Fluid filter and method for attaching same in sealing relation to a filter mount

A fluid filter for attachment to a filter mount, comprising:

• (a) a filter media;
• (b) a housing for the filter media;
• (c) complementary interengageable locking means formed radially on the filter housing and the filter mount for engaging the filter housing and the filter mount, including a plurality of first members formed on the inside of the filter housing and a plurality of second members formed on the filter mount,
• wherein the plurality of first members includes a first set of circumferentially spaced flanges formed on an inner wall of the filter housing,
• wherein the plurality of second members includes a second set of circumferentially spaced flanges formed on the filter mount, and
• wherein each of the plurality of first members combines with a corresponding one of the plurality of second members to removably engage the filter housing relative to the filter mount;
• and
• (d) sealing means positioned circumferentially between the filter housing and the filter mount for creating a fluid seal therebetween, the sealing means being an annular O-ring positioned between the inner wall of the filter housing and the filter mount interior thereof,
• wherein the sealing means further comprises a flexible, annular member positioned between the inner wall of the filter housing and the filter mount interior thereof which is movable between a first, non-sealing position and a second, sealing position when the O-ring is under pressure.

A method for attaching a fluid filter to a filter mount of an engine, comprising the following steps:

• (a) forming a fluid filter having--
• (i) a filter media;
• (ii) a housing for the filter media, consisting essentially of a substantially cylindrical side wall, a first closed end and a second, open end,
• (iii) complementary interengageable locking means formed radially on the second open end of the filter housing and the filter mount, including a plurality of first members formed interiorally of the filter housing and a plurality of second members formed on the filter mount, and
• (iv) sealing means positioned circumferentially between the cylindrical side wall of the filter housing and the filter mount;
• (b) forming the plurality of first members as a first set of circumferentially spaced flanges fixedly attached to the inside of the cylindrical side wall of the filter housing and the plurality of second members as a second set of circumferentially spaced flanges on the filter mount;
• (c) inserting the first set of flanges between the second set of flanges;
• and then
• (d) turning the filter housing in a first direction relative to the filter mount to interengage the complementary locking means by combining each of the plurality of first members with a corresponding one of the plurality of second members to removably engage the filter housing and the filter mount with a seal formed between the cylindrical side wall of the filter housing and the filter mount.
