ABSTRACT:
An engine induction air filter element and a positive crankcase ventilation breather element are combined into a single discardable cartridge which is received within an air cleaner housing in a vehicle induction air system. The induction air filter media is comprised of an array of pleats, the tips of which respectfully define the upstream and downstream planes of the filter. A sealant material circumscribes the perimeter of the downstream plane of the induction air filter, and the sealant material on one end thereof includes a projecting portion which supports the breather air filtering media on the one side of the induction air filtering media, with a gap therebetween which receives a partition which is a part of the air cleaner housing. The partition includes a flow restricting aperture, which is closed by the transverse surface of one of the end pleats of the induction air filtering media. Crankcase ventilating air passes through the breather element and then through the aperture, with any oil remaining in the air communicated through breather filter air element being entrained on the transverse surface of the end pleat.
