A scroll compressor is provided. A communication hole for communicating a discharge space and a thrust bearing surface with each other is formed at a fixed scroll. This can reduce frictional loss occurring between the fixed scroll and an orbiting scroll. Further, if a high vacuum is about to occur while the compressor is operated, a refrigerant in the discharge space is introduced into the compression chambers through the communication hole. This can prevent the occurrence of a high vacuum to thereby prevent damage of the compressor. Besides, when the compressor is stopped, a pressure equilibrium is performed through the communication hole. |
