HERMETIC COMPRESSOR |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To solve a problem that high pressure refrigerant gas leaks into a compression mechanism part through a gap of an abutment part of the compression mechanism part assembled by fastening of bolts and efficiency of the compressor drops when high pressure refrigerant such as carbon dioxide is used. <P>SOLUTION: The compression mechanism part 2 fastened by bolts or the like is fixed in a hermetic vessel 1 by welding or the like. A electric motor 3 driving the compression mechanism part and an oiling mechanism for feeding lubricating oil in the hermetic vessel to the compression mechanism part are provided and lubricating oil groove is provided on the abutment part 34 of the compression mechanism part fastened by bolts or the like. Consequently, a gap in the abutment part of the compression mechanism part assembled by bolt fastening is sealed by lubricating oil and efficient operation is enabled by preventing leak of high pressure refrigerant gas. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
