PCT No. PCT/JP93/01649 Sec. 371 Date Jul. 12, 1994 Sec. 102(e) Date Jul. 12, 1994 PCT Filed Nov. 11, 1993 PCT Pub. No. WO94/11635 PCT Pub. Date May 26, 1994.A housing has a refrigerant gas suction chamber at its center portion and a refrigerant gas discharge chamber at its peripheral portion. A valve plate between a cylinder block and a housing has a plurality of suction holes for connecting a plurality of cylinder bores in the cylinder block to the suction chamber and suction valves capable of opening the suction holes. The valve plate has a plurality of discharge holes for connecting the cylinder bores to the discharge chamber and discharge valves capable of opening the discharge holes. Pistons are reciprocatably accommodated in the cylinder bores. In accordance with reciprocation of the pistons, refrigerant gas is led into the cylinder bores from the suction chamber via the suction valves and suction holes. This refrigerant gas is compressed in the cylinder bores and is discharged to the discharge chamber via the discharge valves and discharge holes. A plurality of shielding members are provided in the discharge chamber in association with the plurality of discharge valves such that refrigerant gas discharged from any one of the plurality of discharge holes bypasses the discharge valves which are associated with the other discharge holes.
