Abstract
There is provided a vane compressor with a plurality of vanes having a structure in which a rotor portion and a rotary shaft are unitarily formed so as to reduce bearing sliding loss of the rotary shaft and reduce gas leakage loss by narrowing a space formed between the rotor portion and the inner peripheral surface of a cylinder. In the vane compressor with the plurality of vanes according to the present invention, an angle α of a circular arc constituting the partial ring shape of each vane aligner satisfies a relationship of where R is a distance between the rotational central axis of each bush and the rotational central axis of the rotor portion, e is a distance between the central axis of the inner peripheral surface of the cylinder and the rotational central axis of the rotor portion, and N (a natural number of two or greater) is the number of the vanes.
