A cylindrical valve element is spring biased to a position to prevent communication between the inlet or outlet and the discharge passage. The valve element includes areas at opposite ends with one area being larger than the other so that pressure in the inlet and outlet act on the valve in a direction opposite the spring bias so as to open the inlet and outlet to the discharge passage upon a predetermined increase in pressure.
