Abstract: A hermetic compressor having a frame, a cylinder provided at one side of the frame and having a compression chamber, a cylinder head coupled to the cylinder so as configured to hermetically seal the compression chamber and having a refrigerant discharge chamber to receive a refrigerant discharged from the compression chamber, a damping discharge chamber provided at the other side of the frame, a discharge guide path formed in the frame connecting the refrigerant discharge chamber and the damping discharge chamber, a discharge pipe having an entrance end connected to the damping discharge chamber, and an extension tube provided in the damping discharge chamber. The extension tube has an entrance end connected to an exit end of the discharge guide path, an exit end being spaced apart from an entrance end of the discharge pipe.

Abstract: A hermetic compressor having an improved refrigerant discharge path to efficiently reduce pulsation of a refrigerant to be discharged.

Abstract: A hermetic type compressor that includes a sealed casing, a suction pipe, a suction muffler, a compression unit, a driving unit, and a pressure adjusting unit. The suction pipe penetrates a side of the sealed casing. The suction muffler, the compression unit, and the driving unit are within the sealed casing. The suction muffler is coupled to the suction pipe, and the compression unit is coupled to suction muffler. The driving unit is coupled to the compression unit. The pressure adjusting device is on the suction muffler and configured to discharge liquid refrigerant into the sealed casing. The pressure adjusting device maintains the internal pressure of the suction muffler substantially constant.
