Description

SPIN-ON FILTER GASKET PROTECTION DEVICE FIELD OF THE INVENTION The present invention relates to a spin-on filter gasket protection device and a spin-on filtercomprising a spin-on filter gasket protection device and to a spin-on f1lter gasket protectionarrangement, and an engine and a vehicle comprising a spin-on filter gasket protection 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 filter mount 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. lt is very important that the surface on the filter mount arranged to abut against the filter gasket isfree from particles such as e. g. dirt etc. in order to avoid leaks between the gasket and the filtermount, this leading to fall in pressure in the fluid system in question and to pollution of theenvironment and surrounding components e.g. on a vehicle chassis. This problem is especiallyrelevant in applications where the spin-on filter in use is exposed to a environment containing dirtsuch as e. g. in the area surrounding the chassis of a vehicle when the filter is to be replaced afterhaving been exposed to dirt etc., and is traditionally addressed by carefully cleaning the surfaceon the filter mount after removal of the old filter but before mounting of a replacement filter thereon.

Figure 1 shows schematically a cross-section of a spin-on filter 2 and a corresponding filtermount 4 arranged on a device to which the spin-on filter 2 is to be attached during operation ofthe system containing the fluid 20 to be filtered by the spin-on filter, where the spin-on filter 2comprises a spin-on filter housing 6, the latter comprising a filter body 8 defining a mouth 10 andfurther possibly comprising a cover 12, where the spin-on filter 2 further comprises a filter element 14 disposed in the spin-on filter housing 6. The spin-on filter 2 is mounted on the corresponding filter mount 4 during operation, in this embodiment by that the spin-on filter 2comprises an internal thread 16, arranged to be brought into engagement with a corresponding external thread 18 on the filter mount 4. ln this embodiment, the cover 12 comprises at least one inlet opening and at least one outletopening for the fluid 20 to be filtered by the spin-on filter 2, but it is possible to arrange some orall of these openings on the filter body 8 instead if the mouth 10 is of such narrow dimensionsthat a cover 12 is not present. ln this embodiment, the central opening is the outlet opening 22 ofthe spin-on filter 2, and a number of inlet openings 24, 26 are arranged in the cover 12 radially outside of the central opening 22 in the cover 12. ln operation, when fluid 20 is carried through the spin-on filter 2, the fluid 20 is usually under apressure higher than the ambient pressure outside of the filter mount 4 and the spin-on filter 2.The above corresponding threads 16, 18 of the spin-on filter 2 and the filter mount 4 togetherform a seal preventing fluid from passing therethrough, thus forcing all of the fluid 20 flowing(see dashed arrows in figure 1) through the spin-on filter 2 to pass through the filter element 14.At least one gasket 28 is arranged between the spin-on filter housing 6 and the filter mount 4 inorder to prevent fluid 20 from leaking out therebetween during operation. The gasket 28 ispreferably fastened to the spin-on filter 2, preferably already at manufacture, and the spin-onfilter 2 is then surrounded by a wrapping (not shown) thus allowing for keeping it clean until thewrapping is removed just prior to the mounting of the spin-on filter 2 to the filter mount 4, tofacilitate ease of mounting. The gasket 28 could optionally be arranged separate from the spin-onf1lter 2. ln this embodiment, the surface 30 on the gasket 28 which surface 30 is arranged to abutagainst a gasket contact surface 32 on the filter mount 4 is preferably “moistened” by oil prior to the mounting to further enhance the sealing properties of the gasket 28.
