Filter with combination valve having elongated openings in the end plate

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.
