ABSTRACT A reciprocating piston hermetic compressor disclosed, including a crankcase defining a cylinder, and a cylinder head and valve plate assembly attached to the top surface of the crankcase to cover the cylinder. A cantilevered suction leaf valve has an attached end intermediate the crankcase top surface and the valve plate. During a compression stroke of the compressor, the unattached end of the suction valve is forced by pressure against the valve plate to cover a suction inlet opening. During an intake stroke of the compressor, the unattached end is drawn away from the valve plate to open the suction inlet opening. The unattached end of the suction valve is limited in its travel into the cylinder by engagement with a positive stop defined by a generally inclined milled surface intersecting the crankcase top surface and the cylinder wall.
