Abstract: A compressor according to the present invention comprises a hinge recess formed at a rolling piston and a hinge protrusion formed at a vane to be inserted into the hinge recess. A diameter of the hinge protrusion is greater than an interval between both ends of an opening of the hinge recess. A bearing surface, which comes in contact with an inner circumferential surface of the hinge recess, of an outer circumferential surface of the hinge protrusion, has a circumferential surface below 90° at both sides, respectively, based on a central line in a lengthwise direction of the vane. This structure may facilitate for cutting and grinding the bearing surface so as to reduce a machining cost, and also improve a machining degree and thus stabilize behaviors of the rolling piston and the vane so as to enhance compression efficiency.

Abstract: The present disclosure may provide a compressor in which an outer circumferential side cross-sectional area of a vane slot is formed to be smaller than an inner circumferential side cross-sectional area thereof to decrease an area receiving a force in a roller direction by a vane so as to reduce a contact force between the roller and the vane, and a gas accommodation portion capable of selectively forming a suction pressure and an intermediate pressure is formed between the vane and the vane slot to appropriately control a contact force between the vane and the roller, and a contact surface of the vane facing the roller is broadly formed at a side of a compression chamber to appropriately reduce a contact force between the roller and the vane, and a space portion forming a discharge pressure is formed at least either one side of a side surface of the vane and a cylinder corresponding thereto to decrease a side directional reaction force applied to the vane, thereby reducing a mechanical friction loss between the vane and the cylinder.

Abstract: Disclosed is a compressor. A lubrication surface, which has the same curvature as an inner circumferential surface curvature of a cylinder and which has a predetermined circumference length, is formed on an outer circumferential surface of a roller contacting an inner circumferential surface of the cylinder. With such a configuration, since the outer circumferential surface of the roller contacting the inner circumferential surface of the cylinder come in surface-contact with each other, an oil film is formed between the roller and the cylinder with a wide area. This can reduce a frictional loss.
