With impingement area and the jet regulator of annular wall

Technical field

The present invention relates to a kind of jet regulator with jet regulator housing.

Background technology

This jet regulator is described in the German patent application 10 2,012 021 361.1 earlier And it is proved to.

In this jet regulator, water through-current capacity is proportional to the hydraulic pressure of existence, thus the most Jet regulator may be flow through when high pressure with possible too much water, that is water consumption becomes unfavorable.

Summary of the invention

Therefore, the task of the present invention is, creates a kind of jet regulator starting and limiting type, In this jet regulator, the advantage of the water jet of good inflation is possible, and higher The water yield excessive during pressure without flow through.

This task utilizes means as described below and feature to solve.

According to the present invention, the jet regulator feature with jet regulator housing that beginning limits Be, in the enclosure interior space of this jet regulator housing, be provided with orifice plate, this orifice plate with The through flow hole of multiple water for separately percolation, wherein, orifice plate has the collision of the atresia of central authorities Face, this impingement area is at least defined by the cincture of first annular wall, and first annular wall has multiple along footpath Orient to direction penetrates opening and in the side being arranged in impingement area plane penetrating opening On be respectively equipped with one with penetrate the through flow hole through orifice plate of open communication, and first annular Wall outer circumferential side by annular annular space around, it is characterised in that: the flow direction along water exists Impingement area upstream or be arranged over the throttling arrangement with through-flow openings and/or amount at impingement area Actuator, and impingement area has within first annular wall radially and between this first annular wall Second annular wall of the small diameter separated.

Therefore, the throttling arrangement being integrated in jet regulator or amount regulation are utilized according to the present invention Device opposing water consumption that is excessive or that improve, wherein, these devices can have known per se Structure, accordingly that is throttling arrangement and/or amount actuator have in terms of throughput restricted logical Cross opening.The water yield through throttling arrangement is throttled and the water yield of the amount of passing actuator is the completeest Entirely or to a great extent unrelated with the corresponding hydraulic pressure existed, thus hydraulic pressure corresponding with this The water yield independently generally remaining constant or the most not proportional to hydraulic pressure can pass.Joint Stream device correspondingly throttles the water yield, even and if measure actuator also can also be more when higher pressure Efficiently reduce or limit water consumption.

Throttling arrangement or amount actuator can have preliminary election or predetermined passing through by opening Cross section, should determine throttling action and/or in amount actuator by cross section in throttling arrangement Can by above, can by the sealing ring of hydraulic pressure deformation or O independently or automatically Ground is adjusted by throughput.This amount actuator is known per se and it is logical at this by opening The single opening arranged usually through multiple annulars is formed, and keeps lath between these single openings Extend, in an identical manner for throttling arrangement by opening in can also be this situation. Therefore, be there is the trend of the longitudinal central axis line annular substantially around jet regulator by opening, Thus on annulus, the current of distribution are possible the most equably.

Second annular wall can with streamwise by open downstream or by below opening, edge Radial direction is observed and is arranged on outside this on-axis projection passing through opening.

At this advantageously, the second annular wall has and multiple is arranged on impingement area spaced apartly Top radial penetration opening or have one be parallel to impingement area extend, can be by water overflow Top edge.

Therefore, the throttling arrangement arranged according to the present invention or amount actuator adjust in terms of its amount The water of joint can strike on impingement area, and then can fill the arranged according to the present invention Second ring wall is first until the height penetrating opening of the second annular wall or until the second annular wall Top edge height and owing to then the water of rear inflow arrive between said two annular wall Gap in and flow to penetrate opening there and neutralize and flow across first annular wall, thus Water arrives from both sides and penetrates opening and arrive therefrom in through flow hole and form uniform stream The jet gone out, this jet can mix with surrounding air.Even if here, when different hydraulic pressure The flow export of this jet regulator the most always obtain the most same or at least Obtain the water yield being throttled.

Water in order to flow into is shown greatly identical pressure as far as possible and is entered into the first of outside from both sides Annular wall penetrate in opening and then within these penetrate opening such degree by With so that this water generally vertically downward can be flowed out by through flow hole and be formed at very great Cheng Stream uniform, vertical, downwardly directed on degree, is positioned at the annular outside first annular wall empty Between can narrow partly in the trend of first annular wall at it so that the most relatively Narrow region and circumferentially direction, wider region are alternately.The water of the first annular wall of overflow can be by This is affected in terms of its amount and flowing velocity so that this water with desired pressure from the first ring The outside of shape wall enters into and penetrates in opening accordingly, this water strike there from this first Waterborne inside annular wall and with this from the water inside this first annular wall then commonly through Corresponding through flow hole flows downward out.

Here, a kind of form of implementation meeting purpose is it can be stated that in the outside of first annular wall On at least penetrating between opening or being arranged on all in being arranged on individually this first annular wall Penetrating in this first annular wall is provided with protuberance between opening, these protuberances are radially In reaching the annular space outside first annular wall and therefore form the annular space of this outside Narrow.

Annular space have in the region penetrate opening in this manner bigger width and with Time be positioned at these protuberances penetrating opening both sides can beneficially arrive outside annular space in Water towards the conveying penetrating opening.

For water uniform as far as possible transmission advantageously, described in penetrate opening and medially arrange Between two adjacent protuberances, and protuberance is distinguished with the opening that penetrates adjacent to protuberance Preferably there is identical distance.It is also advantageous that, all protuberances have consistent size and Shape.Because water has worked with having passed through throttling arrangement or amount actuator and annular thereof Be concentric with longitudinal central axis line to a great extent by opening arrive in jet regulator, so Provide following probability by features described above and measure, i.e. water also in each annular wall and The week of jet regulator it is evenly distributed in the most to a great extent when entering and penetrating in opening Upwards and water can arrive with the most consistent amount and penetrate in opening.Here, institute Have these measures mating reaction as follows, i.e. by throttling arrangement and extraordinarily by means of according to Even if the amount actuator that the present invention arranges and constructs can also limit when higher pressure flow through The water yield of jet regulator.

Protuberance on the outside of first annular wall can seamlessly or particularly single type ground It is connected with this first annular wall and the flow direction phase of the preferably axially water of direction and supply Instead exceed first annular wall.Thus, these protuberances contribute to making the first annular wall of overflow Water has been separated from and guides towards penetrating opening.

Meet purpose it may be that the element of blocking as the water for crossing first annular wall rises The described protuberance of effect the most about occupies width or the radial ruler of the annular space of outside Very little 1/3rd and on the end deviating from first annular wall of protuberance, preferably have rib Or rounding if desired.Therefore the protuberance being arranged in the annular space of outside can so set Meter so that be positioned at first annular wall both sides and enter into the water yield penetrating in opening substantially with Sample is big.

The water yield joined for good moisture and be adjusted to penetrating the conveying of opening advantageously, Compared with the coboundary penetrating opening in first annular wall, in the second annular wall with axle It is arranged on the lower limb of radial penetration opening above impingement area or (with the to distance One annular wall compares less diameter) top edge of the second annular wall is arranged on identical height Go up or get Geng Gao is set.This measure causes, and the radial direction flowing through the second annular wall from impingement area is worn The water of opening is with enough safeties and with enough amount spillings thoroughly, in order in order to the first ring Shape wall penetrate opening and therefore to the both sides of through flow hole enter and by this water with desired side Formula separately and stop inside impingement area to first annular wall the most direct Flowing.Can be reached from internal and penetrating from outside to first annular wall by described measure In opening and therefore to the more preferable balance of the flowing in through flow hole.

The lower limb penetrating opening in the second annular wall or the top edge of the second annular wall and/ Or the coboundary penetrating opening in first annular wall can meet destination and be arranged on one altogether With or in two parallel planes vertical with the longitudinal central axis line of jet regulator, also Extend in corresponding diametral plane the most point-blank.Targetedly may be used accordingly Separately and transmit with the water yield that will flow into.

It has been noted that be effective in the following way according to the second annular wall of present invention setting Efficiently, i.e. this second annular wall be radially provided through throttling arrangement or Outside the projection by opening of water saving aspect particularly efficient amount actuator.

Here, a kind of effectively and meet the form of implementation of purpose and can be: on amount actuator It is arranged on and is arranged on in axial direction being observed by the sealing ring in the groove of opening or O Above second annular wall, particularly it is parallel to this second annular wall and arranges, by opening to collision Within projection on face is arranged on the second annular wall, accommodate the groove of sealing ring or O at this The radial dimension of radial dimension the particularly greater than second annular wall and described be arranged on by opening In the most inwardly region more than the second annular wall of groove；Or groove together with sealing ring or O to the projection on impingement area and is arranged on the second ring by the projection on opening to impingement area Within shape wall.Particularly it is not important in latter alternative, the sealing ring within groove Or whether O abuts on the outer wall of groove in initial position and passes through opening the most more In internally positioned region, or on the contrary.Here, the sealing ring abutted on the outer wall of groove can There to be bigger effect, because the diameter of this sealing ring is the biggest and this sealing ring can To that be in inside, diameter is corresponding less by opening mating reaction.

By above-mentioned arrangement it is ensured that arrive the water jet of impingement area in the second annular Strike on this impingement area within wall and outside flowing can be carried out therefrom.Simultaneously by Can be according to this water yield of influence of hydraulic pressure and this water yield can be made at least to exist in sealing ring or O Largely independently keep identical big with this hydraulic pressure or at least can when using throttling arrangement Enough throttle this water yield.

Be located in the second annular wall penetrates opening and can be respectively provided with the border of side, these sides The border in face the most freely can terminate against the flow direction of the water of supply.Here, These radial penetration opening upwards in second ring wall can be crossed the downside of the amount actuator disposed Or the downside of the throttling arrangement disposed is closed.Therefore, amount actuator or throttling arrangement also may be used To obtain a kind of additional function, i.e. the radial penetration opening being defined in the second annular wall.

In order according to the jet regulator of the present invention this jet regulator at throughput actuator Even if or throttling arrangement is kept as also being able to when higher pressure produce when relatively small water is through-flow Giving birth to enough inflate and the soft water jet that bubbles accordingly, this water jet still looks like to the greatest extent may be used Can be bulky, meet purpose, at least one through flow hole in the orifice plate or all logical Discharge orifice at least in the bore section of outflow side towards outflow side conically or stairstepping expand.Logical Crossing this measure with particularly advantageous invention meaning, the water flowing through through flow hole can be with general conical Even if ground launches and actually whole at jet regulator housing when relatively small through-current capacity Can also mix with the surrounding air being inhaled in this jet regulator housing on housing cross-sectional Close.

Here, when at least one through flow hole at least in the bore section of outflow side towards through flow hole Outflow side the most conically expands so that from through flow hole discharge and by the list of tapered expansion Individual jet or beam in enclosure interior space the most still at single impinging jet at least one Through flow hole adjacent with at least one before being arranged on the melt injection part in enclosure interior space During single jet mixing, even if when the hydraulic pressure that little through-current capacity and throughput actuator reduce also Additionally be conducive to the good air mixing of the water of percolation.

Here, according to the present invention jet regulator another kind of structural form it can be stated that The collision inclined-plane that the outflow side of orifice plate and this orifice plate are provided around spaced apartly, this collision Inclined-plane makes clean housing cross-sectional streamwise in this region more and more narrow.Favourable at this In form of implementation, from through flow hole discharge and rich in the water spacer having air opened distance ground Orifice plate downstream or strike after orifice plate collision inclined-plane on, this collision inclined-plane additionally mixes And disperse the most ready water, the most so can be as all rich in the water having air Even, not splash but the soft water jet that bubbles is discharged from jet regulator.

Here, according to the present invention a kind of form of implementation that can particularly simple manufacture it can be stated that Collision inclined-plane forms the inflow side of following wall section, and this wall section constitutes or is configured at one The contraction flow region of undulate in vertical section.Here, collision inclined-plane is it is so structured that housing perisporium The protrusion forming part of inner circumferential side or the protuberance of inner circumferential side and with jet regulator housing or Person is connected with jet regulator housing component single type ground.

But a kind of embodiment, in this embodiment, collision inclined-plane is configured to embed To the annular of jet regulator housing or the wall section of the insertion of sleeve shaped.

In order at least one melt injection part can be embedded into the shell of jet regulator housing at this In internal portion and the amount actuator according to the present invention can be assembled simply, it is advantageous to penetrate That throttle regulator housing is configured to multi-piece type and there is at least two can be the most mutual The housing component connected.

If through flow hole in the orifice plate can be with one or the form of the most multiple concentric pore size distribution circle Arrange.Here, orifice plate has the impingement area of the atresia of already mentioned central authorities, this impingement area quilt Each annular wall is around defining.

Here, turn in the region of each annular wall and particularly outside first annular wall First water be decelerated, towards side deflection and by the part stream flowed into the most in opposite directions And mix, then this water can flow through orifice plate through flow hole and can on the outflow side of orifice plate Discharge with the form of the spray cone of respective numbers.Here, this point can also to a great extent with The pressure of the water flowed into reaches the most in the following way, i.e. according to the present invention at impingement area With the first annular wall amount of being arranged over actuator.

In order to make to mix also with surrounding air in the enclosure interior space of jet regulator housing And the water eddied accordingly is configured to always penetrate uniformly on the outflow side of jet regulator again Stream, and in order to make from the water of jet regulator discharge the uniforming device of outflow side May enter into different pressure from water and arrange while jet regulator is independently configured to not splash The water jet gone out, meets purpose, and the outflow side end face of jet regulator housing is tied by net Structure and honeycomb texture are formed, and formed the web frame of outflow side end face or honeycomb texture or with Jet regulator housing unremovably connect and/or particularly single type ground one-body molded or Formed by the imbedding piece being embedded in jet regulator housing.If here, and because According to the present invention along water flow direction impingement area upstream or above impingement area to have described that The mode amount of being provided with actuator, the most already mentioned effect of total melt injection to flowing out can Pressure with the water flowed into independently realizes in an advantageous manner.

Detailed description of the invention

Below in each embodiment of explanation, even if at the consistent parts of its function aspects in moulding Also consistent reference is obtained during change.

One entirety with the jet regulator of 1 labelling with common form and substantially with patent Shen Please have a jet regulator not being shown in further detail similarly by DE 10 2,012 021 661.1 Housing or be coupled in such jet regulator housing, this jet regulator housing is Jet regulator is fixed on water out and can have external screw thread or in order to be regulated by jet Device is fixed in the parts stretched out can have female thread.

According to Fig. 1 and 5, being provided with an orifice plate 5 in enclosure interior space, this orifice plate is with many Individual that can be seen that in FIG, that be extends in the vertical direction, water through-flow for separately percolation Hole 6.Here, orifice plate 5 has an impingement area 14 central, atresia, an outside First annular wall 15 is concentric with this impingement area and extends, and this first annular wall has multiple radially side To that orient and run through first annular wall 15 according to Fig. 1,4,5 and 6 whole cross section Penetrate opening 16.

The side being arranged in impingement area plane penetrate opening 16 is provided with respectively with these Through flow hole 6 that penetrate opening 16 connection, that run through orifice plate 5.Here, first annular wall 15 Outer circumferential side by an annular annular space 29 and one single type in the present embodiment with Orifice plate 5 connect inflow side housing component 26 around.

According to Fig. 1 and 2, along the flow direction of water in impingement area 14 upstream or on impingement area Side be provided with an entirety with 30 labellings, being adjusted by the amount of opening 31 with an annular Joint device, should meet destination by opening and interrupted by lath and thus remain at together.This leads to Being arranged on by cross section and one of current that cross opening 31, that cause substantially annular Sealing ring 32 square, that can deform by hydraulic pressure or the such mating reaction of O so that logical Cross this sealing ring 32 due to the deformation of hydraulic pressure can reduce by opening 31 by cross section, Thus can independently or automatically limit when higher hydraulic pressure and adjust throughput, despite This higher hydraulic pressure.

In order to form water jet that visually bubble, large volume, exist according to Fig. 1 to 6 at this Orifice plate 5 is provided with second annular wall 33 around impingement area 14, this second annular wall position In by below opening 31 and coaxially and radially with first annular wall at interval along footpath Outside direction is positioned at this on-axis projection passing through opening 31, within this first annular wall 15, And therefore there is the diameter less than first annular wall 15.Additionally, this second annular wall 33 There is the diameter bigger by opening 31 than the annular being arranged on above impingement area 14.

This second annular wall 33 that diameter is less has penetrating out of radially arranging equally Mouthfuls 34, as especially clearly can be seen that in Fig. 1,3 and 4, these penetrate opening at this with Its lower limb 35 has a segment distance from impingement area 14, and therefore its lower limb 35 is arranged on collision Above face 14.Therefore, when the water flowed into reaches this lower limb 35, this water is penetrated by these Opening 34 radially arrives the gap between first annular wall 15 and the second annular wall 33 In.

The most in figure 3 to be concentric with this from upper direction impingement area 14 and said two obliquely The visual angle of the annular wall 15 and 33 that ground is arranged is found out, at the peripheral hardware of bigger first annular wall 15 Although there being an annular space 29 the most ringwise, but this annular space at it around The trend of one annular wall 15 narrows partly so that the narrowest and the most again Circumferentially direction, wider respective regions is alternately.Here, wider region is separately positioned on radially The opening 16 that penetrates of orientation is located at the place at place on this first annular wall 15.In order to realize this Point, on the outside of first annular wall 15, is arranged in first annular wall 15 all these Penetrate and between opening 16, be provided with protuberance 36, these protuberances radially extend outward into In annular space 29 and therefore form narrow and the difference of the annular space 29 of this outside From the adjacent opening 16 that penetrates, there is identical distance.Penetrate opening 16 therefore the most medially It is arranged between two protuberances 36 adjacent, that there are consistent shape and size itself.

Here, these protuberances 36 on outside first annular wall 15 are seamlessly and preferably one Be connected with this first annular wall to part formula, and in axial direction with the flowing side of water of supply To the most nearly with first annular wall 15 relative to impingement area 14 and the bottom of annular space 29 The bulge quantity on border exceedes first annular wall 15.

Additionally, these are as the elements act of blocking of the water for crossing first annular wall 15 Protuberance 36 the most about occupies the radial dimension of annular space 29 or the three of width / mono-and in the present embodiment in the end deviating from first annular wall 15 of these protuberances On be configured to have rib but can also be rounding equally.Here, the bottom side of these protuberances Border is configured to circular arc equally as superposed parallel end edge circle, wherein, and phase In the minds of the center of curvature of the circular arc answered is arranged in impingement area 14 that is jet regulator 1 Imaginary axis through in place.The each circle carried on the back on excentric edge at protuberance 36 Therefore segmental arc is concentric with annular wall 15 and 33 and arranges and in the upper bound, side deviating from each annular wall Fixed corresponding cylindrical section is as the vertical edge interface of these protuberances 36.

Particularly by Fig. 4 but find out the most in FIG, in the second annular wall 33 with The lower limb 35 being arranged on the radial penetration opening 34 above impingement area 14 away from ground is disposed above The coboundary 37 penetrating opening 16 in first annular wall 15.By the second internal annular This most unbroken shape of wall 33, first the water of inflow must reach certain height, so After this water can be radially inwardly directed to side flow out.Thus stop from inboard to first annular wall 15 In the direct flowing penetrated in opening 16, thus the water of the also first annular wall of part overflow 15 Can be the most not only from internal but also be externally entering and penetrate opening 16 In and then by each flow direction and mobilization force mutually neutralize generally perpendicularly to enter Enter in through flow hole 6 and flowed out by these through flow holes.

Here, also find out at above-mentioned figure, penetrate opening 34 in the second annular wall 33 Lower limb 35 also has the coboundary 37 penetrating opening 16 in first annular wall 15 to be arranged on In two parallel planes vertical with the longitudinal central axis line of jet regulator 1 and flatly Extend.It is also recognized that they are arranged in a common plane and are just in identical height On degree.

Be located in the second annular wall 33 penetrate opening 34 be respectively provided with straight line, axis parallel The side boundaries 35a that ground extends, these side boundaries according to Fig. 3 and 4 against the water of supply Flow direction the most freely terminates, but the amount regulation being positioned on these ends according to Fig. 1 The downside of device 30 is the most upwards closed.Therefore, by with impingement area 14, annular wall 15 and 33 That formed with the orifice plate 5 of annular space 29 and closure wall 38 in outside cincture, This housing component 26 of inflow side can relatively easy and low price ground particularly single type ground manufacture.

Amount actuator 30 is arranged on by the sealing ring 32 in the groove 39 of opening 31 Can be preferably O, in axial direction observe up and the most coaxial according to Fig. 1 In the second annular wall 33, arrange with being parallel to this second annular wall.Here, but accommodate sealing ring The radial dimension of this groove 39 of 32 is more than the radial dimension of the second annular wall 33 and described logical Cross opening 31 be positioned at groove 39 the most inwardly more than that region of the second annular wall 33 In.Annular meets destination by multiple single by arrange each other on circle by opening 31 Opening is formed, should be by the diameter of opening thus less than the internal diameter of the second annular wall 33.The most true Protect, be threaded through opening 31 and arrive the water on impingement area 14 and only enter within the second annular wall 33 Enter.

The most then water can cross the lower limb 35 penetrating opening 34 of the second annular wall 33 Arrive in the gap between said two annular wall and partially across externally-located first Annular wall 15 arrives in the annular space 29 of outside, and in both sides in the way of having been described above Enter into outside first annular wall 15 penetrates in opening 16 and arrives downwardly directed leading to Discharge orifice 6, wherein, enters into the current penetrated opening 16 and penetrates opening 16 at these from both sides Inside in meet and thus reach down in through flow hole 6.

Fig. 1,4 and 5 are found out, at least one through flow hole 6 of orifice plate 5, according to Fig. 1 and 5 all of through flow holes 6 at least in the subregion of an outflow side towards its outflow side taper Ground expands.It is also contemplated that step-like expansion.

The through flow hole 6 being located in orifice plate 5 specifies for separately wearing in all embodiments illustrated The water of stream.By the water discharged from orifice plate 5 preferably in the whole length of through flow hole 6 upper conically Launch, though this water at little through-current capability and low hydraulic pressure (as these are also by amount actuator 30 in this region formed) time can also actually on the whole cross section of jet regulator with The surrounding air mixing being inhaled into.

Here, through flow hole 6 conically expands so that from through flow hole 6 discharge and by cone Shape expand water jet in enclosure interior space still at each single impinging jet to being arranged on housing The single jet of through flow hole 6 adjacent with at least one before on melt injection part in inner space Mixing.

Turn to enter into from both sides with water by water already mentioned flowed into and penetrate opening 16 In, the water of this inflow slows down and narrowing due to through flow cross section in the region of through flow hole 6 And again accelerate in each through flow hole 6.According to Bernoulli equation, improved in hole by this speed Produce negative pressure on the outflow side of plate 5, jet can be drawn ambient air into by this negative pressure and adjust In the enclosure interior space of joint device 1.The housing perisporium of the housing component 27 of outflow side sets for this Having fill opening 17 (Fig. 2), surrounding air can be entered by these air openings and can Taken away together by water.

Here, find out the most in figures 1 and 5, at the outflow side of orifice plate 5 and this orifice plate Being provided with the collision inclined-plane 19 of a cincture, this collision inclined-plane makes in this region spaced apartly Clean housing cross-sectional streamwise more and more narrow.This collision inclined-plane 19 forms the wall of annular The inflow side of section, this wall section be configured at least one along the longitudinal direction in vertical section in ripple The contraction flow region of shape wave.There is the wall section on collision inclined-plane 19 be configured to one here and can be embedded into and penetrate Annular in throttle regulator housing or the insertion 20 of sleeve shaped.

In a kind of unshowned form of implementation, collision inclined-plane 19 can be one-body molded with single type ground In the housing inner circumferential of the housing component 27 of outflow side.And illustrate and specify in an embodiment, orifice plate 5 single type ground are one-body molded in the enclosure interior space of the housing component 26 of inflow side.Jet is adjusted Joint device housing therefore it is so structured that multi-piece type and there is at least two can be the most detachable The interconnective housing component 26 and 27 in ground.

Shown in Fig. 1,2 and 5, according to the end face of outflow side of the jet regulator of the present invention Formed by a web frame or honeycomb texture 22, and form the web frame of the end face of outflow side Or honeycomb texture 22 is unremovably connected with the jet regulator housing component 27 of outflow side and spy It not that single type ground is one-body molded.But this web frame or honeycomb texture can also be embedding by an energy The imbedding piece entered is formed.

The web frame of the end face of the outflow side of formation jet regulator or honeycomb texture 22 are according to figure 1,2 and 5 being formed by lath 25, these laths are at least in the subregion of an outflow side In tapered according to Fig. 1 streamwise.

In a word, jet regulator 1 be configured to inflation jet regulator, as already mentioned, The jet regulator of this inflation has fill opening 17, and these fill openings are in the outflow of orifice plate 5 Side be passed through in the inside of jet regulator housing and these fill openings by enclosure interior space with Atmosphere.

According to the embodiment of Fig. 5, actually illustrate that shape is consistent with Fig. 1 with arrangement All details and parts.Comprise the explanation relevant with this and the figure of each reference in Figure 5 The explanation of 1 is consistent.Unlike Fig. 1, along the flow direction of water on impingement area 14 Swim or replace above impingement area an amount actuator 30 to be provided with a throttling arrangement 300.? This, this throttling arrangement 300 is formed as follows, i.e. do not comprise sealing ring in groove 39 32 or O, thus water can arrive impingement area 14 by this groove 39 with by opening 31. Flowing the most therefrom in the way of having been described above towards penetrating opening 16 and through flow hole 6 continues.

Find out the remodeling of orifice plate 5 in figure 6.Here, the second annular wall 33 is not to have and touch That hits that face 14 arranges spaced apartly penetrates opening 34, but the most upwards by one Edge 350 defines, and this top edge is effectively equivalent to according to Fig. 3's and 4 in its function aspects The lower limb 35 penetrating opening 34 of embodiment.Therefore, top edge 350 is relative to first The coboundary 37 penetrating opening 16 in annular wall 15 has identical position, that is this top Therefore edge can be arranged on a consistent plane or be arranged in a higher plane.
