Claims

[Scope of utility model registration request]

(1) A cylinder that is formed into a substantially elliptical or eccentric cylindrical shape and has an intake port and a discharge port formed inside and outside, and an intake or discharge side that is attached to both sides of the cylinder and communicates with each of the above ports. A rotor having a plurality of bays that can move forward and backward in the radial direction is rotatably suspended horizontally in a cylinder chamber formed by front and rear side blocks formed with circulation holes, the cylinder and both side blocks, and the above-mentioned A valve element that is biased in a direction away from the port surface is placed on the intake port of the cylinder, and the intake port is opened and closed by contacting and separating the valve element from the port surface depending on the negative pressure in the cylinder chamber. In such a gas compressor, an actuator that protrudes into the cylinder chamber when the intake port of the valve body is closed is integrally provided at the tip of the valve body, and when the actuator collides with the tip of the rotating vane, the valve body closes. A gas compressor forcibly separating the body from the port surface.

(2) The intake port is configured separately from an intake port provided with the valve body, and a sub-intake port that communicates with the intake side vent together with the main intake port and is formed on the lag side in the rotor rotational direction. A gas compressor according to claim 1, which is a utility model.
