摘要： 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. As a difference between the refrigerant suction pressure and the pressure of the compression space is reduced, the noise generated during the refrigerant suction can be reduced.

摘要： 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.
