ABSTRACT:
A check valve is disclosed made with a rotationally symetrical valve body with fluid inlet and outlet holes centered on the axis of symetry. A circular, flexible diaphragm is held in place inside the valve body by a mounting pin which extends through a hole in the diaphragm. The mounting pin and an opposing mounting pin receptical are supported by legs protruding inwardly from the inlet and outlet walls of the valve body and bridging over the inlet and outlet holes. The length of the legs determine the position of the diaphragm with respect to the inlet wall against which the diaphragm seals. Thus the opening pressure of the valve is dependant on the length of the legs.
