Abstract
A fluid pressure responsive valve includes a valve member mounted on a guide pin slidably carried by a piston. A valve guide is engaged by one side of the valve element, and the piston engages the opposite side. The piston controls the valve member. The valve guide acts as a stop for a check valve element that controls communication through the inlet port, and also guides and supports the spring controlling the check valve element.
