There is provided a vane compressor which prevents leakage of refrigerant gas by decreasing the number of airtight interfaces between component parts and prevents seizure from occurring between its rotor and its side block without surface treatment of the side block. The vane compressor has a cam ring. The rotor is rotatably received in the cam ring. A first head is secured to one end face of the cam ring. A second head is secured to another end face of the cam ring in a manner such that the second head closes an opening of the another end face of the cam ring and one end face of the rotor can be brought into contact with the second head. The side block is received in the first head in a manner such that it closes an opening of the one end face of the cam ring and another end face of the rotor can be brought into contact with the side block.

Vane compressor

In a suction port for a vane-type compressor in which suction holes 15a and 15 a along the inner peripheral edge 1a of the cylinder 1 are disposed in the read side block 4 and notch portions 15b and 15b opposing to the suction holes 15a are disposed at the opening edge on he suction side of cylinder 1, the suction holes 15a and 15a are arranged outside the vane sliding zone of the rotor-side end face 4a of the rear side block 4. If a vane juts out of a vane groove, the tip of vane does not enter the suction holes 15a and 15a even if the tip of a vane is inclined, so that the vane does not heavily rub the end portion of the suction hole on the rotor-side end face 4a.
