ABSTRACT:
In a suction port for a vane-type compressor in which suction holes 15a and 15 a along the inner peripheral edge 1a of the cylinder 1 are disposed in the read side block 4 and notch portions 15b and 15b opposing to the suction holes 15a are disposed at the opening edge on he suction side of cylinder 1, the suction holes 15a and 15a are arranged outside the vane sliding zone of the rotor-side end face 4a of the rear side block 4. If a vane juts out of a vane groove, the tip of vane does not enter the suction holes 15a and 15a even if the tip of a vane is inclined, so that the vane does not heavily rub the end portion of the suction hole on the rotor-side end face 4a.
