    Abstract: A filter element may include a tubular element, first and second end caps, each associated with an opposite end of the tubular element, filter media positioned around the tubular element and between the first and second end caps, a biasing element associated with the tubular element, and a retainer element positioned at a first end of the tubular element. The retainer element may include a retainer aperture including a central circular portion and two opposite lateral slots extending from opposite sides of the central circular portion, and two arcuate shoulder segments extending between opposite sides of the two opposite lateral slots. A full tab may extend a first axial distance from a bottom surface of one of the two arcuate shoulder segments at a circumferential position in between the two opposite lateral slots, and a partial tab may extend a second axial distance less than the first axial distance from a bottom surface of the other of the two arcuate shoulder segments at a circumferential position on an opposite side of the lateral slots from the full tab.

    Abstract: A center tube for use with a filter element comprises a unitary body having a standpipe that defines a length along the longitudinal axis and a central flow passage and a plurality of radially extending flow fins attached to the standpipe, the flow fins spaced axially from one another along the standpipe to define radial flow channels, wherein each of the fins further defines a first aperture between the fin and the standpipe, the apertures together defining a first outer axial flow passage and the standpipe defines a rectangular shape.

    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 assembly includes housing and a filter device disposed within the housing to define a circumferential cavity therebetween. The filter assembly further includes a bypass valve having a housing wall, multiple inlets and an outlet formed on the housing wall, and a valve member. A first end of the valve member is coupled to a valve seat and a second end of the valve member engages with the outlet of the bypass valve. The valve member is displaced from a first position to a second position when pressure of fluid in the circumferential cavity is greater than a biasing force of a spring, and wherein the valve member engages with the outlet port of the bypass valve against the biasing force of the spring in the first position and the valve member allows the fluid to flow into the hollow center tube in the second position.
