Abstract:

This vane-type compressor (200) is provided with: a cylinder (1); a rotor part (4a); vanes (5a, 6a) which are arranged in the rotor part (4a), are supported to allow rotation around the center of the cylinder inner peripheral surface (1b), partition the space formed between the cylinder inner peripheral surface (1b) and the rotor part (4a), and form a compression chamber (11); and a first discharge port (1d) which discharges a refrigerant in the compression chamber (11). Further, a second discharge port (1e) which opens to the cylinder inner peripheral surface (1b) and communicates with the compression chamber (11) is formed in a position with a phase angle smaller than that of the first discharge port (1d), and the width in the circumferential direction of the opening in said second discharge port (1e) that faces the compressor chamber (11) is no wider than the tip of the vanes (5a, 6a).
