Patent ID: 7578660

Claim:
A hermetic compressor comprising: a sealed housing connected to a suction pipe that leads a suction gas into the sealed housing and a discharge pipe that leads a discharge gas out of the sealed housing; a compression mechanism disposed in the sealed housing, and including a compression chamber, a suction passage connected to the suction pipe and open to the compression chamber, and a discharge passage fluidly connected to an inner space of the sealed housing, and open to the compression chamber; an electric motor disposed in the sealed housing to rotate about a rotation axis, the electric motor being operatively coupled to the compression mechanism; a differential pressure force canceling mechanism configured to allow a pressure of the suction gas to act on the compression mechanism to reduce a pressing force from the discharge gas in the sealed housing that acts on the compression mechanism along an axis of the suction passage, the differential pressure force cancelling mechanism forming a space with pressure of the suction gas between the sealed housing and the compression mechanism; and a resilient member supporting the compression mechanism and the electric motor relative to the sealed housing along the rotation axis, an open end of the suction pipe having an end face that faces an external surface of the compression mechanism having an opening of the suction passage formed therein, with a sliding connection fluidly connecting the open end of the suction pipe and the opening of the suction passage such that an area between the open end of the suction pipe and the opening of the suction passage is sealed and such that the opening of the suction passageway is movable along the rotation axis relative to the open end of the suction pipe.
