Abstract
In a reciprocating compressor in which a suction valve ( ) of a leaf valve is placed between a valve plate ( ) and a cylinder block ( ) to open and close a suction port ( ) formed in the valve plate, the suction valve is previously bent to open the suction port in an initial state when the compressor is stopped. The cylinder block has a cylinder bore ( ) with which the suction port is communicated and into which a piston ( ) is inserted. When the piston performs reciprocating movement in the cylinder bore, the suction valve opens and closes the suction port in response to the reciprocating movement in a pulsation reducing manner.
