Claims

[Scope of utility model registration request]

A rotor having a plurality of vanes that can move forward and backward is rotatably disposed in a cylinder chamber composed of a cylinder having an elliptical inner circumference and front and rear side plates joined to both sides of the cylinder, and A chamber is formed at the rear of the rear side plate, lubricating oil under discharge pressure is stored in the chamber, and the lubricating oil is forced by the discharge pressure into a vane back pressure chamber formed near the rotor axis. In a vane compressor in which the tip of the vane is brought into pressure contact with the inner wall of the cylinder chamber by this hydraulic pressure, the retraction of the vane is applied to the surface of the side plate that makes sliding contact with the rotor from the time when the vane starts to protrude (at the beginning of the suction stroke). Towards the end of the compression stroke (the end of the compression stroke), an arc-shaped oil groove is provided that communicates with the vane back pressure chamber and is concentric with the rotor, and from the initial stage of the vane protrusion in the groove to the point at which the vane protrusion speed reaches its maximum. Small holes are formed at appropriate positions in the range from the time when the retraction speed of the vane reaches its maximum to the end of the compression stroke, and the ends of the small holes are connected to the chamber chamber formed in the rear side plate. A vane compressor characterized in that the vane compressor is connected to an oil passage that communicates with the oil passage.゛
