プレッサ。A two-stage compression type rotary compressor is provided with both compression mechanism sections of a rotary set on a high pressure side and a low pressure side, and the two compression mechanism sections are respectively rotationally driven as a rotary shaft rotationally driven by an electric motor. When a bypass pipe for liquid injection is connected to the compression mechanism section on the side, the discharge volume of the compression mechanism section on the high pressure side is set to 0.0% of the discharge volume of the compression mechanism section on the low pressure side. 6-0.
65. A two-stage compression type rotary compressor.
