Abstract
A drop compensated pressure regulator includes a spring casing, housing a regulator spring and a relief spring, a lower casing and a diaphragm sandwiched between the two casings. The lower casing has inlet and outlet ports. A one piece cam stem and relief seat is mounted for movement with the diaphragm and includes a cam surface that engages a movable disk holder. The disk holder is movable in a straight line within an orifice tube that supports a valve seat. A cylindrical lower spring seat is coupled by an O ring to the inner wall of the spring casing to dampen vibrations. The cam stem has built in stops to retain it within the orifice tube.
