Abstract: AN ELECTRICALLY-OPERATED SEALED COMPRESSOR INCLUDES A CYLINDER (507), A CYLINDER HEAD MOUNTED ON THE CYLINDER (507) AND HAVING A SUCTION CHAMBER AND FIRST AND SECOND DISCHARGE CHAMBERS, A PISTON (512) ACCOMMODATED IN THE CYLINDER (507), AND A VALVE MECHANISM. THE VALVE MECHANISM INCLUDES A SUCTION MUFFLER (517) AND A VALVE PLATE (513) HAVING AT LEAST ONE SUCTION PORT, FIRST AND SECOND DISCHARGE PORTS, AND FIRST AND SECOND PASS HOLES. THE FIRST DISCHARGE PORT AND THE FIRST PASS HOLE COMMUNICATE WITH THE FIRST DISCHARGE CHAMBER, WHILE THE SECOND DISCHARGE PORT AND THE SECOND PASS HOLE COMMUNICATE WITH THE SECOND DISCHARGE CHAMBER. THE VALVE MECHANISM ALSO INCLUDES FIRST AND SECOND DISCHARGE VALVES MOUNTED ON THE VALVE PLATE (513) AND ACCOMMODATED IN THE FIRST AND SECOND DISCHARGE CHAMBERS, RESPECTIVELY, A SUCTION REED HAVING A REED VALVE FOR SELECTIVELY OPENING AND CLOSING THE SUCTION PORT, A DISCHARGE GASKET FOR SEALING THE VALVE PLATE (513) AND THE CYLINDER HEAD, AND A DISCHARGE MUFFLER. THE FIRST AND SECOND DISCHARGE CHAMBERS ARE SEPARATED FROM EACH OTHER BY THE DISCHARGE GASKET TO FORM RESPECTIVE INDEPENDENT SPACES, WHILE THE FIRST AND SECOND PASS HOLES COMMUNICATE WITH THE DISCHARGE MUFFLER.(FIG. 1)

Abstract: An electrically-operated sealed compressor includes a cylinder, a cylinder head mounted on the cylinder and having a suction chamber and first and second discharge chambers, a piston accommodated in the cylinder, and a valve mechanism. The valve mechanism includes a suction muffler and a valve plate having at least one suction port, first and second discharge ports, and first and second pass holes. The first discharge port and the first pass hole communicate with the first discharge chamber, while the second discharge port and the second pass hole communicate with the second discharge chamber. The valve mechanism also includes first and second discharge valves mounted on the valve plate and accommodated in the first and second discharge chambers, respectively, a suction reed having a reed valve for selectively opening and closing the suction port, a discharge gasket for sealing the valve plate and the cylinder head, and a discharge muffler. The first and second discharge chambers are separated from each other by the discharge gasket to form respective independent spaces, while the first and second pass holes communicate with the discharge muffler.

Abstract: In a hermetic compressor in a freezing refrigerating system or an air-conditioning system such as a refrigerator or a showcase, a construction is disclosed for intending to provide a low-noise hermetic compressor by effectively attenuating a pressure pulsation having occurred in a compression chamber with a suction muffler. By this construction, since a muffler cover 20 has a planar simple shape, the deformation upon molding becomes little and it can come into fully close contact with a muffler main body 19. Therefore, the pressure pulsation hardly leaks through the connecting portion between the muffler main body 19 and the muffler cover 20. The full silencing effect that the suction muffler 18 has is obtained and thereby noise can be reduced more effectively.
