VANE-TYPE COMPRESSOR

WIPO Patent Application WO/2015/049905

A1

In the present invention, a vane-type compressor comprises the following: a cylinder (1) that has a cylindrical shape and both axial-direction-ends of which are open; a cylinder head (3) and a frame (2) that close both axial direction ends of the cylinder (1); shaft parts (4a, 4b) the rotational centers of which coincide with the center of the inner circumferential surface (1a) of the cylinder (1) and that rotate inside of the cylinder (1); a vane part (4c) that integrally rotates with the shaft parts (4a, 4b); a rotor (6) the rotational center of which deviates from the center of the inner circumferential surface of the cylinder (1), that is inserted at the periphery of the shaft parts (4a, 4b) via a space, and that rotates inside the cylinder (1); and a bushing (8) that is provided to the rotor (6) and that supports the vane part (4c) so that the vane part is freely rotatable with respect to the rotor (6) and movable in the radial direction of the cylinder (1). The vane part (4c) extends from the shaft parts (4a, 4b), through the bushing (8), and towards the inner circumferential surface of the cylinder (1). The rotor (6) receives transmission of the rotational force of the shaft parts (4a, 4b) via the vane part (4c) and the bushing (8) and is thereby rotated.
