Abstract: A filter assembly having a housing open at one end, and an annular filter element disposed in the housing. An end plate having elongated openings and auxiliary openings are arranged in a generally circular configuration radially equidistant from the center of the end plate. 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 annular filter element and the end plate. The combination valve includes an annular shoulder subdividing the elongated openings into inlet opening portions and bypass opening portions. The combination valve has a first portion that cooperates with the inlet opening portions in the end plate and a second portion that cooperates with the bypass opening portions. The second portion has more resistance to fluid flow than the first portion.

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 one inlet opening and an outlet opening closes the open end of the housing. A spring having at least one bypass opening is disposed between the end of the filter media/core assembly to bias the annular filter media/core assembly towards the end plate. The end plate is affixed to a lid which is secured to the end of the housing. A first valve or anti-drainback valve cooperating with the inlet opening is retained between the filter media/core assembly and the end plate. A second valve or bypass valve cooperating with the bypass opening is retained between the filter media/core assembly and the spring. In operation, fluid will pass through the inlet opening, the filter media/core assembly and be discharged from the housing through the outlet opening.

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.
