Claims

[Claims for Utility Model Registration] 1. A casing having a crank chamber, a cylinder head having a discharge chamber and a suction chamber and closing one open end of the casing, and a main shaft rotatably disposed within the casing. a swash plate that is provided in the crank chamber so as to be tiltable on the main shaft and rotates as the main shaft rotates; a rocking plate that is provided on an inclined surface of the swash plate and swings according to the rotation of the swash plate; A plurality of cylinders provided in the casing on the radially outer side of the main shaft, a piston arranged reciprocatingly in the cylinder and connected to the rocking plate, and the crank chamber and the suction chamber communicate with each other. a communication passage; and a pressure-sensitive control valve that is provided in the communication passage and controls communication between the crank chamber and the suction chamber via the communication passage according to pressures in the crank chamber and the suction chamber. The variable capacity swash plate compressor is characterized in that the communication path is provided with an external control valve in series with the pressure-sensitive control valve, and the external control valve has an opening degree that changes by adjusting the current. Variable capacity swash plate compressor. 2. The variable capacity tilt type according to claim 1, wherein the external control valve has a structure that automatically opens the valve when the differential pressure between the crank chamber pressure and the suction chamber pressure exceeds a predetermined value. Plate compressor.
