Claims

[Scope of utility model registration request]

A cam ring, side plates on both sides of the cam ring, a rotor rotatably housed in the cam ring, and vanes retractably provided on the rotor define a working chamber that sucks in and pumps fluid. In the vane type compressor, the fluid suction port and the fluid discharge port are provided at a forward position in the rotor rotational direction and a rearward position in the rotor rotational direction at a portion where the rotor is closest to the cam ring. an inflow space forming recess having a predetermined shape in the circumferential direction of the outer peripheral surface of the rotor facing the inlet in order to reduce flow path resistance of fluid flowing in from the inlet at a forward position in the rotational direction of the rotor at a portion closest to the cam ring; A vane type compressor characterized by having multiple parts.
