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. 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.
