Abstract: A replaceable filter element for use with a filter assembly having a housing with a cover and a support core therein. The filter element has a ring of filtration media and an end cap at each end sealingly bonded to the filtration media. The second end cap has a central opening along the central axis of the filter element for receiving the support core. The first end cap also has a central opening along the central axis of the filter element. The central opening of the first end cap has a smaller diameter than the central opening of the second end cap. The central opening of first end cap is bounded by an annular flange integral with the first end cap and projecting axially inward a short distance from the first end cap toward the second end cap and terminating at a point closer to the first end cap than the second end cap. The annular flange is spaced radially inward from the ring of filtration media.

Abstract: A filter assembly has a housing open at one end, with an annular filter media/core assembly disposed in the housing. An end plate having at least two inlet openings and an outlet opening is disposed in the open end of the housing. The end plate is affixed to a lid which is secured to the end of the housing. A combination valve is retained between the filter media/core assembly and the end plate. The combination valve has a first portion that cooperates with the first inlet opening in the end plate and a second portion cooperating with the second inlet opening. In use fluid will pass through the first inlet opening, the filter media/core assembly and be discharged from the housing through the outlet opening.
