Abstract
A slide vane type compressor comprises a cam ring formed with at least one working chamber and a rotor arranged in the at least one working chamber with an outer peripheral surface of the rotor being disposed close to an inner wall surface of the cam ring at least at one axial sealing portion thereof, with the rotor being formed vane grooves for respectively accommodating a plurality of vanes. At least one suction port introduces gas into the at least one working chamber, with the suction port having a suction terminal point angle extending from the axial sealing portion to a terminal point of the suction port, as viewed in the direction of rotation of the rotor. The suction terminal point angle of the suction port is greater than a geometrical suction terminal point angle geometrically determined in dependence upon the number of working chambers and the number of the plurality of vanes so that the suction terminal point angle of the suction port is advanced as compared with the geometrical suction terminal point angle.
