ABSTRACT:
A control valve for use in an automotive fuel pump. A housing is installed in the fuel pump and has a central circular opening therethrough the peripheral surface of which is curved. A valve member is movable relative to the circular opening and has an outer curved contact surface for sealingly contacting the curved peripheral surface to prevent flow of a fuel through the opening. The curved surface of the valve member tangentially contacts the curved peripheral surface to seal against flow. A coil compression spring seats against one end of the housing and continuously urges the valve member into sealing contact with the curved peripheral surface. The force exerted by the spring on the valve member is such that it remains seated and a minimal amount of fuel leakage occurs through the control valve when the fuel pump is not pumping even though the curved contact surface of the valve member is subjected to a force applied in the normal direction of fuel flow through the control valve equal to a predetermined positive head of fuel.
