機。 A cam ring whose both sides are closed by side blocks, a rotor rotatably disposed within the cam ring, and a vane slidably fitted into a vane groove of the rotor, the side block, the cam ring, In a vane type compressor that compresses fluid by varying the volume of a cavity defined by a rotor and vanes, the volume of the cavity divided by the vanes on the inner circumferential wall of the cam ring is The circumferential suction port is opened at the maximum position, and the vane is located on the front side in the rotational direction of the rotor from the circumferential suction port and is located on the sliding surface side of the one side block that contacts the rotor. The side suction port is opened at a position where the volume of the void chamber divided by the side suction port is maximum, and an opening/closing member for opening and closing the side suction port is slidably provided on the one side block, and the opening/closing member is moved by a biasing member. The opening/closing member is provided with a pressure receiving member that receives the dynamic pressure of the fluid to be compressed on the inflow side, and the opening/closing member is biased in the direction of closing the side suction port by the action of the dynamic pressure during high-speed operation. A vane type compressor, characterized in that the suction port closing angle is increased by sliding the side suction port in the opening direction against the biasing force of the biasing member.
