ABSTRACT:
A hermetic compressor system includes a compressor and an electric drive resiliently supported in a closed housing. A metallic cylinder head is secured to the compressor and defines an insertion hole. The cylinder head has a suction chamber, which communicates with the insertion hole, and a discharge chamber integrally formed with and adjacent to the suction chamber. A suction muffler made of a synthetic resin or equivalent material of low thermal conductivity has a communicating duct extending through the insertion hole and partially disposed within the suction chamber. An opening is formed in the end of the communicating duct disposed within the suction chamber in a position facing a suction port leading a refrigerant gas into the compressor.
