 '。But rim 328 is located close to described cylindrical wall 58 ' place, in order to prevent (or significantly restriction) fluid leakage (seeing Figure 34 especially) between them。

Three keys 254 radially extend from the hub 114 ' of upper rotor part dish 80 ', as will be most readily visible from Figure 23 of accompanying drawing。These three key 254 is equally spaced around the central longitudinal axis of upper rotor part dish 80 ', and the following point along hub 114 ' is extended axially into along hub 114 ' (and hence along rotating shaft 78 ') from the downside 330 of spoke parts 116 ': the separator 2 ' assembled, this is approximately at centre along the center hub element 292 of fan disk 240。

Each key 254 has root portion 350 and tip portion 352。The remainder of root portion 350 and hub 114 ' links。Tip portion 352 is adjoined root portion 350 and provides free end to key 254。The root portion 350 of each key 254 is more wider than tip portion 352 (that is, having bigger circumferential size)。Due to the different in width of root portion 350 and tip portion 352, the junction surface between root portion 350 and tip portion 352 is on the both sides of each key 254 provides step 354。Referring specifically to Figure 23, it will be seen that, the width of the root portion 350 of each key 254 increases from the lower end of each key 254 to the upper end of each key 254。Additionally, the width of each root portion 350 is no better than the width (that is, circumferential size) of in 12 spokes 116 ' of upper rotor part dish 80 '。The tip portion 352 of each key 254 is also circumferentially alignd and abutting with spoke parts 116 '。

The hub 120 ' of each separator disks 82 ' has aperture 252, and rotating shaft 78 ' and upper rotor part hub 114 ' extend (seeing Figure 23 especially, 24 and 25) by this aperture。Preventing the separator hub 120 ' rotary motion relative to upper rotor part hub 114 ' (and therefore relative to rotating shaft 78 ') by means of three keys 254, these three key 254 provides and extends radially into, along the length of upper rotor part hub 114 ', corresponding the moon coupling profile that the aperture 252 of separator hub 120 ' limits vertically。This position of key 254 prevents separator hub 120 ' relative to the lateral of rotating shaft 78 ' and rotary motion。More particularly, the corresponding surface 358 (this surface 358 is also generally radially extending) of the adjacent described coupling profile in the surface 356 (this surface 356 is generally radially extending) of the tip portion 352 of each key 254, to prevent rotating against of separator disks 82 ' and upper rotor part hub 114 ' (and rotating shaft 78 ')。Will be appreciated by, in use, abutment surface 356,358 press up against in the side being generally perpendicular to each described surface 356,358 and to go up each other, and due to this reason, exist only small or there is no described surface 356, the sliding relative movement of 358, and described surface 356,358 only small or division (factional) abrasion (it may result in increase between separator disks 82 ' and upper rotor part hub 114 ' or undesirable rotates against) that is not associated。

The separator hub 120 ' of each separator disks 82 ' is connected to the frusto-conically shaped portion 124 ' of each separator disks 82 ' by means of 12 spoke parts 126 ' radially extended。As in the separator 2 ' of prior art, spoke 126 ' (and the remainder of the separator disks 82 ' being associated) by relative thin and the plastic material that can flexibly bend make。Again, in the separator 2 ' of prior art, spoke 126 ' can resist they experienced lateral and revolving forces without deforming, and the compression stress produced by helical spring 96 ' via distance piece 246 but not passes through separator disks stacking 84 ' by separator plate convergence 126。

Artisans will also appreciate that, as previously discussed, the key 252 of each separator disks 82 ' ensure that with the relative geometry in aperture 252 each separator disks 82 ' can be positioned on rotating shaft 78 ' in only three Angle Position。By means of the distance piece 246 location relative to aperture 252, the pole of the distance piece 246 of separator disks 82 ' or location, angle keep identical relative to rotating shaft 78 ', regardless of whether use in three Angle Position which, and therefore, be absent from the distance piece 246 of adjacent separator disks 82 ' unjustified time the separator disks stacking 84 ' probability that is assembled on rotating shaft 78 '。While it is true, each separator disks 82 ' be provided with can with the labelling of the label alignment of other dish 82 ' in dish stacking 84 '。By this way, all dishes 82 ' in stacking 84 ' will have identical Angle Position relative to rotating shaft 78 '。Labelling provides as being positioned on hub between two spokes 126 ' and extending radially outward short-range rib 256。

In order to clear, Figure 13, the 15,19,20,27,33,34 of accompanying drawing show that dish stacking 84 ' exists the separator disks that quantity reduces。

The annular recess 258 (see Figure 21) concentric with rotating shaft 78 ' provides on the upper surface of upper rotor part hub 211 '。Annular recess 258 receives the second spiral compression spring 130 ' and prevents this spring 130 ' along the motion axially downwards of rotating shaft 78 '。Additionally, in the separator 2 ' assembled, the cage of cage bearing 52 ' is adjacent and compresses downwards the second spring 130 ' (wherein the upper end maintenance of rotating shaft 78 ' is spaced apart with the cap member 54 ' of top axle bearing unit 50 ' sees Figure 34 especially)。

Assembling the separator 2 ' period improved, second group of internals is all connected to each other mutually except the fan of combination and turbine unit 88 '。Upper rotor part hub 114 ' (and remainder of upper rotor part dish 80 ') is together with rotating shaft 78 ' injection-molded in position。Stacking the 84 ' of separator disks 82 ' slide axially from its lower end edge then along rotating shaft 78 ', in order to the downside being positioned to the frusto-conically shaped portion 112 ' with upper rotor part dish 80 ' adjoins。

Before fan/turbine unit 88 is installed to the lower end of rotating shaft 78, the lower end of axle 78 is positioned through the support plate 70 in first group of internals and the central circular aperture provided in each in housing insert 72。So, the lower end of rotating shaft 78 also extends through bottom bearing unit 90, and this bottom bearing unit 90 is fixed to the center port (seeing Fig. 8 and 10 especially) of support plate 70。

Further with regards to the compression stress being applied to separator disks stacking 84 ', skilled artisan will appreciate that, this power is produced by spiral compression spring 96 '。Using separator 2 ' period, compression spring 96 ' rotates together with rotating shaft 78 ', and the lower end of compression spring 96 ' is adjacent with the inner radial seat ring of bottom bearing unit 90 ', in order to facing to its extrusion, and described power is passed up to splash guard hub 308。Then compression stress is delivered to end plate hub 98 ' from splash guard hub 308。Splash guard 242 is interrupted due to the frictional force (it will be understood as the effect of compression stress) between splash guard hub 308 and end plate hub 98 ' relative to the rotation of end plate 86 '。

Due to the rigidity of end plate 86 ', compression stress is delivered to the frusto-conically shaped portion 108 ' of end plate 86 ' from hub 98 ' by the plurality of spoke parts 110 ' radially extended。Compression stress then passes through frusto-conically shaped portion 108 ' and is delivered to the joint filling part parts 298 of fan disk 240, and is then passed up through stacking 84 ' (via distance pieces 246) from the frusto-conically shaped portion 290 of fan disk 240 and is sent to the frusto-conically shaped portion 112 ' of upper rotor part dish 80 '。Compression stress is delivered to the hub 114 ' of upper rotor part dish 80 ' from frusto-conically shaped portion 112 ' via 12 spokes radially extended 116 '。Compression stress can be delivered to hub 114 ' due to the rigidity of upper rotor part dish 80 ' from frusto-conically shaped portion 112 '。Upper rotor part dish 80 ' reacts on compression stress and axially-movable up along rotating shaft 78 ' is prevented by the position of the upper rotor part hub 114 ' adjacent with the prone shoulder 250 on rotating shaft 78 '。Upper rotor part dish 80 ' is prevented by the position with the upper rotor part hub 114 ' adjacent towards upper annular shoulder 248 on rotating shaft 78 ' downward along the axially-movable of rotating shaft 78 '。

The adjacent dish 82 ' of dish stacking 84 ' can be fixedly secured to go up each other alternatively。This by tend to raising dish stacking 84 ' rigidity and guarantee the relatively rotation place of adjacent dish 84 ' will not change (namely, it is ensured that dish distance piece 246 keeps alignment, in order to transmission compression stress and space between adjacent dish 82 ' will not close)。Dish 82 ' can be fixed on by welding (such as, ultra-sonic welded) and go up each other。

In prior art separator 2 ', before fan/turbine unit 88 ' is installed to the lower end of rotating shaft 78 ', the lower end of axle 78 ' is positioned through in each in the support plate 70 ' and housing insert 72 ' of first group of internals the central circular aperture provided。The lower end of rotating shaft 78 ' also extends through the bottom bearing unit 90 ' (seeing Figure 29 and 30 especially) of the center port being fixed to support plate 70 '。

Fan and the turbine unit 88 ' of combination are fixed to the lower end from the downward projection of rotating shaft 78 ' in the downside of support plate 70 '。Fan/turbine unit 88 ' is by means of back-up ring 132 ' (being maintained in the peripheral recess in the lower end of rotating shaft 78 ') and is positioned at around the lower end of rotating shaft 78 ' and being held in place on the lower end of rotating shaft 78 ' towards the spiral compression spring 360 on upper surface of adjacent back-up ring 132 '。

Back-up ring 132 ' and compression spring 360 are positioned at the fan of combination and the cavity of turbine unit 88 '。Compression spring 360 upwards compresses in described cavity, in order to fan/turbine unit 88 is upwards biased into the inner radial raceway contacts with bottom bearing unit 90 '。This layout is the most apparent from Figure 30 of accompanying drawing。With reference to this figure, it will be appreciated that be provided in described unit 88 ' towards upper deflector surface 139 ', and be positioned at the radially inner side of the fan blade 140 ' of described unit 88 '。Deflector surface 139 ' performs the function identical with the deflection packing ring 139 in prior art separator 2, but provides integratedly with fan/turbine unit 88 ', rather than the adjoining members separated。The radial inner portion of deflector surface 139 ' is pressed upward the inner race with bottom bearing unit 90 ' and adjoins, and this inner race is pressed upward again and comes on support plate 70 '。The radially outer bearing race of deflector surface 139 ' and bottom bearing unit 90 ' is spaced apart from each other vertically, in order to allow isolated oil be downward through bottom bearing unit 90 ' and flow radially outwardly through described axially spaced-apart and enter turbine shroud。

The rotor assembly of separator 2 rotates up (see Figure 29 and 30) by means of hydraulic impulse turbine in the side indicated by arrow 134 '。As, in prior art separator 2 ', fan/turbine unit 88 ' includes the Pelton impeller 136 ' with the multiple wheel blades 138 ' being evenly spaced apart along its periphery。When using separator 2 ', the jet of oil guides the periphery to Pelton impeller 136 ' from the nozzle (not shown) in turbine shroud。More particularly, tangentially directed along the circle through multiple wheel blades 138 ' of jet so that jet enters the wheel blade with its surface in alignment。Jet is along the described Surface runoff of the in-profile deferring to wheel blade, and is rotated by described profile afterwards, with along other Surface runoff, and discharges from wheel blade afterwards。Result is that jet makes impeller 136 ' rotate。

The fan with multiple blade 140 ' also forms with impeller 136 '。Blade 140 ' is close to the downside of support plate 70 ' and is positioned on impeller 136 '。The plurality of fan blade 140 ' is on the axial location roughly the same with deflector surface 139 ' and bottom bearing unit 90 ' also along rotating shaft 78 '。Fan blade 140 ' extends radially outward near bottom bearing unit 90 '。It will be understood by those skilled in the art that when turbine wheel 136 ' rotates, fan blade 140 ' rotates around central axis 64 '。So, fluid is dished out by fan blade 140 ' effectively from the region between impeller 136 ' and the downside of support plate 70 ', thus the fluid pressure reduced in the region of bottom bearing unit 90 ', and contribute to being drawn through downwards bottom bearing unit from the position of support plate 70 ' top and pumping to the turbine shroud of support plate 70 ' lower section by isolated oil。

For the ease of manufacturing, impeller 136 ' makes upper part 142 ' and low portion 144 ', and is pressed onto adjacent to each other by two threaded fasteners (only show one of them in Figure 30 of accompanying drawing) online 146 ' places。

The upper part 142 ' of the plurality of fan blade 140 ' and deflector surface 139 ' and fan/turbine unit 88 ' forms。The low portion 144 ' of fan/turbine unit 88 ' is provided with lower plate member 364, in the separator 2 ' assembled, during lower plate member 364 is located normal to central axis 64 ' and strides across the plane of the lower opening opened wide to the flow path 92 ' of rotating shaft 78 '。While it is true, plate member 364 and the described open space leading to flow path 92 ' are opened, in order to allow fluid to flow into described opening。

Plate member 364 is provided with four apertures 366, and aperture 366 equidistantly positions along the imaginary circles centered by central axis 64 ' in the separator 2 ' assembled。It will be understood by those skilled in the art that the aperture 366 that can use alternative quantity, but aperture should be arranged so as to guarantee the spin balancing of fan/turbine unit 88 '。

Importantly, aperture 366 is positioned at the radial outside of the opening leading to flow path 92 '。It will be appreciated that therefore, this layout makes the mist of oil droplet can flow upwardly through aperture 366 and hence into the cavity in fan/turbine unit 88 ' from turbine shroud, and flows upwardly through the flow path 92 ' of rotating shaft 78 '。But, it will also be appreciated that being flowing in direction radially inward from aperture 366 to the described opening of flow path 92。Using separator 2 ' period, fan/turbine unit 88 ' rotates up in the side that arrow 134 ' indicates certainly, and the mist of oil droplet can flow flow path 92 ' radially inward from aperture 366 simultaneously, the comparatively large number of oil flowing through aperture 366 will be moved by the plate member 364 laterally direction spinned, and tends to be dished out by the outward opening away from flow path 92 '。Such as, at inclination of vehicle or additionally so that upwards spilling oil so that the mode pouring the cavity of fan/turbine 88 ' moves from turbine shroud by aperture 366, the lateral movement for the oil imparting in described cavity is tended to prevent described oil inwardly rotating shaft 78 ' from flowing。Therefore avoid substantial amounts of oil undesirably flow upwardly through rotating shaft 78 ' and enter dish stacking 84 '。

Plate member 364 provides two discharge orifice 368, in order to allow oil to drain back into turbine shroud from the cavity in fan/turbine unit 88 '。It is relative to each other that discharge orifice 368 is located along diameter, and forms groove in plate member 364 and in the general cylindrical wall erect from the circular periphery of described plate member 364。The position of the discharge orifice 368 in the radially portion part of turbine cavity guarantee away from rotating shaft 78 ' dish out described cavity neighboring oil be really effectively discharged out from fan/turbine unit 88 '。

Although the low portion 144 ' showing plate member 364 and fan/turbine unit 88 ' in the embodiment of Figure 29 and 30 is one, but in the alternative shown in Figure 31 and 32 of accompanying drawing, end plate 364 provides as the circular discs separated with the low portion 144 of fan/turbine unit 88 '。With reference to Figure 31 and 32, it will be seen that, the plate member 364 of the separation of alternative is the circular discs being provided with aperture 366 in the way of identical with Figure 29 and 30。But, alternative plate member 364 is in position relative to the remainder of fan/turbine unit 88 ' by threaded fastener 362 (extending through them), and does not have discharge orifice 368。In this alternative arrangement, only providing discharge orifice 368 in the cylindrical wall of low portion 144 ', it is arranged to concentric with the circular periphery edge of plate member 364 and upwardly extends from this edge。The low portion 144 ' of fan/turbine unit 88 ' is additionally provided with the second cylindrical wall 370, second cylindrical wall 370 is positioned at the cavity of fan/turbine unit 88 ' and extends downwardly so as to provide prone annular surface, can be faced toward this annular surface pressing plate component 364 by two threaded fasteners 362。Prone annular surface provides recess, in order between described cylindrical wall 370 and plate member 364, provide fluid path 372。In use, the oil of the upper surface flowing outwardly through plate member 364 is sent to discharge orifice 368 via flow path 372。

Although the fan/turbine unit 88 ' of Figure 31 and 32 is provided with the outer cylindrical wall together defining cavity and plate member 364, and it is further provided with plate member 364 and abuts against the other cylindrical wall 370 of its location, but fan/turbine unit 88 other side be similar to prior art separator 2 in, and be fixed to rotating shaft 78 ' in the way of identical with prior art separator 2。Specifically, fan/turbine unit 88 ' is fixed to rotating shaft 78 ' by means of packing ring 133 ', and packing ring 133 ' is pressed up to upper and by means of the peripheral recess on the outer surface being arranged in rotating shaft 78 ' the back-up ring 132 of low portion 144 ' of described unit 88 ' and is held in place。It will be appreciated that packing ring 133 ' and back-up ring 132 provide alternative fixing means for the compression spring 360 shown in Figure 29 and 30 and back-up ring 132。

About first group of internals, support plate 70 ' has round-shaped, and this is round-shaped has the diameter of substantially equal with the diameter of rotor case 4 '。As, in prior art separator 2 ', relative geometry so to such an extent as to allows support plate 70 ' to be positioned on prone shoulder 148 ' at the lower end of rotor case 4 '。By this way, the lower open end of rotor case 4 ' is closed by support plate 70 '。But, in the separator 2 ' improved, the lower open end of rotor case 4 ' adjoins the upside of support plate 70 ' and is provided with peripheral recess 260, and this peripheral recess 260 is used for receiving O-ring packing 262 (see Figure 34)。It will be appreciated that the second O-ring packing 262 ensure that the fluid-tight between rotor case 4 ' and support plate 70 '。

Additionally, in the separator 2 ' assembled, circumferential edge surface, radially portion 630 (formation datum level) registration of support plate 70 ' becomes the cylindrical inner surface 632 with the lower open end around rotor case 4 ' to adjoin。By this way, support plate 70 ' is laterally aligned relative to rotor case 4 ' desired final position (see Figure 13)。

Support plate 70 ' is additionally provided with central circular aperture, and in the separator 2 ' assembled, central circular aperture is concentric with rotor case 4 '。In other words, in the separator 2 ' assembled, the circular central aperture of support plate 70 ' is centered by the central axis 64 ' of rotor case 4 '。Additionally, as will especially it will be apparent that bottom bearing unit 90 ' receives in the center port of support plate 70 ' from Figure 34 of accompanying drawing。The radially portion part of bottom bearing unit 90 ' is fixed relative to support plate 70 '。The most radially inward portion of bottom bearing unit 90 is positioned near rotating shaft 78 ', but is not secured on it。

As previously discussed, first group of internals also includes the housing insert 72 ' that is fixedly secured on support plate 70 '。As, in prior art separator 2 ', housing insert 72 ' acts as making purification gas and therefrom isolated oil isolation。The housing insert 72 ' of the separator 2 ' improved additionally provides the outlet 150 ' for purifying gas, and the cylindrical intake section 211 (see Figure 15) of this outlet 150 ' and valve cell housing 12 ' is directly connected to hermetically。

Housing insert 72 ' provides as the moulded parts of the one of plastic material。But, when housing insert 72 ' is described below, it will be considered that plug-in unit includes four parts: there is the outside deflector wall 264 of Frusto-conical shape；There is the abutment wall 266 of the shape of cylinder；There are the isolating roof parts 268 of Frusto-conical shape；And limit the exit portion 270 of described plug-in unit outlet 150 ' (seeing Figure 27 and 28 especially)。

The isolating roof parts 268 of housing insert 72 ' have Frusto-conical shape and are bearing in abutment wall 266。Isolating roof parts 268 are provided with central circular aperture, and in the separator 2 ' assembled, this central round orifice mouthpiece has the central axis that the central axis 64 ' with rotor case 4 ' overlaps。The upper surface of isolating roof parts 268 provides elongated channel/recess 272 (see Figure 28)。This path/recess 272 defines the fluid path for purifying gas, and it extends to the exit portion 270 (having tubular form) of housing insert 72 ' from the entrance 282 of recess 272。Entrance 282 is limited by the recessed circumferential portion at the upper circular periphery edge 274 of isolating roof parts 268。Entrance 282 is positioned to the exit portion 270 with housing insert 72 ' substantially diametrically。The aforementioned recessed part of described periphery edge 274 extended the arc 280 of about 80 °, and this arc is centered by the described central axis in housing insert aperture。In an alternative embodiment, the entrance of fluid path can recessed partially defined by the excessively different arc (such as between 45 ° and 110 °) of the extension in described periphery edge 274。In the separator 2 ' assembled, only little distance separates isolating roof parts 268 and end plate 86 '。Result, thinking that the major part purifying gas in the region 606 entered between isolating roof parts 268 and end plate 86 ' carrys out do so (entrance) by the space between aforementioned recessed part and the end plate 86 ' of described periphery edge 274, only relative small portion purifies gas and flows into described region through the remainder of described periphery edge 274。

It will be appreciated that, therefore the space between whole circumference periphery edge 274 and end plate 86 ' provides the entrance 610 in the described region 606 between isolating roof parts 268 and end plate 86 ', but because the part 612 of a length direction of this entrance 610 is (namely, the entrance 282 of path/recess 272) there is the bigger degree of depth 613 (namely than the part of other length direction of entrance 610, bigger axial spacing between periphery edge 274 and end plate 86 '), so flow into described region 606 purify gas most carry out do so by the part 612 of the described length direction with the bigger degree of depth 613。The degree of depth of the part of remaining length direction of described area entry (610) is minimum, in order to minimizes the fluid stream through them, and thus also minimizes oil droplet passing through through them。The degree of depth of the part of remaining length direction can between 1/10th and half of the bigger degree of depth 613, but described in being preferably 1/3rd of the bigger degree of depth 613。

Using separator 2 ' period, the gas that purifies leaving separator disks stacking 84 ' flows downward along the inner surface of the cylindrical wall of rotor case 4 ' with the rotary motion spiraled。It will be appreciated that the purification gas hence into the aforementioned areas 606 between isolating roof parts 268 and end plate 86 ' tends to utilize the rotary rotational flow motion centered by the central axis 64 ' of rotor case 4 ' to carry out do so。But, the gas stream entering described region 606 via entrance 282 is directed to plug-in unit outlet 150 ' immediately by means of the sidewall 276,278 of elongated recesses 272。It is additionally considered that this guiding purifying gas stream can reduce the rotary rotational flow motion purifying gas immediately after described gas enters described elongated recesses 272 via recess entrance 282。In this regard, from Figure 28 of accompanying drawing it will be seen that, the upstream portion of elongated recesses 272 is the bending (sidewall 276 of recess 272,278 thus with the entrance stream into alignment of eddy flow, to minimize desirable going significantly pressing (unpressure) loss when fluid initials assault sidewall 276,278) and straighten gradually when flow downstream moves along recess 272 towards plug-in unit outlet 150 '。Thinking compared with above-described prior art separator 2, the minimizing immediately of the swirling motion in the major part of the gas of the cleaning in the region between entrance isolating roof parts 268 and end plate 86 ' can significantly decrease the pressure loss in the fluid of this part flowing through separator 2 '。

Will be appreciated by, the purification gas still entering the region between isolating roof parts 268 and end plate 86 ' in other position of the periphery along isolating roof parts 268 without flow through entrance 282 will tend to flow through described region with swirling motion, until being received by elongated recesses 272, hereafter, think that particularly radial exterior side wall 276 will guide fluid to export 150 ' towards plug-in unit, and also reduce the swirling motion of described fluid。

Cylindrical abutment wall 266 is disposed concentrically upon with the central circular aperture in isolating roof parts 268, and is downwardly projected from the downside of isolating roof parts 268。The diameter of abutment wall 266 is less than the diameter of the periphery edge 274 of isolating roof parts 268。In the separator 2 ' assembled, the prone lower circular edge 450 (see Figure 27) of abutment wall 266 adjoins support plate 70 ' (junction surface place between which)。Isolating roof parts 268 are thus bearing on support plate 70 ' by abutment wall 266, and guarantee the isolating roof parts 268 correct axial location relative to support plate 70 '。Abutment wall 266 is additionally provided with the lobe 452 of multiple cylinder, and each of which has the recess for receiving securing member 74 ' threadably。In the separator 2 ' assembled, each securing member 74 ' extends in described lobe 452 from the aperture passed under support plate 70 ' of support plate 70 '。By this way, package case 72 ' is fixedly secured on support plate 70 '。

The prone lower circular edge 450 of abutment wall 266 is provided with the multiple aperture/recesses 454 being positioned at multiple position along described edge 450。As seen from Figure 27 and 34 especially, recess 454 provides space between abutment wall 266 and support plate 70 ', is using the separator 2 ' period assembled, and fluid can flow through this space。Specifically, using separator 2 ' period, from the isolated oil multiple recesses 454 of traverse that the cylindrical wall of rotor case 4 ' flows radially inward along support plate 70 '。The part purifying gas also flows radially inwardly through the upper surface (skilled artisan will appreciate that) of support plate 70 ', and this fluid also flows through multiple recess 454。This fluid stream is indicated by the arrow 188 ' in Figure 34。

Outside deflector wall 264 downwardly extends from the periphery edge 274 of isolating roof parts 268。Deflector wall 264 has the Frusto-conical shape dispersed towards support plate 70 ' in a downwardly direction in the separator 2 ' assembled from isolating roof parts 268。Diameter that deflector wall 264 is located at its upper end (and therefore, the diameter of the periphery edge 274 of isolating roof parts 268) is substantially equal to the external diameter of separator disks stacking 84 '。Due to the Frusto-conical shape of deflector wall 264, when moving in a downwardly direction, deflector wall 264 is assembled about the general cylindrical wall of rotor case 4 '。The sectional area of the flow path between deflector wall 264 and rotor case 4 ' (that is, in a downward direction) reduces therefore in the flowing direction。The lower free end 608 of deflector wall 264 is positioned to spaced apart with the cylindrical wall of rotor case 4 ', and between 2 millimeters and 200 millimeters spaced above of support plate 70 ' and the preferred distance 456 of 14 millimeters。Outside deflector wall 264 allows isolated oil (or other material separated) and purification gas (it does not enter into first area entrance 610) to flow downward along the cylindrical wall of rotor case 4 ' with this interval of rotor case 4 ' and support plate 70 ', and flows radially inwardly through deflector wall 264 (including its free end) along support plate 70 '。So, isolated oil and purification gas flow through the second area 614 on the side contrary with the first flow region 606 of housing insert 72 '。

Being additionally, since its Frusto-conical shape, when moving in downward direction, outside deflector wall 264 is dispersed from cylindrical abutment wall 266。The abutment wall 266 of outside deflector wall, isolating roof parts 268 and cylinder limits the cavity 458 (see Figure 34) of the generally annular shape with unlimited lower end。This layout so to such an extent as to reduce isolated oil along rotor case 4 ' be downward through recess 272 entrance 282 only because the recirculation of fluid and flow up and thus flow into described entrance 282 subsequently and pollute the probability purifying gas。

More particularly, although the relatively large spacing between the upper end of rotor case 4 ' and deflector wall 264 allows isolated oil easily to enter between these features, but the smaller spacing at the lower free end of deflector wall 264 between these features can reduce isolated oil can upwards be splashed into or be recycled to the easiness between described free end and rotor case 4 '。Additionally, any recirculation of the fluid near the radial outer periphery of support plate 70 ' will tend to lead to isolated oil flows into abovementioned cavity 458。Such as, isolated oil can flow up along the radially-outer surface of cylindrical abutment wall 266, along isolating roof parts 268 downside outwardly, and the inner radial surface then along deflector wall 264 flows downward。In due course, oil is fallen support plate 70 ' from cavity 458 under gravity by being likely to。Flow up in the way of causing polluting the risk purifying gas in the region flowed between isolating roof parts 268 and end plate 86 ' it will be appreciated that this recirculation flow path is not result in isolated oil。Therefore, once purify gas to flow through region 606 entrance (namely towards support plate 70 ', lead to the entrance between isolating roof parts 268 and end plate 86 '), it is prevented that upstream towards any recirculation subsequently that described entrance returns, described gas causes that the gas of recirculation (and the oil droplet carried by it) enters described region 606 by deflector wall 264, this gas that can be effectively isolated described recirculation and described entrance (that is, keeping it to separate)。

The exit portion 270 of housing insert 72 ' is provided as cylindrical tube element, the tube element of this cylinder opens wide (and more specifically to the upper surface of isolating roof parts 268, open wide to the recess 272 being used for receiving purification gas), and abutment wall 266 and outside deflector wall 264 is extended through in generally radially outwardly direction。As from Figure 13 and 14 of accompanying drawing by particularly apparent, exit portion 270 is positioned on the prone edge of abutment wall 266。Therefore, in the separator 2 ' assembled, exit portion 270 is positioned at support plate 70 ' top so that fluid can at exit portion 270 flowing underneath。Advantageously, isolated oil can at exit portion 270 flowing underneath, and therefore, be not inclined to the periphery edge 274 towards isolating roof parts 268 climb exit portion 270 outer surface on, herein, isolated oil can easily pollute the gas of the cleaning of the recess 272 flowing into housing insert 72 '。Exit portion 270 at it, to one end that recess 272 opens wide, free end at a distance is provided with supporting member 460, supporting member 460 is downwardly projected from the bottom part of described free end, in order to adjacent support plate 70 '。By this way, supporting member 460 contributes to maintenance minimum spacing between support plate 70 ' and exit portion 270, but also allows support plate 70 ' to provide supporting to the free end of exit portion 270。

During assembly, separator 2 ' is to be fixed to turbine shroud (not shown) with above with respect in the way of similar described by prior art separator 2 '。Specifically, the separator 2 ' improved is fixed to turbine shroud by means of four threaded securing member (not shown)s, the lobe (seeing Figure 18 and 29 especially) that the traverse of each threaded securing member is different from four lobe 284 of lower end all-in-one-piece of rotor case 4。

It will be appreciated by those skilled in the art that, as when prior art separator 2, support plate 70 ' (and therefore, all components in first fabric part and the second fabric part) remain by means of turbine shroud and to be in desired location relative to rotor case 4 ', after rotor case 4 ' and turbine shroud are fastened to and go up each other, support plate 70 ' is depressed into and adjoins with prone shoulder 148 ' by this turbine shroud。Support plate 70 ' is substantially by means of extending the threaded fastener clamp of four lobe 284 between rotor case 4 ' and turbine shroud 178 '。Along with threaded securing member is tightened and makes support plate 70 ' and shoulder 148 ' to occur to adjoin, result, the O-ring packing 262 at described shoulder 148 ' place is pressed in the recess 260 being associated, and the second spiral compression spring 130 ' is compressed by top axle bearing unit 50 '。

In the operation of the separator 2 ' improved, the jet of oil is directed on turbine wheel 136 ' by the nozzle (not shown) in turbine shroud, in order to revolving wormgear impeller on the direction that arrow 134 ' (see Figure 29 and 34) indicates。This rotation of turbine wheel drives rotor assembly to rotate up in the side of arrow 134 ' around the central axis 64 ' of rotor case 4 ' as entirety。In other words, rotating shaft 78 '；Upper rotor part dish 80 '；Stacking the 84 ' of separator disks 82 '；Fan disk 240；End plate 86 '；Splash guard dish 242；And the fan of combination and turbine unit 88 ' (that is, being collectively referred to herein as rotor assembly) as black box rotating in housing 4 ' and relative to described housing 4 ' and support plate 70 '；Housing insert 72 '；And turbine shroud rotates together。

Release from motor body and need the gas processed by separator 2 ' to be introduced into separator 2 ' via the fluid intake 8 ' at the top being arranged in rotor case 4 '。Arrow 68 ' instruction in Figure 34, inlet gas enters rotor case 4 ' along parallel with central axis 64 ' and conllinear direction, and flows through three grooves 66 ' in top axle bearing unit 50 ' before flow into the entrance 600 of rotor assembly through 12 spokes 116 ' of upper rotor part dish 80 '。The rotary motion of 12 spokes 116 ' also results in the lateral movement of the fluid between described spoke, because described fluid tangentially moves from the circular path of spoke 116 ', and is effectively outwards dished out towards the cylindrical wall of rotor case 4。Substantially, 12 spokes 116 ' give cylindrical motion on inlet gas。

Inlet gas is downward through the spoke 116 ', 126 ' of upper rotor part dish 80 ' and separator disks 82 ', and this gas laterally moves towards the cylindrical wall of rotor case 4 ' via the space 602 between adjacent separator disks 82 ', shown in the arrow 184 ' in Figure 34。By along this path, the direction of fluid stream changes more than 90 °。

It will be appreciated that the space 604 between the radially portion circumferential edge of adjacent separator disks 82 ' represents the outlet of rotor assembly jointly。

It will further be appreciated by those of ordinary skill in the art that oil droplet 186 ' tends to pool together and formed bigger dripping when they move through separator disks and are spilled on the cylindrical wall of rotor case 4 '。Once be received by described cylindrical wall, oil droplet 186 ' tends to travel down on support plate 70 ' under gravity。The most external circumferential edge of separator stacking 84 ' is spaced inward fully relative to the cylindrical wall of rotor case 4 ', in order to allow oil droplet to advance in the clear downwards on described support plate 70 '。O-ring packing 262 guarantees that oil droplet will not flow between support plate 70 ' and rotor case 4 '。

It will be appreciated by those skilled in the art that, due to the rotary motion of rotor assembly, the fluid pressure in rotor case 4 ' the peripheral edge place of support plate 70 ' and separator disks stacking 84 ' than the abutment wall 266 of housing insert 72 ' and top area element 268 and support plate 70 ' around region in bigger。Result, it is intended to exist and purify the gas cylindrical wall along rotor case 4 ' downwards and along support plate 70 ' flowing radially inward。This fluid stream tends to be pushed down on on the support plate 70 of lower section by isolated oil droplet along cylindrical wall, and then propels it through the aperture in the abutment wall 266 of housing insert 72 ' radially inward along support plate 70 '。This gaseous fluid stream is indicated (see Figure 34) by arrow 188 '。Gaseous fluid stream radially-inwardly moves through the upper surface of support plate 70 ' towards the central round orifice opening's edge in housing insert 72 '。This stream crossing support plate 70 ' tends to, towards bottom bearing unit 90 ', isolated oil droplet is pushed through support plate 70, and described oil droplet can pass bottom bearing unit 90 '。The fan blade 140 ' of the fan of combination and the rotation of turbine unit 88 ' tends to the static pressure reducing in turbine shroud (rotor case 4 ' is attached thereon during use) in the region of bottom bearing unit 90 ', in order to suction oil droplet is by bottom bearing unit 90 '。Fan blade 140 ' is then radially thrown into turbine shroud by described, and from turbine shroud, they can return to engine crankshaft housing。Meanwhile, the gaseous fluid flowing through support plate 70 ' is drawn up the center port by package case 72 ', in order to pass radially outwardly through between end plate 86 ' and fan disk 240。Then gaseous fluid can leave rotor case 4 ' by flowing through the part 211 of the described cylinder of valve cell housing 12 ', and this part 211 is sealingly connected to housing insert 72 ', and exports 10 ' through housing insert outlet 150 ' and rotor case。

With reference to accompanying drawing it will also be appreciated that, except flowing and the aperture in flowing through the abutment wall 266 of housing insert 72 ' on the upper surface of support plate 70 ', purify some in gas and flow to the part 211 of described cylinder via the alternative route between the upside of the downside of end plate 86 ' and the isolating roof parts 268 of housing insert 72 '。This alternative route is indicated by arrow 190 '。

It will be appreciated that as, in the separator 2 of prior art, there is on bearing unit useful lubricant effect by the oil stream of the bottom bearing unit 90 ' of the separator 2 ' improved。Top axle bearing unit 50 ' is by being naturally occurring in turbine shroud and being transferred up to the oily mist of top axle bearing unit 50 ' lubricate similarly by extending the longitudinal flow path 92 ' of overwinding rotating shaft 78 '。

Prior art ALFDEX?The separator 2 ' of separator 2 or improvement described above can include the alternative devices for rotating rotating shaft 78 ' as shown in Figure 35 of accompanying drawing。With reference to Figure 35, it will be seen that, the Pelton impeller turbine before described is replaced by brushless electric motor 380, and the rotor 382 of this brushless electric motor 380 is in the lower end of support plate 70 " lower section is fixed to rotating shaft 78 "。Electro-motor 380 shown in Figure 35 drives prior art ALFDEX?Separator 2。But, as will be understood by those skilled, the electrical motor driven shown in Figure 35 arranges that the separator 2 ' that may also be combined with improvement described above uses。

With reference to Figure 35, it will be seen that, the electro-motor 380 that electrical motor driven is arranged is arranged in the housing 384 being fixed on rotor case 4 by means of multiple threaded fasteners 180 ' (Figure 35 only show one of them)。Motor shell 384 is made up of upper part 386 and low portion 388, and they utilize suitable fastening means to be fixed on and go up each other, and has the O-ring packing 390 of seam between them。O-ring packing 390 prevents dirt, water and/or is arranged in other impurity outside housing 384 and undesirably leaks into the space of housing 384。By this way, electronic component (including printed circuit board (PCB) and/or other circuit) is kept apart with the material that may result in the damage to them and fault subsequently。

The upper part 386 of housing 384 is provided with the downward projection of cylindrical wall 392 limiting center port in described upper part 386。Cylindrical wall 392 is arranged in the separator assembled and rotating shaft 78 " positions with one heart。Deflection packing ring 139 " by back-up ring 404 " is maintained at rotating shaft 78 " on。Deflection packing ring 139 ' thus presses up against on the inner radial bearing race of bottom bearing unit, such as prior art ALFDEX?In separator 2。" having radial outer periphery edge, it is spaced radially apart with cylindrical wall 392, in order to allow contaminated oil from passing through between them for deflection packing ring 139。

The upper end of the other separate section 394 (having substantially Frusto-conical shape) of motor shell 384 is positioned at the lower end of the cylindrical wall 392 of upper part 386 and is sealed on this lower end。Sealing between cylindrical wall 392 and frusto-conically shaped portion 394 defines closed loop shape, and provides by means of other O-ring packing 396。The low portion 388 that the lower end (having the diameter bigger than its upper end) of frusto-conically shaped portion 394 abuts against motor shell 384 by means of another O-ring packing 398 seals。This sealing also defines closed loop shape。

Therefore, on the side of frusto-conically shaped portion 394, described part 394 and low portion 388 are consequently formed space, and electro-motor 380 is located therein, and rotating shaft 78 " lower end extend to wherein。On the opposite side of frusto-conically shaped portion 394, the remainder of described part 394 and upper part 386 and low portion 388 formed overall by around with the space/compartment 406 sealed, electronic/electrical gas component is (such as, printed circuit board (PCB) 408) contained therein, in order to electrical power and control signal are supplied to electro-motor 380。Compartment 406 not outside seal only with respect to motor shell 384 is opened, but also the space sealing being located therein relative to electro-motor 380 is opened。Therefore prevent the contaminated oil flowing through this space when using separator can close to electronic/electrical gas component and cause the damage to them。

Additionally, frusto-conically shaped portion 394 is provided with aperture (not shown), electric lead 410 (connecting motor 380 and described electric supply/control member) extends through this aperture and described wire is sealed on this aperture。

Adapter 412 also extends through the aperture 414 in motor shell 384, to allow one or more electric lead (not shown) to be positioned at the outside of separator (such as, it is associated for vehicle therein with separator), to be connected to the described electric supply/control member being contained in compartment 406。In other words, electric lead or multiple electric lead can be provided with for plug that is mechanically connected with adapter 412 and that electrically connect。This wire or multiple wire portability are used for electrical power and/or the control signal that electrical motor driven is arranged。Adapter 412 is sealed on housing 384, in order to prevent impurity from undesirably invading in compartment 406。

Although compartment 406 has the generally annular shape concentric with the rotor assembly of separator, it will be understood that, compartment 406 can have different shapes。

The stator 400 of electro-motor 380 is fixed to the low portion 388 of motor shell 384。With the aperture that the radial inner portion of the described frusto-conically shaped portion 394 that cylindrical wall 392 forms sealing defines the of substantially equal diameter of the inner most diameter with the stator 400 with electro-motor 380。

During the separator using the electrical motor driven being provided with Figure 35 to arrange, supply of electric power is connected to brushless electric motor 380, in order to operates its rotor 382 and thus makes rotating shaft 78 " rotates。As explained above, isolated oil transports through downwards bottom bearing unit 90 from rotor case 4。In the separator that the electrical motor driven being provided with Figure 35 is arranged, this isolated oil is discharged to the inside of motor shell 384 from bottom bearing unit, and is more particularly discharged in the space of the cylindrical wall 392 in upper case portion 386。The oil being then demultiplex out transports through the rotor 380 of electro-motor 380 and leaves motor shell 384 via the port 402 being positioned in lower housing section 388 below electro-motor 380。The operation of electro-motor 380 can not adversely be affected, because the electric lead of stator 400 is covered by one layer of epoxy resin varnish through rotor 382 (or through the space rotor 382 and stator 400) and the oil that comes in contact with described rotor 382 and stator 400。

Further relate to the manufacture of the separator 2 ' improved, and especially with regard to being assembled in rotor case 4 ' by top axle bearing unit 50 ', now Figure 37 of accompanying drawing to 41 is carried out reference。These figures show that the technique for being spun welded on rotor case 4 ' by top axle bearing unit 50 ' in following location: support plate 70 ' be assembled into lower end shoulder with rotor case 4 ' 148 ' adjacent time, this position is axially aligned with bottom bearing unit 90 '。Changing despite the geometry caused by the warpage of this rotor case 4 ' after the injection-molded by described housing 4 ', packaging technology has still ensured that axially aligning of top axle bearing unit 50 ' and bottom bearing unit 90 '。

This technique uses rotary welding clamp 500, and it includes stationary part 502 and the rotor portion 504 being rotatably mounted on stationary part 502。Stationary part 502 includes circular discs 506, and it has the diameter equal with support plate 70 '。The geometry of circular discs 506 so to such an extent as to allows described circular discs 506 to be positioned in the separator 2 ' assembled in the way of identical with support plate 70 ' and adjoins (as shown in Figure 40) with rotor case 4 '。Rotor portion 504 includes the center extending through circular discs 506 and the axle 508 being oriented orthogonal to described circular discs 506。Axle 504 is installed relative to circular discs 506 by means of bearing assembly (not shown)。

One end of axle 508 is provided with the head 510 for receiving top axle bearing unit 50 '。As concentric with the circular discs 506 of stationary part 502 and by rotor portion 504 rotate around axis centered by circular discs head 510 is provided。The diameter of head 510 is substantially equal to the diameter of the inner radial surface of the downward projection of cylindrical wall 58 ' of top axle bearing unit 50 '。By this way, the cylindrical wall 58 ' of top axle bearing unit 50 ' can be located at around head 510, wherein has little between top axle bearing unit 50 ' with axle 508 or does not have relative lateral movement。Relative rotary motion between top axle bearing unit 50 ' and axle 508 is prevented by the protuberance 512 erect from the circular discs of head 510。Head 510 includes three protuberances 512, and they mutually the same and around axle 508 rotation axiss are equally spaced。Protuberance 512 each has a part circular shape, and position and be sized to be positioned in the part circular groove 66 ' of top axle bearing unit 50 '。Protuberance 512 is basic identical with described groove 66 ' size and shape, and therefore, when protuberance 512 is received by described groove 66 (seeing Figure 37 and 38 especially), substantially prevent the top axle bearing unit 50 ' rotary motion relative to the head 510 of axle 508。

Second end in the distant place, one end being provided with head 501 of axle 508 is provided with for rotor portion 504 being connected to motor to drive the rotor portion 504 device 514 relative to the rotary motion of stationary part 502。

Having illustrated rotary welding clamp 500 in Figure 39 of accompanying drawing, this rotary welding clamp 500 has the top axle bearing unit 50 ' being positioned on its head 510。When top axle bearing unit 50 ' is positioned on head 510, axle 508 and top axle bearing unit 50 ' are inserted in rotor case 4 ', as shown in Figure 40。Circular discs 506 is positioned to the lower shoulder 148 ' of adjacent rotor case 4 '。More particularly, circumferential edge surface, radially portion 634 (formation datum level) registration of circular discs 506 becomes the cylindrical inner surface 632 with the lower open end around rotor case 4 ' to adjoin。By this way, it is determined that top axle bearing unit 50 ' is relative to the lateral register of rotor case 4 '。Utilizing the rotary welding clamp 500 being positioned at rotor case 4 ' by this way, the rotation axis of rotor portion 504 overlaps with the central axis 64 ' of the rotor case 4 ' described before。

Rotor portion 504 is arranged to move in the axial direction relative to stationary part 502, make top axle bearing unit 50 ' second position can be moved to from primary importance, in primary importance, described bearing unit 50 ' is spaced apart with the upper part of rotor case 4 ', in the second position, bearing unit 50 ' is forced into and adjoins (see Figure 34) with at the upper convex ridge 238 provided of rotor case 4 '。Top axle bearing unit 50 ' is being assembled into rotor case 4 ' upper period, rotor case 4 ' keeps fixing, and the lower shoulder 148 ' that the circular discs 506 of stationary part 502 is positioned to rotor case 4 ' adjoins simultaneously, rotor portion 504 rotates at a relatively high speed, and move further into vertically in rotor case 4 ', in order to make spin/rotate top axle bearing unit 50 ' contact with described convex ridge 238。The top axle bearing unit 50 ' of spin is pressed against convex ridge 238 forcefully, in order to produces frictional heat, and thus makes the abutment surface of the plastic material of top axle bearing unit 50 ' and convex ridge 238 melt。While extruding bearing unit 50 ' against convex ridge 238, the rotary motion of axle 508 promptly reduces and stops, in order to allowing bearing unit 50 ' and convex ridge 238 to be bonded to each other when melted plastic material cools down。Top axle bearing unit 50 ' and rotor case 4 ' are thus spun welded to be gone up each other。

Rotor case 4 ' can during spin-welding process by means of the lobe 284 extended in rotor case 4 ' and extend to cylinder installing rack 516 in threaded fastener and keep fixing (see Figure 40)。

After top axle bearing unit 50 ' is already affixed on rotor case 4 ', so that it may remove rotary welding clamp 500 from rotor case 4 '。Top axle bearing unit 50 ' thus keeps correctly positioning and being fixed on rotor case 4 ', as shown in Figure 41 of accompanying drawing。It will be appreciated that top axle bearing unit 50 ' is located relative to the lower circular shoulder 148 ' of rotor case 4 ' is in the position at center。Therefore, when the internals of separator 2 ' is positioned at housing 4 ', against the adjacent of described shoulder 148 ', support plate 70 ' ensure that bottom bearing unit 90 ' also medially positions about described shoulder 148 '。Although have after injection-molded rotor case 4 ' any before warpage, top axle bearing unit 50 ' and bottom bearing unit 90 ' are still axially aligned therefrom。

Compared with prior art separator 2, by means of its certain module/component (see Figure 36) that can exchange in different separator systems, the versatility of the separator of improvement is enhanced。It is hereinbefore described rotor case 4 ' (that is, a kind of certain types of module) and receives the ability of different valve cell 14 ' (that is, multi-form another type of module)。This modularity measure by multi-form given type, the module/component (such as, valve cell 14 ') with the same characteristic features for being connected with other module/component/engage realizes。By way of illustration, separator system can use the one in several multi-form valve cell potentially, even if because these multi-form being provided with allow in valve cell common feature of also mating with rotor case 4 ' when many other sides are likely to different。The table that Figure 36 provides shows how the different component/module of separator system can be optionally provided with component/module or exchange with multi-form component/module。

The invention is not restricted to particular embodiments described above。Alternative arrangement and suitable material reader for those skilled in the art will be apparent to。
