Abstract (en)

A vane compressor which is capable of preventing degradation of the sliding characteristics of its rotor (2) due to tolerances of the rotor (2) and parts associated therewith, and at the same time reducing the manufacturing costs and weights of the compressor. The vane compressor includes a cam ring (1), a rotor (2) rotatably received in the cam ring (1), a plurality of vane slits (13) formed in the rotor (2), vanes (14) slidably received in respective ones of the vane slits (13), and side members (3, 6) secured to respective end faces of the cam ring (1), at least the rotor (2) and the side members (3, 6) being formed of an aluminium-based material. A spacer (70) of annular shape is arranged between at least one of the end faces of the rotor (2) and a rotor-side end face of a corresponding one of the side members (3, 6). The spacer (70) is formed of a material which is harder than the aluminium-based material and smaller in outer diameter than an outer diameter of the rotor (2). <IMAGE>
