ABSTRACT:
A relief valve assembly includes a valve element mounted for movement along a valve axis between a sealing position and a relief position. A spring arm engaged with the valve element urges the valve element toward the sealing position. The spring arm has a free end engaged upon a cam surface. Movement of the valve element between the sealing and relief positions causes movement of the free end of the spring arm along the cam surface. Movement of the valve element toward the relief position causes movement of the free end of the spring arm along the cam surface increasing spacing of the free end of the spring arm from the valve axis and increasing spring force of the free end of the spring arm upon the cam surface. This maintains a substantially constant, predetermined spring force component urging the valve element toward the sealed position.
