<p>There is provided a vane compressor including a plurality of vanes that performs a compression operation such that the normal to a circular arc formed by each vane tip portion and the normal to the inner peripheral surface of a cylinder are constantly approximately coincident with each other. In the vane compressor according to the present invention, each of the plurality of vanes is held to be constantly in the normal direction of the inner peripheral surface of the cylinder or is held to be constantly along a direction having a fixed inclination with respect to the normal direction of the inner peripheral surface of the cylinder so that the compression operation is performed in the state where the normal to the circular arc formed by the tip portion of each of the plurality of vanes and the normal to the inner peripheral surface of the cylinder are constantly approximately coincident with each other. Further, the plurality of vanes are rotatably and movably supported with respect to the rotor portion in the rotor portion. A concave portion or a ring-shaped groove being concentric with the inner diameter of the cylinder is formed in an end surface of each of the cylinder head and the frame on the side of the cylinder, a pair of vane aligners are fitted in the concave portion or the ring-shaped groove, and a plate-like projection or a groove of each of the vane aligners is fitted in a groove or a projection provided at each of the plurality of vanes. Each of the vane aligners includes the plate-like projection or the groove at a partial-ring-shaped end surface thereof.</p> |
