圧制御装置。[Claim for Utility Model Registration] A rotor body is rotatably housed eccentrically or concentrically in a cylindrical cylinder chamber, and the vanes are fitted in one or more vane grooves drilled in the rotor body so as to be able to protrude. At the same time, the discharge gas pressure introduced from the discharge passage into the base of the vane groove is applied to the vane as a back pressure, and the rotation of the rotor body causes the tip of the vane to slide along the cylinder wall, so that the vane is partitioned by the vane. In a vane compressor that compresses the working gas in the working chamber by changing the volume of the working chamber, the compressor closes the discharge port when the discharge gas temperature is low, and closes the discharge port when the discharge gas temperature is high. A vane back pressure control device for a vane rotary compressor, characterized in that a valve body is installed to open the discharge port.
