ABSTRACT:
A valve comprises a diaphragm and a diaphragm housing with a cover plate peripherally sealed against the diaphragm. The cover plate has a pressure port communicating therethrough for receiving a pressurized fluid. A reciprocable member contacts a side of the diaphragm opposite the cover plate and is reciprocable towards and away from the cover plate. A valve body carries the reciprocable member and has a valve seat and a discharge port therein. A valve closure member is carried by the diaphragm housing. Springs resiliently bias the valve body towards the diaphragm housing so the valve seat is normally in sealing engagement with the valve closure member. The valve closure member is movable away from the valve seat, to permit a fluid to pass between the closure member and the valve seat and out of the discharge port, when the pressure of a fluid from the pressure port against the diaphragm and the pressure of fluid on the closure member are sufficient to deflect the springs.
