ABSTRACT:
A valve assembly comprising a housing having a valve chamber, an inlet at one axial end of the valve chamber and an outlet at the opposite axial end of the valve chamber. A rib surrounds the inlet opening in the chamber. A valve element is mounted in the chamber comprising a generally disc-like body portion having a top face and a bottom face, and a plurality of pedestals depending from the bottom face. The top face of the valve element confronts the rib and the terminal ends of said legs abut the opposite axial end wall of the valve chamber. The axial height of the valve element is slightly greater than the axial depth of the valve chamber between the rib and opposite axial end wall so that a predetermined pressure at the inlet greater than pressure at the outlet is required to open the valve element. The peripheral wall of the valve chamber has at least one flow passage to permit flow from the inlet to the outlet when the valve element is lifted by a predetermined pressure at the inlet.
