ン型圧縮機。 The vane is compressed by the pressure in the back pressure chamber defined between the base end of the vane fitted in the vane groove of the rotor and the bottom of the vane groove, which is disposed in a cam ring whose both sides are closed with side blocks. Back pressure is applied, and this back pressure and centrifugal force press the tip end surface of the vane against the inner circumferential surface of the cam ring, and as the rotor rotates, the cam ring, side block, rotor, and vane form a The compressing action is performed by the volume fluctuation of the compression chamber, and the side blocks include a back pressure communication groove that communicates with the back pressure chamber, and a back that is continuous with the back pressure communication groove and is a grooveless portion. In the vane compressor, the vane tip pressure can be adjusted by providing a confining portion for sealing the pressure chamber, and the back pressure communication groove has a shape that reduces the load on the back of the vane at least in the suction stroke range. A vane type compressor characterized by:
