PROBLEM TO BE SOLVED: To solve problem of a conventional compressor installed in a hermetic container maintained in high temperature and high pressure atmosphere in which, though a part of the lubricating oil fed to the compressor can be fed to the expander by disposing the expander under the compressor, i.e., in or near a lubricating oil pool accumulated under the hermetic container when an expander is connected to the compressor, heat is moved between the compressor 102 and the expander 103 by the circulation of the lubricating oil so that the temperatures thereof can be uniformized and a cycle efficiency is lowered.;SOLUTION: A cooling water passage 220 is installed near the lubricating oil communication passage 212 of an intermediate plate 211 which partitions a space 202 on the compressor 102 side from a space on the expander 103 side to cool the lubricating oil.;COPYRIGHT: (C)2007,JPO&INPIT
