Claims

[Scope of utility model registration request]

a cam ring with both end faces closed by side blocks; a rotor rotatably disposed within the cam ring; a plurality of vanes slidably fitted in vane grooves of the rotor; and the one side. a front rod that is disposed opposite to the side opposite to the cam ring of the block and defines a suction chamber between these opposing surfaces; a control member that is displaceably attached to the suction port of the one side block; and a control member that drives the control member. and a driving means for compressing the fluid by changing the volume of the compression chamber defined by the side block, rotor, and vane, and for starting compression of the suction port by the control member. In a vane type compressor in which the discharge capacity can be variably controlled by changing the position, the control member is slidably held in the circumferential direction between the front head and the one side block, and A toothed portion for being driven is carved on the outer peripheral surface, a toothed portion that meshes with the toothed portion is provided on the output shaft of the driving means, and the control member is directly driven by the driving means. Features a vane type compressor.
