Hermetic type compressor having an oil feed part |
摘要 |
In a hermetic type compressor, a sliding part (11) between a main shaft (4) and a lower end plate (8) is large in wear, and it is not allowed to operate stably for a long period. By communicating between the sliding part (11) and an oil feed pump (9) through an oil feed port (12), refrigerating machine oil (2) is supplied by force into the sliding part (11), and hence the lubrication is improved and the reliability is enhanced. In particular, it is preferably applied to the hermetic type compressor using HFC derivative refrigerants.
