るロータリーコンプレツサ。 It has a cylinder that is closed on both sides by side blocks, and a rotor that has vanes inserted into the cylinder to form a compression chamber.A vane back pressure chamber is provided at the lower end of the vane, and one of the side blocks is closed. A pressure groove communicating with the vane back pressure chamber is formed in the end face, and the pressure groove and the high pressure chamber communicate with each other through a pressure supply passage, and a pressure difference between the discharge pressure and the suction pressure is formed in the middle of the pressure supply passage. A rotary compressor characterized by comprising a valve device that slides on and controls opening and closing of communication of a pressure supply passage.
