Abstract
Abstract A fluid filter and a method for attaching same to a filter mount (62) of an engine in sealing relation is provided. The fluid filter includes a filter media (54); a housing (52) for the filter media; complimentary interengageable locking devices (60) formed radially on the filter and filter mount for engaging the filter and the filter mount; and a seal (64) positioned between the housing and the filter mount. The locking devices include either: a first set of circumferentially spaced flanges (70) formed on the inner wall (72) of the housing and a second set of circumferentially spaced flanges (74) formed on the filter mount (62); or a plurality of bolts (110) attached to the filter mount (62) or a plate (116) attached to the housing (52) and a corresponding plurality of holes (114) formed in the plate or filter mount, respectively. The sealing means includes an annular, O-ring (75, 120, 150, 156, 170) positioned between the housing and the filter mount. The method includes the steps of: forming either of the above-described fluid filters; and either inserting the first set of flanges between the second set of flanges or, inserting each of the plurality of bolts into one of the corresponding plurality of holes, and turning the filter a quarter turn to engage the filter and the filter mount.
