摘要:
The invention concerns a scroll compressor which is low in noise caused by water hammering of a refrigerant gas just after a discharge valve is closed. The scroll compressor includes a discharge member (45) having a discharge port (8) opposed to a discharge port (5) of a fixed scroll (2) and a discharge valve (9) opposed to the discharge port (8) of the discharge member (45) and opened/closed depending on a difference between flow passage pressure of a refrigerant gas and pressure in a high pressure space (27) in a sealed vessel (1). At least either of the fixed scroll (2) and the discharge member (45) is formed with a counterboring part which communicates with an intermediate pressure chamber after the high and intermediate pressure chambers have begun to communicate via separation of the spiral teeth.
