Abstract: A compressor is provided in which an outer circumferential side cross-sectional area of a vane slot is formed smaller than an inner circumferential side cross-sectional area thereof to decrease an area receiving a force in a roller direction by a vane to reduce a contact force between the roller and the vane, and a gas accommodation portion selectively forming a suction pressure and an intermediate pressure is formed between the vane and the vane slot to control the contact force. A contact surface of the vane facing the roller is formed at a side of a compression chamber to reduce the contact force, and a space forming a discharge pressure is formed at at least either one side of a side surface of the vane and a cylinder to decrease a side directional reaction force applied to the vane, thereby reducing a friction between the vane and the cylinder.

Abstract: A hermetic compressor is provided that may include a vane that is inserted into a roller, rotates with the roller, and is pushed out toward an inner circumference of a cylinder by rotation of the roller to divide the compression chamber into a plurality of spaces. The vane may include a body having a sealing surface that contacts the inner circumference of the cylinder and inserted into the roller; and a guide that extends from an axial end of the body in a direction crossing a direction the vane slides out, and that is slidably inserted into a guide groove formed on at least one of the first bearing or the second bearing to restrain the vane from sliding out of the roller toward the inner circumference of the cylinder.
