徴とするベーンコンプレッサの容量調整装置。It consists of a rotor that slidably supports the vanes, a cylindrical liner that surrounds the rotor, and a side plate that covers the side of the liner, and a boat that communicates the suction pressure chamber and the working space with the side plate and this port. In the vane compressor capacity adjustment device, the vane compressor capacity adjustment device includes a rotary valve member that adjusts the opening degree of the vane compressor, and a housing provided adjacent to the side plate includes an intermediate pressure chamber communicating with the bearing chamber of the rotor, and one end of which is connected to the intermediate pressure chamber. A cylinder is provided that communicates with the chamber and the other end communicates with the suction pressure chamber, and a rack piston that meshes with a gear portion provided on the rotating shaft of the front gloss rotary valve member is fitted into the cylinder for reciprocating movement, A spring for pressing the rack piston is provided at an end communicating with the suction pressure chamber, and a passage is provided to communicate the intermediate royal chamber and the suction pressure chamber, and opening and closing of this passage is controlled by a solenoid valve. Vane compressor capacity adjustment device.
