Abstract
A filter/oil pan assembly for use in devices such as transmissions for vehicles and for use as oil pans in internal combustion engines includes a housing having an upper chamber and a sump, wherein a filter element is disposed between the upper chamber and the sump. The filter element includes a filter media having pleats which extend in the direction parallel to the direction of movement of the vehicle utilizing the filter element. In order to facilitate flow through the filter element, all interior surfaces of the housing slope toward a well in which the filter element is positioned and the filter element itself has laterally projecting flanges which slope downwardly toward the filter media.
