Abstract
A vane compressor includes a cylinder, a rotor portion, vanes, and a first discharge port allowing a refrigerant in a compression chamber to be discharged therethrough. The vanes are disposed inside the rotor portion and held rotatably about the center of a cylinder inner circumferential surface, partition a space between the cylinder inner circumferential surface and the rotor portion, and form the compression chamber. A second discharge port is disposed at a location having a phase angle smaller than that at the first discharge port, being open to the cylinder inner circumferential surface, and communicating with the compression chamber. The second discharge port includes an opening portion to the compression chamber, 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.
