Abstract: 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.

Abstract translation: 涡旋式压缩机包括一个油回收泵，用于回收从壳体排出的油，从而有效地回收排出压缩机的油。 在抽吸完成时机之后，在与压缩室连通的位置处形成压差孔，使得储存在壳体的内部空间中的油能够利用压缩室的高压内部空间之间的压力差供应到压缩室 壳体和低压压缩室，从而即使在压缩机的低速驱动期间，也允许油顺利地供应到压缩单元，并且预先防止由于油引起的吸入损失的发生。
