Claims

[Claims for Utility Model Registration] 1. In the hollow part of the cylinder, a vane is provided with a wear-resistant coating such as tetrafluoroethylene resin on the outer peripheral surface of the rotor body, and is slidably fitted in the vane groove. A front side plate and a rear side plate are connected to the end face of the cylinder, and an inlet and an outlet are opened in the space surrounded by both side plates, the cylinder, and the rotor, so that the rotor can be accessed from the outside. In a vane compressor that rotates the rotor to compress the fluid sucked in from the suction port and discharges it from the discharge port, the back side mouth edge of the vane groove of the rotor is inserted from the outer periphery of the rotor into the vane groove. Depth towards end 20
~400μm, length from the rear wall of the vane groove to the rotor outer periphery in the opposite direction to the rotor rotation direction: 1.5 to 4mm
A vane compressor in which the notch extends across the entire width of the rotor and is provided so that the outer circumferential surface of the rotor body is not exposed from the wear-resistant coating. 2. The vane compressor according to claim 1, wherein the notch has a depth of 30 to 60 μm and a length of 2 to 3 mm. 3. The vane compressor according to claim 1, wherein the cylinder and rotor are made of Al material.
