Abstract:
A panel shaped filter element adapted to seat on a sloped peripheral surface of a sump of an oil pan for filtering oil which flows in a selected horizontal direction in the oil pan toward the sump, comprising:a pleated filter media having first and second edges and first and second ends, the pleated filter media being folded to define only upstream and downstream peaks connected by substantially flat panels, the upstream peaks laying in a first plane to define a filter inlet face and the downstream peaks laying in a second plane to define a filter outlet face; the upstream and downstream peaks having parallel troughs therebetween, the troughs having the terminuses at the first and seconds ends of the filter media and extending in the direction of oil flow when mounted in the oil pan; a frame for supporting the filter media, the frame having first and second side plate portions for engaging and sealing the terminuses of the troughs; the frame further having laterally extending flanges disposed above the filter inlet face, each flange having an upper first planar surface sloping downwardly and inwardly toward a center of the filter inlet face forming a concavity around the filter inlet face for directing oil to be filtered toward the inlet face and each flange having a lower planar face that is substantially parallel to said upper first planar surface adapted for sealing with the sloped peripheral surface of the sump when the troughs are oriented to extend in the direction of oil flow.
