SCROLL COMPRESSOR

摘要

A scroll compressor includes an oil recollecting pump for recollecting oil discharged from a shell, thus to effectively recollect oil discharged out of the compressor. A differential pressure hole is formed at a position where it communicates with compression chambers after a suction completion timing such that oil stored in an inner space of the shell can be supplied into the compression chambers using pressure difference between the high-pressure inner space of the shell and the low-pressure compression chambers, resulting in allowing oil to be smoothly supplied to a compression unit even during low-speed driving of the compressor and preventing beforehand an occurrence of a suction loss due to oil.
