Abstract
A filter assembly includes a base and a filter cartridge supported on the base. The filter cartridge includes a filter element mounted within a cup-shaped housing having a circumferentially extending wall and an open end. In the preferred embodiment, a collar circumscribes the housing and includes a set of cooperating bayonet lugs which cooperates with a corresponding set of bayonet lugs on the base, permitting easy removal of the filter when the filter is changed by merely rotating the collar one quarter of a turn. In the alternate embodiment, the lugs are included within the housing itself and cooperate directly with lugs on the base.
