PROBLEM TO BE SOLVED: To prevent lowering of function as an expansion type silencing mechanism by preventing bending of discharge gas in an exhaust gas outflow path, and to reduce pulsating noise of low frequency by providing the discharge gas outflow path with a sufficient length in the expansion type silencing mechanism used for a high-pressure dome type compressor. SOLUTION: The compressor is equipped with the silencing mechanism 47 having a discharge cover 43 which forms an expansion space 42 of the discharge gas by covering a discharge port 29 provided in a compression mechanism 20 and is formed with a discharge gas outlet 46 from the expansion space 42 into a casing 10. The expansion space 42 is formed along a spiral path of one turn or more passing the discharge port 29 and the discharge gas outlet 46. COPYRIGHT: (C)2007,JPO&INPIT
