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.

Abstract: A rotary compressor includes a cylinder, a drive unit, a piston, a vane, and an oil passage. The cylinder includes a suction chamber for suctioning fluid and a compression chamber for compressing fluid. The drive unit rotates a drive shaft by connecting to the cylinder. The piston oscillates in the cylinder by connecting to the drive shaft. The vane extends between the cylinder and the piston so as to separate the suction chamber from the compression chamber, and some parts of the length of the vane are inserted into a slide groove formed in the cylinder. One end of the vane is connected to the coupling groove formed in the piston. The oil passage is disposed between one end of the vane and the rolling piston so as to receive oil therethrough.

Abstract: Disclosed is a compressor having a torque load reducing unit for moving a center of weight to which a gas force is applied. As the torque load reducing unit is formed at an oval-shaped roller, a distance between a rotation center of the roller and an operation point to which a gas force is applied becomes short. This can reduce a torque load to the roller, and can enhance compression efficiency.
