  • Patent number: 8585373
    Abstract: The present invention discloses a hermetic compressor which can reduce the noise by regulating a suction pressure in a connector enabling a suction pipe of a hermetic container and a suction muffler to communicate with each other. The hermetic compressor includes: a hermetic container including a suction pipe through which refrigerant is sucked and accommodating a compression mechanism unit for compressing the refrigerant; a suction muffler fixed to the compression mechanism unit and reducing the flow noise when the refrigerant passes; and a connector enabling the suction pipe and the suction muffler to communicate with each other and including a hole on a refrigerant passage to communicate with an inner space of the hermetic container. An inner pressure of the connector is equalized with an inner pressure of the hermetic container, which raises a refrigerant suction pressure.

  • Patent number: 8230968
    Abstract: The present invention discloses a suction muffler for a hermetic compressor which reduces noise of refrigerant. A plate film operating as a kind of flow resistance is provided on a refrigerant suction passage in various shapes and specific positions. Therefore, the suction muffler can effectively reduce pressure pulsation transferred to the outside and guarantee flow efficiency, although the refrigerant is directly sucked thereinto.

  • Publication number: 20090028726
    Abstract: Disclosed is a suction muffler for a hermetic compressor. The suction muffler includes first and second bodies coupled to each other. The first and second bodies have coupling protrusion and recess formed in corresponding positions, respectively. A coupling rib protrudes from the coupling protrusion, and a coupling channel is formed as an indentation on the coupling recess. Coupling guide surfaces are formed on corresponding portions of the coupling rib and recess, respectively, so that the coupling protrusion and recess can be fastened to each other more smoothly. The coupling guide surfaces of the coupling protrusion and recess guide and facilitate the coupling between the first and second bodies. The coupling protrusion and recess are coupled to each other by geometric characteristics so that no separate process is necessary to couple the first and second bodies to each other. This improves the productivity and quality of the suction muffler.
