HERMETIC COMPRESSOR
PROBLEM TO BE SOLVED: To provide a hermetic compressor capable of avoiding a reverse flow of oil when operation of a compressor is stopped. SOLUTION: A compression mechanism part 4 is located below a gas storage space 14 in a sealed container 3. An oil feed passage 11 feeds oil from an oil sump 32 to the sliding parts of the compression mechanism 4 in the gas storage space 14 and a compression space 24 and communicates the gas storage space 14 with a second space 26 behind a piston seen from an intake chamber 24. A second route 12 is a different route from the oil feed passage 11 and capable of flowing a gas medium from the gas storage space 14 to the second space 26. The passage resistance of the gas medium flowing through the second route 12 is lower than that of the gas medium flowing through the oil supply passage 11. COPYRIGHT: (C)2010,JPO&INPIT
