Reciprocating-piston-type compressor having piston entering discharge chamber
 A reciprocating piston type compressor for compressing refrigerant gas includes a cylinder block with a plurality of parallel cylinder bores arranged around the longitudinal axis of the cylinder block, the cylinder bores having bore ends as discharge ports of the same diameter as that of the cylinder bores, a plurality of pistons slidably provided within the cylinder bores for reciprocating between the top and bottom dead centers, the inner surface of the cylinder bores and the end faces of the piston defining compression chambers, housing means sealingly mounted to the either ends of the cylinder block, the housing means including at least a discharge chamber into which the compressed refrigerant gas is discharged from the compression chambers through the bore ends, a drive shaft for driving compressing motion of the reciprocating pistons within the cylinder bores, the drive shaft extending along the longitudinal axis of the compressor, and valve members for closing the bore ends of the cylinder bores, the valve members being movable in the axial direction between a closed position where the valve members close the bore ends, and an open position where the valve members are away from the bore ends.
