Abstract (en)
Provided is a scroll compressor capable of inhibiting occurrence of pulsation of a fluid. The scroll compressor includes: an on/off valve (38) that opens when the capacity control operation of a fluid is turned on, and returns a mid-compression fluid, which is discharged to an intermediate chamber (81), to a suction chamber (17); and a second check valve (42) that opens when the capacity control operation is turned off and when a pressure in the intermediate chamber (81) becomes higher than a pressure in a discharge chamber (16), and discharges the mid-compression fluid, which is discharged to the intermediate chamber (81), to the discharge chamber (16) via a discharge port (85).
