Abstract:
A vane-type compressor is provided. The vane-type compressor may include a cylindrical cylinder having opposite open ends along an axial direction, an inner circumferential surface of the cylinder being eccentric from an outer circumferential surface of the cylinder, a main bearing and a sub bearing, respectively, positioned at the open ends of the cylinder, a rotor coupled to a shaft supported by the main bearing and the sub bearing and installed eccentric from the inner circumferential surface of the cylinder, and a plurality of vanes coupled to the rotor to rotate along with the rotor, the plurality of vanes dividing the inner circumferential surface of the cylinder into a plurality of spaces including a suction chamber and a compression chamber when the rotor rotates. An elastic member may be installed at a point at which a minimum gap is maintained between the inner circumferential surface of the cylinder and the rotor so that a portion of the elastic member protrudes inward of the inner circumferential surface of the cylinder. An end of a discharge dimple formed in the inner circumferential surface of the cylinder extends up to the point.
