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: A compressor includes a sealed casing (2) which accommodates therein a compressing unit (6) for compressing a refrigerant and a driving unit (7) for driving the compressing unit. An induction pipe (18) is provided in the sealed casing for introducing the refrigerant into the compressing unit. The induction pipe has an outlet end communicating with the interior of the compressing unit and an inlet end which is opened to space in the sealed casing at a position which may correspond to a node of a standing wave of the refrigerant in the sealed casing.

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.

Abstract: Una compresora cerrada silenciosa para dispositivos de congelamiento y refrigeracion tales como refrigeradores y escaparates y acondicionadores de aire capaces de atenuar de manera efectiva una pulsacion de presion producida en una camara de compresion por un mofle de entrada, en donde una cubierta de mofle (20) esta formada en una configuracion de placa simple para reducir la deformacion de la misma en el momento de formacion y para ajustarse lo suficiente de manera mas cercana al cuerpo del mofle (19), por lo que la pulsacion de presion dificilmente causa fugas de una parte de la conexion entre el cuerpo del mofle (19) y la cubierta de mofle (20), y un efecto silenciador de ruido del mofle de succion (18) se puede desarrollar lo suficiente para reducir de manera mas efectiva el ruido.
