Abstract: A hermetic compressor includes a sealed casing which accommodates therein a compressing unit for compressing a refrigerant and a driving unit for driving the compressing unit. A communication passage is provided for establishing communication between the compressing unit and a discharge muffler. The discharge muffler is formed therein with a substantially annular hermetic passage for the compressed refrigerant introduced via the communication passage. In the substantially annular hermetic passage, the introduced compressed refrigerant is bifurcated in opposite directions. The substantially annular hermetic passage has an outlet in the discharge muffler. At the outlet, the bifurcated refrigerant joins and flows out of the substantially annular hermetic passage so as to reduce pressure pulsation of the compressed refrigerant by canceling pressure pulsation components contained in the bifurcated refrigerant.

Abstract: A compressor equipped with a compressing unit comprising a compressing section and a motor section which are connected to each other and Which are encased in a closed vessel, the compressing section including a crank shaft rotatable so that a piston reciprocates within a cylinder and the motor section comprising a rotor and stator and disposed at a lower side of the compressing section, the rotor being connected to the crank shaft so that the crank shaft is rotatable in response to driving of the motor section. Springs are provided between the compressing unit and the closed vessel so as to elastically support the compressing section and the motor section, and first and second balance weights are respectively provided on upper and lower portions of a rotor of the motor section.

Abstract: A hermetic compressor includes a sealed casing which accommodates therein a compressing unit for compressing a refrigerant and a driving unit for driving the compressing unit. An induction pipe 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 corresponding to a node of a standing wave of the refrigerant in the sealed casing.
