Definitions
- the present invention relates generally to filter elements and more particularly, to noncircular replaceable filter elements and systems including the same.
- Fuel filters are found in almost all modern internal combustion engines in one form or another.
- a fuel filter is a filter that is placed at some point in the fuel line and is designed to remove unwanted contaminates or particulates from the supply of fuel. If these contaminates are not removed before the fuel enters the engine, they can cause rapid wear and failure of such items as fuel pumps, injectors, and cylinders due to the abrasive action of the particles on high-precision components.
- Fuel filters also can improve performance of the engine, as the less contaminants in the fuel, the more efficiently it can be burned. In many potential engine system designs space constraints would not allow for a conventional circular filter element.
- One embodiment is a filter assembly wherein the shape of the filter is a non-circular geometry.

In the illustrated form,center post 314 protrudes up through secondfluid chamber 302 defined bycentral portion 108 ofhousing 102 and into firstfluid chamber 300 defined byupper portion 106 ofhousing 102.Center post 314 includeshollow interior 316 and at least oneaperture 318 located onupper portion 320 ofcenter post 314.Aperture 318 allows fluid that has been filtered byfilter media 204 to pass intohollow interior 316 ofcenter post 314.Lower portion 322 ofcenter post 314 includes an externally threadedsegment 324 that is used to securecenter post 314 to an internally threadedsegment 326 ofconnection member 308.Lower portion 322 ofcenter post 314 could be secured toconnection member 308 using various other connection methods. -
Filter cartridge 200 is fixedly secured inhousing 102 by placingaperture 216 offilter cartridge 200 onupper portion 320 ofcenter post 314 and forcingfilter cartridge 200 downwardly untilseal 218 oflower end plate 206 makes contact withupper portion 328 ofconnection member 308.Seal 218 provides a fluid tight seal betweenlower end plate 206 andcenter post 314. As illustrated,lower end plate 206 includes an upwardly extending circular shapedrib 330 that definesaperture 216 oflower end plate 206.Seal 218 is connected withlower surface 332 oflower end plate 206, outer surface 334 of therib 330, andupper surface 336 ofrib 330. As previously set forth,lower surface 336 oflower end plate 206 andlower surface 306 of lowermounting surface portion 110 define thirdfluid chamber 304. In alternative forms,center post 314 may include a connection member that provides a fluid tight seal withlower end plate 206. - As further illustrated in
FIG. 6 , thefilter cartridge 200 includes acentertube 340.Centertube 340 runs substantially parallel withfilter media 204 andhousing 102 along a vertical axis offilter assembly 100.Centertube 340 includes a plurality ofapertures 342 that allow fuel to pass into aninternal fluid chamber 344 offilter cartridge 200. Filtered fluid from internalfluid chamber 344 may then enterhollow interior 316 ofcenter post 314 throughapertures 318 incenter post 314. An upper surface oflower end plate 206 is connected with a lower end ofcentertube 340 and a lower surface ofupper end plate 202 is connected with an upper end ofcentertube 340.Filter media 204 is wrapped, positioned, or otherwise connected around or with the outside surface ofcentertube 340. -
Lid 104 is removably connected withupper portion 106 ofhousing 102. Oncefilter cartridge 200 is placed overcenter post 314,lid 104 may then be connected withupper portion 106 ofhousing 102. In one form,lid 104 includes an externally threadedsegment 346 that screws into an internally threadedsegment 348 ofupper portion 106 ofhousing 102. The externally threaded segment 246 oflid 104 is located onlower portion 350 oflid 104. The outside diameter oflower portion 350 oflid 104 is somewhat smaller than the inside diameter ofupper portion 106 ofhousing 102. - A
central portion 352 oflid 104 includes a retainingclip 354 and an upperinternal surface 356. Retainingclip 354 protrudes downwardly a predetermined distance from upperinternal surface 356. Aslid 104 is screwed intoupper portion 106 ofhousing 102,upper end plate 202 offilter cartridge 200 snaps or passes through retainingclip 354. Aslid 104 continues to be screwed intoupper portion 106 ofhousing 102,upper end plate 202 offilter cartridge 200 eventually makes contact with upperinternal surface 356 oflid 104.Center post 314 andlid 104 thereby cooperate with one another to securely holdfilter cartridge 200 within first and secondfluid chambers housing 102. In alternative forms,lid 104 may be secured toupper portion 106 ofhousing 102 using a quarter turn lid (bayonet), a friction fit, or the illustrated threading arrangement could be reversed. - A
seal 358 is positioned within a groove or notch 360 oflid 104 and is used to form a fluid tight seal between anoutside edge 362 oflid 104 and aninside edge 364 ofupper portion 106 ofhousing 102. Referring back toFIGS. 1-3 ,lid 104 includes a dome shapedcap portion 150 that includes a plurality of grippingmembers 152 protruding upwardly from the dome shapedcap portion 150. At the top of dome shapedcap portion 150 is atool attachment member 154. Grippingmembers 152 allow an installer to use their hands to begin to tightenlid 104 ontohousing 102 and after reaching a certain tightening point, a tool may be placed ontool attachment member 154 to further tightenlid 104 on to an upper edge 156 ofupper portion 106 ofhousing 102. - Referring to
FIG. 7 , a top cross-sectional view of a portion offilter media 204 offilter cartridge 200 is illustrated. As depicted,filter media 204 has apredetermined width 204 a and apredetermined height 204 b. In addition,filter media 204 has a non-circular shape, which is illustrated as being oval or elliptical shaped in this form. In one form, the oval size is such that the ratio ofpredetermined height 204 b in relation topredetermined width 204 a is 0.9 or less.Central portion 108 ofhousing 102 andcenter tube 340 have a similar size configuration as well as shape. - While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiments have been shown and described and that all changes and modifications that come within the spirit of the inventions are desired to be protected. It should be understood that while the use of words such as preferable, preferably, preferred or more preferred utilized in the description above indicate that the feature so described may be more desirable, it nonetheless may not be necessary and embodiments lacking the same may be contemplated as within the scope of the invention, the scope being defined by the claims that follow. In reading the claims, it is intended that when words such as “a,” “an,” “at least one,” or “at least one portion” are used there is no intention to limit the claim to only one item unless specifically stated to the contrary in the claim. When the language “at least a portion” and/or “a portion” is used the item can include a portion and/or the entire item unless specifically stated to the contrary.
