ABSTRACT:
A hermetic motor-compressor for a refrigerating system. The hermetic motor-compressor has a motor component and a compressor component drivingly coupled to each other and disposed within a closed container. The refrigerant gas introduced from an evaporator of a refrigerating system through a return pipe is once released into the space within the closed container and then sucked by the compressor component so as to be compressed and discharged to the outside. A barrier is provided on the outer periphery of the motor and compressor components for preventing a main flow of the refrigerant gas introduced into the closed container through the return pipe from flowing into the circumference of high-temperature portions of the hermetic motor-compressor.
