Abstract
A piston cylinder and head arrangement for compressors including a valve plate disposed between a piston housing and the head. An intake valve, a discharge valve, and an atmospheric vent valve are all operably disposed in the valve plate, and are all arranged relative to each other and relative to an intake chamber, a compression chamber, and cooling chambers so as to necessitate only one sealing gasket for sealing said valves and said chambers from each other during certain operational phases of the compressor. The arrangement further includes a piston operable responsively to discharge pressure in excess of a certain high degree for diverting such pressure output from the pressure discharge valve to the atmospheric vent valve until such pressure drops below the certain high degree.
