PROBLEM TO BE SOLVED: To provide a vane compressor capable of achieving manufacturing cost reduction and size reduction.SOLUTION: A vane compressor of the present invention includes a valve case 47 provided synchronously rotatably in a drive shaft 7. In this valve case 47, a communication path 47a, a guide hole 47b, and the like are formed, and a spool valve 49 and a coil spring 51 are included. A valve element internal path 49e is formed in the spool valve 49. In this vane compressor, the spool valve 49 moves in the guide hole 47b in a direction away from a center O of the drive shaft 7 that serves as a rotational shaft against an urging force of the coil spring 51 as a rotational speed of the drive shaft 7 rises. A communication area between the communication path 47a and the valve element internal path 49e thereby decreases in the valve case 47. |
