ABSTRACT:
A multi-cylinder piston-operated compressor having a cylinder consisting of an axially combined cylinder block closed at both axial ends by front and rear housings having suction and discharge chambers therein, a reciprocative piston mechanism arranged in the cylinder for sucking, compressing, and discharging a refrigerant gas, and a connecting flange from which the refrigerant gas after compression is sent toward an air-conditioning circuit. The cylinder block and the connecting flange define a muffling chamber for deadening pulsation in the pressure of the discharged refrigerant gas. The compressor further has front and rear delivery passageways axially extending from the front and rear discharge chambers and having different axial lengths, to cause a pressure differential between the flow of the discharged refrigerant gas passing through the front delivery passageway and that of the discharged refrigerant gas passing through the rear delivery passageway, thereby producing an agitated flow of the compressed refrigerant gas within the muffling chamber.
