<P>PROBLEM TO BE SOLVED: To prevent a sliding part of a compression mechanism part from being abnormally worn and a refrigerant oil to be discharged from a hermetic compressor apparatus from being rapidly increased by supplying the refrigerant oil accumulated in an upper space of a stator into the compression mechanism part. <P>SOLUTION: A bypass pipe 10 connecting an upper space and a lower space of the stator 9 is provided in a hermetic container 1. The refrigerant oil flows into the lower space of the stator 9 via the bypass pipe 10, and is supplied to the compression mechanism part. Moreover, the refrigerant oil is prevented from being retained in the upper space of the stator 9, and the refrigerant oil to be discharged from the hermetic compressor can be prevented from being rapidly increased. <P>COPYRIGHT: (C)2012,JPO&INPIT |
