えるようになしたことを特徴とする気体圧縮機。A compressor body comprising a rotor having a plurality of vanes that can move forward and backward in the radial direction is rotatably suspended in a cylinder chamber configured by a cylinder and both side blocks attached to both sides of the cylinder; A sealed system that houses the compressor main body, forms a space at the rear of the rear side block, stores lubricating oil under discharge pressure in this space, and holds the tip of the rotor shaft of the front rotor rotatably. A casing is provided, and the lubricating oil is supplied to each part by discharge pressure, and at the same time, a part of the lubricating oil is forced into the slit of the rotor in which the vane is held, and the oil pressure is applied to the inner wall of the cylinder chamber. In the device for obtaining the contact pressure of the vanes, a first groove concentric with the outer circumferential end surface of the bearing portion of the rotor shaft is formed on the contact surface between each of the side blocks and the rotor; Medium-pressure lubricating oil seeped from the bearing part is added to the bottom of the slit through the groove, and the groove is concentric with the first groove and communicates with a high-pressure lubricating oil passage, and the vane has a maximum protrusion. A second groove is formed on the end face of each side block, and a communication groove communicating with the bottom of the vane is formed near the discharge port of the second groove. A gas compressor characterized in that, by doing so, high-pressure hydraulic pressure is applied to the bottom of the vane through the second groove in the vicinity of the discharge port.
