Description
OIL FILTER ARRANGEMENT
FIELD OF THE INVENTION
The present invention relates to an oil filter arrangement comprising a spin-on filter and a filtermount, and to an engine comprising an oil filter arrangement, and to a vehicle comprising an oil
filter arrangement, and a spin-on filter for an oil filter arrangement.
BACKGROUND OF THE INVENTION AND RELATED ART
Spin-on filters comprising a filter body defining a mouth, a filter element disposed in the filterbody, and a cover covering the mouth are widely used in e.g. engines and gear boxes as e.g. oilfilters or fuel filters etc. due to their simple yet reliable design and their easy attachment, removaland replacement. The cover comprises at least one inlet opening and at least one outlet openingfor the fluid to be filtered by the filter, where the fluid to be filtered is arranged to pass throughthe filter element on its way from the inlet to the outlet. The spin-on filter further comprisesmeans for attaching the filter to a filter mount on the device utilizing the filter, which meanscomprise a thread on the filter which thread is arranged to be brought into engagement with acorresponding thread on the filter mount. Usually, the spin-on filter comprises a first centralopening in the cover, the opening having an internal thread to be brought into engagement with acorresponding external thread on the filter mount. The corresponding filter mount thus usuallycomprises a corresponding central tubular member comprising said external thread on its outerperiphery. The cover further comprises at least one further opening, usually a number of furtheropenings, arranged on the cover between the central opening and the radial periphery of thecover. The filter mount comprises corresponding members, e.g. at least one opening and apossible cavity connecting said opening to the further openings in the cover when the spin-onfilter is mounted onto the filter mount. lf the central opening is the outlet opening from the spin-on filter, the further openings are inlet openings. The above threads together form a sealpreventing fluid from passing therethrough. To prevent fluid from leaking out between the filtermount and the filter, at least one gasket is arranged between the filter and the filter mount radially
outside of said further holes. Said gasket is usually arranged fixed to the filter, but may also be a
part separate therefrom.
ln modern vehicles it is preferred to use compact designs to save space, which can result in adesign where a spin-on oil filter can not be arranged to be mounted to a corresponding filtermount vertically from below, i.e. with the openings in the filter cover facing upwards, but insteadhas to be mounted e. g. vertically from above the same or horizontally from the side of the same,i.e. at an angle to the first mentioned position. This means that the oil in the oil filter will notremain therein when the engine is turned off but will instead begin to slowly flow back to the oilreservoir, e.g. an oil trough, via e.g. the crankcase, the flow speed being determined e.g. by thetemperature of the oil. Thus, when a spin-on oil filter on a vehicle with such a filter mount design
is to be replaced by removing the old filter and mounting a new filter in its place, oil will leak out
if the filter is removed soon after that the vehicle has been driven to the garage as the oil in the oil
filter takes some time to empty to the oil reservoir, more time if the vehicle has been parked for atime outside the garage waiting for its turn to be serviced. This will lead to oil possibly leakingout on the ground, the mechanic, or on possibly sensitive parts of the vehicle.
One way used for speeding up the emptying process mentioned above is to puncture the spin-onoil filter housing using e. g. a screw driver before removal which results in air entering the oilfilter facilitating the emptying of oil therefrom.
US 5,817,232 A and US 2011/0303604 A1 show spin-on filters.
SUMMARY OF THE INVENTION

DESCRIPTION OF PREFERRED EMBODIMENTS
The same reference numerals are being used for similar features in the different drawings.
Figure 1a shows schematically a cross-section of an oil filter arrangement 2 comprising a spin-onfilter 4 and a filter mount 6 according to a first embodiment of the invention in an operatingposition A and arranged on a device to Which the spin-on filter 4 is to be attached duringoperation of the system containing the fluid 8 to be filtered by the spin-on filter 4, Where the spin-on filter 4 comprises a spin-on filter housing 10, the latter comprising a filter body 12 defining amouth 14 and further possibly comprising a cover 16, Where the spin-on filter 4 further comprisesa filter element 18 disposed in the spin-on filter housing 10. The spin-on filter 4 is typicallygenerally cylindrical and can be rotated around a central aXis (the dashed line in Fig. la). Thespin-on filter 4 is mounted on the corresponding filter mount 6 during operation, in thisembodiment by that the spin-on filter 4 comprises an internal thread 20, arranged to be broughtinto engagement With a corresponding external thread 22 on the filter mount 6 by rotation of the
spin-on filter 4 around the axis of the spin on filter 4.
ln this embodiment, the cover 16 comprises at least one inlet opening and at least one outletopening for the fluid 8 to be filtered by the spin-on filter 4, but it is possible to arrange some orall of these openings on the filter body 12 instead if the mouth 14 is of such narroW dimensionsthat a cover 16 is not present. ln this embodiment, the central opening is the outlet opening 24 ofthe spin-on filter 4, and a number of inlet openings 26, 28 are arranged in the cover 16 radially r
outside of the central opening 24 in the cover 16.
ln operation, When fluid 8 is carried through the spin-on filter 4, the fluid 8 is usually under apressure higher than the ambient pressure P outside E of the filter mount 6 and the spin-on filter4. The above corresponding threads 20, 22 of the spin-on filter 4 and the filter mount 6 togetherform a seal preventing fluid from passing therethrough, thus forcing all of the fluid 8 floWing (seedashed arroWs in figure 1) through the spin-on filter 4 to pass through the filter element 18. Atleast one primary gasket 30 is arranged between the spin-on filter housing 10 and the filter mount
6 in order to prevent fluid 8 from leaking out therebetWeen during operation. The primary gasket
30 is preferably fastened to the spin-on filter 4, preferably already at manufacture, and the spin-on filter 4 is then surrounded by a Wrapping (not shown) thus allowing for keeping it clean untilthe Wrapping is removed just prior to the mounting of the spin-on filter 4 to the filter mount 6, tofacilitate ease of mounting. The primary gasket 30 could optionally be arranged separate from thespin-on filter 4. ln this embodiment, the surface 32 on the primary gasket 30 Which surface 32 isarranged to abut against a primary gasket contact surface 34 on the filter mount 6 is preferably“moistened” by oil prior to the mounting to further enhance the sealing properties of the primary
gasket 30.
A spin-on filter 4 may comprise one primary gasket 30 or multiple, preferably coaXially arranged,primary gaskets. Here is shoWn one primary gasket 30 only Which in case of multiple primarygaskets is to be interpreted to represent all primary gaskets 30. The primary gasket 30 is in thisembodiment shoWn arranged aXially X on the spin-on filter 4, but could also in anotherembodiment be arranged radially r on the spin-on filter (see e.g. the embodiment shoWn in
figures 7-8).
The oil filter arrangement 2 comprises a spin-on f1lter 4 and a filter mount 6, Where, When thespin-on filter 4 is mounted on the filter mount 6 in an operating position A (the positionschematically shoWn in figure l) Where at least one primary gasket 30 is arranged to provide afluid tight seal between the filter mount 6 and the spin-on filter housing l0, at least one oil inletopening 26, 28 arranged on the spin-on filter 4 is arranged to be in fluid connection With at leastone oil source opening 36, 38 arranged on the filter mount 6 and at least one oil outlet opening 24arranged on the spin-on filter 4 is arranged to be in fluid connection With at least one oildistribution opening 40 arranged on the filter mount 6, Where the filter mount 6 furthercomprises at least one oil drainage opening 42 arranged, in the operating position A, sealed offfrom the interior 44 of the oil filter 4 by the at least one primary gasket 30 and arranged, in theoperation position A and in a draining position (see figure 2), sealed off from the ambientatmosphere 46 by at least one secondary gasket 48, and arranged, in the draining position (seefigure 2) in fluid connection With the interior 44 of the oil filter 4. By this design, the oil 8 in theinterior 44 of the oil filter 4 of the oil filter arrangement 2 can thus be drained through the
drainage opening 42 in the filter mount 6 to such a degree that the oil spill from the oil filter 4 is
minimized when the oil filter 4 is disengaged from the filter mount 6, this regardless of in whichspace orientation (with the openings 24, 26, 28 in the oil filter 4 facing upwards, or downwards orat some position therebetween) the oil filter 4 is positioned when mounted on the filter mount 6 atthe time the oil filter 4 is to be removed from the filter mount 6. This is achieved by firstlyturning the oil filter 4 from the operating position A to a draining position B, thereafter Waitingfor oil to flow out from the interior 44 of the oil filter 4 in the draining position B, and finallyturning the oil filter 4 from the draining position B until the oil filter 4 is disengaged from the
f1lter mount 6.
ln this embodiment, the at least one secondary gasket 48 is arranged to the spin-on filter 4 in amanner of a “ring”. The at least one secondary gasket 48 is preferably, at least somewhat,flexible. The preferred fleXibility of the at least one secondary gasket 48 allows for press and sealagainst a surface 50 of the filter mount 6 when the at least one secondary gasket 48 arranged onthe filter housing 10 is pressed against the filter mount 6 while undergoing some flexibledeformation. The at least one secondary gasket 48 is preferably arranged to be pressed against thefilter mount 6 while undergoing flexible deformation when the spin-on filter 2 is in the operating
position A or in the draining position B.
ln this embodiment, the at least one secondary gasket 48 is integrated with the at least oneprimary gasket 30 to one unit, the parts of which unit can be of the same material or differingmaterials depending e. g. on the fleXibility and other properties desired for the different parts
thereof.
ln Figure 1b a view from the side of the spin-on filter 4 of Fig. 1a is shown. As is seen in Fig 1b,the cover 16 may e.g. be a substantially circular ringshaped object arranged outside of and aboutthe filter element 18 as shown in the figure, but other suitable shapes, such as e. g. the commonlyused circular wave-shape (not shown), are also possible for the cover 16. The secondary gasket48, here integrated with the primary gasket 30, is arranged radially outside the primary gasket 30.The secondary gasket 48 can be generally rotationally symmetrical. The secondary gasket 48provides a sealing between the spin-on filter and the filter mount 6. ln this embodiment the
primary gasket 30 and secondary gasket 48 are located with essentially no aXial displacement on
the spin-on filter. The primary gasket 30 is arranged to provide a sealing to the top part of thef1lter mount 6 in an aXial direction of the spin-on filter. The secondary gasket 48 is arranged toprovide a sealing to the inner lateral of an outer wall 50 of the filter mount 6 to prevent oil
leakage during mounting of the spin-on filter 4.
Figure 2 shows schematically a cross-section of an oil filter arrangement 2 comprising a spin-onf1lter 4 and a filter mount 6 according to figure 1 in a draining position B. As can be seen in thefigure when comparing with figure 1, when the spin-on filter 4 is mounted on the filter mount 6in an operating position (see figure 1) where at least one primary gasket 30 is arranged toprovide a fluid tight seal between the filter mount 6 and the spin-on filter housing 10, where atleast one oil inlet opening 26, 28 arranged on the spin-on filter 4 is arranged to be in fluidconnection with at least one oil source opening 36, 38 arranged on the filter mount 6 and at leastone oil outlet opening 24 arranged on the spin-on filter 4 is arranged to be in fluid connectionwith at least one oil distribution opening 40 arranged on the filter mount 6, where the f1ltermount 6 further comprises at least one oil drainage opening 42 arranged, in the operating position(see figure 1), sealed off from the interior 44 of the oil filter 4 by the at least one primary gasket30 and arranged, in the operation position (see figure 1) and in a draining position (a positionschematically shown in f1gure 2), sealed off from the ambient atmosphere 46 by at least onesecondary gasket 48, and arranged, in the draining position (a position schematically shown in
figure 2) in fluid connection with the interior 44 of the oil filter 4.
Figure 3a shows schematically a cross-section of an oil filter arrangement 2 comprising a spin-onfilter 4 and a f1lter mount 6 according to a second embodiment of the invention in an operatingposition A. This embodiment differs from the one shown in figure 1a in that the at least one
secondary gasket 48 is arranged “bowl shaped”.
ln Figure 3b the spin-on filter is seen from the side. As is seen in Figure 3a and 3b, the secondarygasket 48 is formed to follow the outer side of the filter housing for a distance thereof andcomprising a outer lip provided radially outside of the portion following the outer side of thefilter housing for closing a gap between the filter housing 10 and the filter mount 6 during
mounting of the spin-on filter 4. As is seen in Figure 3b, the secondary gasket 48, here integrated
11
with the primary gasket 30, is arranged radially outside the primary gasket 30. The secondarygasket 48 comprises a curved portion arranged to follow the lower part of the outer side of thespin-on filter. The secondary gasket also comprises a lip arranged in a radial direction from thecurved portion to contact the surface 50 of the filter mount 6. The secondary gasket 48 therebyprovides a sealing between the spin-on filter and the filter mount 6. ln this embodiment theprimary gasket 30 and secondary gasket 48 are located with some aXial displacement on the spin-on filter. The primary gasket 30 is arranged to provide a sealing to the top part of the filter mount6 in an aXial direction of the spin-on filter. The secondary gasket 48 is arranged to provide asealing to the inner lateral of an outer wall 50 of the filter mount 6 at some aXial distance from
the primary gasket 30 to prevent oil leakage during mounting of the spin-on filter 4.
Figure 4 shows schematically a cross-section of an oil filter arrangement 2 comprising a spin-on
filter 4 and a filter mount 6 according to figure 3 in a draining position B.
Figure 5a shows schematically a cross-section of an oil filter arrangement 2 comprising a spin-onfilter 4 and a filter mount 6 according to a third embodiment of the invention in an operatingposition A. This embodiment differs from the one shown in figure 1 in that the at least onesecondary gasket 48 is arranged separate from the at least one primary gasket 30, i.e. they areseparate units, the parts of which units can be of the same material or differing materials
depending e. g. on the flexibility and other properties desired for the different parts thereof.
ln this embodiment, the at least one secondary gasket 48 preferably has a central inner opening52 having an inner diameter, at least somewhat, smaller than the outer diameter of the spin-onfilter housing 10, the rim of the inner opening 52 of the at least one secondary gasket 48 thusbeing pressed against the outer surface of the spin-on filter housing 10 thus effecting an effective
seal between the secondary gasket 48 and the outer surface of the spin-on filter housing 10.
ln Figure 5b the spin-on filter is seen from the side. As is seen in Figure 5a and 5b, the secondarygasket 48 is formed as a separate gasket, separate from the primary gasket 30. As is seen in Fig5b, the secondary gasket 48, is arranged radially outside the primary gasket 30. The secondary
gasket 48 is generally formed by a lip arranged in a radial direction to contact the surface 50 of
12
the filter mount 6. The secondary gasket 48 thereby provides a sealing between the spin-on filter4 and the filter mount 6. ln this embodiment the primary gasket 30 and secondary gasket 48 arelocated with some aXial displacement on the spin-on f1lter. The primary gasket 30 is arranged toprovide a sealing to the top part of the filter mount 6 in an aXial direction of the spin-on filter.The secondary gasket 48 is arranged to provide a sealing to the inner lateral of an outer wall 50 ofthe filter mount 6 at some aXial distance from the primary gasket 30 to prevent oil leakage during
mounting of the spin-on filter 4.
Figure 6 shows schematically a cross-section of an oil filter arrangement 2 comprising a spin-on
filter 4 and a filter mount 6 according to figure 5 in a draining position B.
Figure 7a shows schematically a cross-section of an oil filter arrangement 2 comprising a spin-onfilter 4 and a filter mount 6 according to a fourth embodiment of the invention in an operatingposition A. This embodiment differs from the one shown in figure 5a in that the at least oneprimary gasket 30 is arranged radially r, not aXially X, on the spin-on filter 4, and in that the at
least one oil drainage opening 42 is arranged radially r, not aXially X, on the filter mount 6.
ln Figure 7b the spin-on filter is seen from the side. As is seen in Figure 7a and 7b, the secondarygasket 48 is formed as a separate gasket, separate from the primary gasket 30. As is seen inFigure 7b, the primary gasket 30 is arranged in a lateral direction to provide a sealing between theouter side of the spin-on filter housing and a first part of a filter mount surface. The secondarygasket 48 is arranged aXially displaced in relation to the primary gasket 30.
