とを特徴とする可変容量型圧縮機。 It is equipped with a suction chamber, a discharge chamber, a crank chamber, and a swash plate that swings in the crank chamber as the drive shaft rotates. In a variable capacity compressor in which the discharge amount is controlled by changing the inclination angle of the swash plate according to the crank chamber pressure, a discharge chamber is provided in a communication passage communicating between the discharge chamber and the crank chamber. A variable capacity compressor, comprising: a control valve that opens to open the communication passage when a rate of increase in the discharge pressure of the compressor exceeds a predetermined value.
