Oil filter structure

摘要

An oil filter (10) includes a magnetic filtering device disposed inside the canister of the filter. The magnetic filtering device (26) includes a pair of oppositely arranged particle collection members (36) each having a recess in contact engagement with each other so as to define a ring space to secure therein a ring magnet (38). Each of the particle collection members (36) has a plurality of particle collection slots formed thereon and located in close proximity of the magnetic poles of the ring magnet (38). A top member is mounted to the upper one of the particle collection members to define an upper oil path and a base member (28) is mounted to the lower one of the particle collection members (36) to support the magnet (38) in position and define a lower oil path for conduction of the oil through the particle collection slots of the upper and lower particle collection members to have ferrous metal particle carried by the oil attracted and collected within the particle collection slots of the upper and lower particle collection members. <IMAGE>
