摘要

The invention relates to an encapsulated motor-compressor unit for a refrigerator. The unit includes a capsule in which is resiliently mounted a combined or integrated motor and compressor having a common housing casting. The housing casting defines a cylinder for receiving a piston and a sound damping chamber. The housing casting has pressure and suction chambers at one end thereof and a suction passage which extends from the sound damping chamber to the suction chamber. The efficiency of the unit is improved by providing a tubular insert of thermally insulating material in the suction passage to reduce the transfer of heat from the compressor cylinder to the inlet gas in the suction passage.
