ABSTRACT:
A valve mechanism of a refrigerant compressor is disclosed. The compressor invention includes a valve plate which is disposed between a compression chamber and a suction chamber of the and has an inlet port formed there-through for fluid communication between the suction and compression chambers, and a flap type suction valve which is located on the side of the valve plate adjacent the compression chamber and has a proximal portion secured to the valve plate and a flexible distal portion movable between closed position thereof where the fluid communication is shut off and open position where the fluid communication is established. The valve plate is provided with a rib-formed support for supporting the suction valve when it is closed against the inlet port opening. The supporting rib extends approximately to the center of the inlet opening on the side of the inlet port adjacent the suction valve to provide a point of support at the center of the inlet opening. The inlet port is extended in cross sectional area so as to admit an increased volume of refrigerant gas into the compression chamber.
