Abstract

A scroll compressor is provided that includes an oil recollecting pump to recollect oil discharged from a shell, thus to effectively recollect oil discharged out of the compressor, and a differential pressure hole 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 a pressure difference between a high-pressure inner space of the shell and a 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 an occurrence of a suction loss due to oil.
