Claims

[Claims for Utility Model Registration] 1. In a space enclosed by a cylindrical or elliptical cylinder and small front and rear side plates joined to the end faces of the cylinder, a utility model rotatably supported by the side plates. A rotor is fixed to a drive shaft, and a vane groove is formed on the outer circumferential surface of the rotor over its entire width, and a vane that slides in contact with the inner circumferential surface of the cylinder and the front and rear side plates is recessed in the vane groove. In the vane compressor, a pressure groove communicating with the vane groove is provided on the front surface of the rear side plate, and a rear end of the drive shaft is provided on the rear surface of the rear side plate. A cover is provided to cover the rear bearing chamber to form a sealed rear bearing chamber, and the pressure groove is communicated with the pressure groove, and the compression chamber formed by the cylinder, front and rear side plates, vanes, etc. is connected to the rear bearing chamber. A compressor characterized in that a chamber is communicated with a chamber through a pressure conducting hole provided in a rear side plate. 2. The vane compressor according to claim 1, wherein the pressure groove communicating with the vane groove is provided from the compression chamber near the start of the suction stroke to the vane of the compression chamber near the start of the compression stroke. 3. The vane compressor according to claim 1, which has a communication hole for guiding part of the gas from the pressure guiding hole to the pressure groove without passing through the gap in the rear side plate burr bearing. 4. The vane compressor according to claim 1, wherein the pressure guiding hole is opened in the compression chamber at the end of the suction stroke or near the start of the compression stroke.
