Abstract: A filter element includes a first end cap, a second end cap, and a ring of filter media disposed between the first end cap and the second end cap. The ring of filter media circumscribes a central cavity. The filter element also includes an air-bleed conduit axially extending through the central cavity. The air-bleed conduit includes a first portion integrally formed with the first end cap and a second portion integrally formed with the second end cap. The second portion is configured to fluidly connect to the first portion.

Abstract: One aspect of the disclosure provides a filter element including a first end cap, a second end cap, a ring of filter media and an annular seal. The first end cap defines a cylindrical collar that circumscribes a first central opening and includes a substantially planar first outer surface that extends radially outward from the cylindrical collar to an outer peripheral edge. The second end cap defines a second central opening substantially coaxial with the first central opening. The ring of filter media is disposed between the first end cap and the second end cap, and circumscribes a central cavity in fluid communication with the first central opening and the second central opening. The annular seal is disposed upon the first outer surface of the first end cap and around the cylindrical collar. The annular seal extends axially way from the first outer surface.

Abstract: A filter subassembly is disclosed. The filter subassembly includes an end cap connected to a ring of memory material. The end cap includes a tube-shaped body, a first ring-shaped body, a second ring-shaped body and a third ring-shaped body. The tube-shaped body is defined by an inner radial surface, an outer radial surface, a first axial surface and a second axial surface. The inner radial surface defines a passage extending through the tube-shaped body. The first ring-shaped body extends axially away from the first axial surface of the tube-shaped in a first axial direction. The second ring-shaped body extends axially away from a second axial surface of the tube-shaped body in a second axial direction that is opposite the first axial direction. The third ring-shaped body extends axially away from the second axial surface of the tube-shaped body in the second axial direction that is opposite the first axial direction.

Abstract: An air-filtration system is provided for use in a vehicle for delivering air to a helmet worn by a vehicle operator. The air-filtration system comprises an air intake in the form of a window scoop for drawing exterior air, an air duct assembly for delivering air from the air intake to the helmet worn by the vehicle operator, and an air filter assembly disposed in-line with the air duct assembly between the air intake and the helmet. The air filter assembly includes a catalyst member for converting carbon monoxide to carbon dioxide, and a particulate filter member.

Abstract: A spin-on type filter assembly for lubricating oil includes a cast aluminum housing which contains a replaceable annular filter element. The filter element is resiliently retained in the housing by compressing a gasket thereon with a threaded end cap which closes one end of the housing. The housing includes a unitary front end wall with a plurality of inlet ports surrounding an axially positioned outlet port. In order to provide a secure coupling with the engine, an externally and internally threaded steel stud is threadably mounted in the outlet port for threadably coupling with the engine.
