Abstract
A filter element for use in a pan, such as a oil pan for a vehicle transmission or internal combustion engine, is configured for positioning in the opening of a sump in the pan. In order to position the filter element, an inwardly projecting shoulder is provided on the wall of the sump upon which a shoulder on the frame of the filtering elements rests. Between the two shoulders a resilient seal is positioned and held compressed by a latching arrangement on the filter element. A preferred latching arrangement comprises plurality of detents that project laterally from the filter element frame and seat within indentations in the wall of the sump. Preferably, the filter element has a pleated filter media.

A filter element for use in a pan into which is drained a recirculating fluid, wherein the filter element is disposed between a main collection chamber and a sump, the sump being defined by a vertically extending wall and a floor, an inwardly projecting shoulder on the wall of the sump, the shoulder being spaced from the floor of the sump, the filter element comprising:
- a frame having an upper portion and a lower portion, the upper portion having a downwardly facing shoulder extending laterally beyond the lower portion for supporting the filter element on the lower inwardly projecting shoulder;
- a vertically extending peripheral surface extending upwardly from the shoulder and surrounding the upper portion of the frame;
- a latching arrangement on the vertically extending peripheral surface for latching with a complementary latching arrangement on the sump wall;
- a gasket disposed between the downwardly facing shoulder on the frame and the inwardly projecting shoulder of the sump for sealing the frame with respect to the housing when the latching arrangement on the frame latches with the complementary latching arrangement on the sump wall;
- a filter media disposed within the frame and sealed where it contacts the frame.
