ベーン型圧縮機。 It has a control member that is partially biased to the operating position side by the resultant force of the suction pressure and biasing force introduced into the low pressure chamber, and rotationally biased to the full operating position side by the control pressure formed in the high pressure chamber, and the control member In the vane type compressor, the capacity control mechanism is provided with a capacity control mechanism that controls the discharge capacity by changing the compression start timing by forward and reverse rotation of a control member in accordance with changes in the pressure chamber, and the capacity control mechanism includes a high pressure side The refrigerant is movable between a closed position where the passage and the low-pressure side passage communicating with the suction chamber are cut off, and an open position where the passages are communicated with each other, and is biased towards the closed position and has a discharge pressure. A check valve having an orifice for guiding gas to the high-pressure side passage, and a check valve that is held in the first position by a biasing force when running at a constant speed, and is moved to a second position against the biasing force when a high load occurs such as during sudden acceleration. and a piston that is displaced to the second position, and is configured such that when the piston is displaced to the second position, the piston displaces the check valve toward the open position and closes the orifice. A vane type compressor equipped with a capacity control mechanism.
