ス圧縮機の容量制御装置。 By fitting the unloader piston in a sealed and slidable manner in the unloader cylinder, one side of the unloader piston limits a chamber communicating with the gas compression chamber, and the other side limits a working chamber into which working gas is introduced. In a capacity control device for a gas compressor that controls the capacity by changing the top clearance volume by changing the pressure of the working gas and moving the unloader piston, the pressure in the chamber and the pressure in the working chamber are 1. A capacity control device for a gas compressor, comprising a control valve that performs feedback control of the differential pressure of the gas compressor as a linear function of the suction pressure of the gas compressor.
