Abstract: A flow cap may include an outer ring, an inner ring, an inlet portion, and an outlet portion. The inlet portion may include first portions of the outer and inner rings, and a plurality of arms extending between the first portions of the outer and inner rings, wherein the arms at least partially define an inlet aperture configured to provide flow communication between an inlet port of a filter base and an interior portion of a filter element. The outlet portion may include second portions of the outer and inner rings, and a plate including an outlet aperture providing flow communication between an outlet port of the filter base and an exterior portion of the filter element. The outlet portion may also include a wall, wherein the plate and the wall prevent flow communication between fluid entering the inlet portion and fluid entering the outlet portion.

Abstract: A filter element may include a first end cap including an end cap barrier including an inner end cap aperture and end cap flow passages configured to provide flow communication between the of interior the filter element and the exterior of the filter element. The filter element may also include a first tubular member having a first end coupled to the first end cap to provide flow communication between the inner end cap aperture and a second end of the first tubular member. The filter element may further include first filter media extending around the first tubular member, an intermediate barrier coupled to a second end of the first tubular member, and second filter media having different filtering characteristics than the first filter media. One of the first filter media and the second filter media may include a coalescing-type media configured to promote separation of a first fluid from a second fluid.

Abstract: A filter element may include a tubular element defining an internal space, and a retainer element associated with a first end of the tubular element, wherein the retainer element is configured to be coupled to a first housing. The filter element may also include a valve seat member in the internal space. The valve seat member may include a valve seat aperture configured to provide a fluid seal with a valve poppet. The filter element may further include first and second end caps associated with ends of the tubular element. The filter element may also include filter media around the tubular element, and the second end cap may be configured to provide a fluid seal between the filter element and a drain passage in a second housing, such that as the filter element is separated from the second housing, fluid flows from the filter element into the drain passage.

Abstract: An end cap for a filter element may include an element receiver configured to be coupled to a tubular member, and a base passage receiver in flow communication with the element receiver. The end cap may further include an end cap barrier extending outward from the base passage receiver, the end cap barrier including a first side configured to face a filter base. The end cap may also include end cap flow passages configured to provide flow communication between filter media and a filter base, and including a passage opening spaced a first distance from the first side. The end cap may further include a barrier edge and a peripheral seal, wherein an uppermost surface of the peripheral seal terminates a second distance from the first side of the end cap barrier, wherein the first distance is greater than the second distance.

Abstract: A filter assembly may include a canister and a filter element received in the canister. The filter element may include filter media configured to promote separation of a first fluid from a second fluid having different characteristics than the first fluid as fluid passes through the filter media. The filter element may further include a first end cap, a second end cap, and a tubular member extending between the first and second end caps. The filter assembly may further include a flow cap associated with the first end cap of the filter element. The flow cap may include an inlet portion configured to provide flow communication between an inlet port of a filter base and the tubular member of the filter element, and an outlet portion configured to provide flow communication between an outlet port of the filter base and an exterior portion of the filter element.
