International Classification:

F02B 2506

US Classification:

123572

Abstract:

A diesel engine crankcase ventilation filter is provided by a flat low profile filter housing extending in a horizontal plane and having an upper planar horizontal surface, a lower planar horizontal surface, and side surfaces extending between the upper and lower surfaces. A planar horizontal flat panel filter element extends parallel to the upper and lower surfaces. The housing has an upper plenum between the flat panel filter element and the upper surface, and a lower plenum between the flat panel filter element and the lower surface, an inlet receiving oil and air from the diesel engine and supplying same along an inlet path to the upper plenum to flow downwardly through the flat panel filter element to the lower plenum, a first outlet outputting air along a first outlet path from the lower plenum, and a second outlet outputting oil along a second outlet path from the lower plenum.
