ABSTRACT:
A spring diaphragm for use in automatic hydraulic control valves of the type having a valve body having an inlet chamber, and an outlet chamber and a spring diaphragm interposed between the inlet and outlet chambers, which spring diaphragm, as a result of hydraulic pressure, is automatically moveable between an open and closed position, in which the diaphragm allows and prevents, respectively, communication between the inlet and outlet chambers, includes a two-part diaphragm element including a first lower part and second upper part generally spaced apart from one another, the first lower part being in the form of a flexible elastic disc which performs the function of a hermetic seal between the inlet and outlet chambers when the spring diaphragm is in the closed position and the second upper part being connected to the first part and being in the form of a resilient disc which performs the function of a spring to normally bias the spring diaphragm from the open to the closed position. The first and second parts each have resilient spring-like ribs on the first lower part serving to aid hermetic sealing when the diaphragm is in the closed position and the ribs on the second upper part serve to provide a main force to bias the diaphragm into the closed position.
