摘要：A scroll compressor employs therein a refrigerant having a small globalwarming potential and a small ozone depletion potential and mainly comprising
hydrofluoroolefin having a carbon-carbon double bond. A stationary scroll has and endplate and a discharge port defined in the end plate at a central portion thereof so as toopen into a discharge chamber. The stationary scroll also has a bypass hole defined in theend plate to allow a plurality of compression chambers to communicate with thedischarge chamber before the compression chambers communicate with the dischargeport. A check valve is provided on the bypass hole to allow the refrigerant to flow fromthe compression chambers to the discharge chamber. This construction can restrain abaneful influence on the global environment, reduce a temperature increase caused byexcessive compression, and restrain decomposition of the refrigerant even in long-termuse.
