摘要： A vane compressor (200) includes a cylinder (1), a rotor portion (4a), vanes (5a and 6a), and a first discharge port (1d) allowing a refrigerant in a compression chamber (11) to be discharged therethrough. The vanes (5a and 6a) are disposed inside the rotor portion (4a) and held rotatably about the center of a cylinder inner circumferential surface (1b), partition a space between the cylinder inner circumferential surface (1b) and the rotor portion (4a), and form the compression chamber (11). A second discharge port (1e) is disposed at a location having a phase angle smaller than that at the first discharge port (1d), being open to the cylinder inner circumferential surface (1b), and communicating with the compression chamber (11). The second discharge port (1e) includes an opening portion to the compression chamber (11), the opening portion having a width in the circumferential direction, the width being equal to or smaller than the width of the tip of each of the vanes (5a and 6a).

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.
