    摘要： A rotary compressor includes a cylinder having a vane slot and a compression chamber, a shaft having an eccentric portion and configured to perpendicularly pass through a center of the compression chamber, a roller having a coupling groove and configured to orbit in the compression chamber by rotation of the shaft, and a vane having a vane hinge coupled to the coupling groove and a vane body being inserted into the vane slot and configured to divide the compression chamber into a discharge space and a suction space. A shape of the discharge-sided groove close to the discharge space and a shape of the suction-sided groove close to the suction space are asymmetrically formed between the vane hinge and the vane body with respect to the a central axis of the vane.

    摘要： 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.

    摘要： A gas leakage preventing apparatus for a rotary compressor comprises: a cylinder having a cylindrical inner space therein; a rotating shaft having an eccentric portion therein which makes a circular motion in the inner space of the cylinder; a rolling piston inserted into the eccentric portion of the rotating shaft and being linearly contact with an inner wall of the inner space of the cylinder; a vane linear-movably inserted into a vane slot which is formed in the cylinder and dividing the cylinder inner space together with the rolling piston; and fixing units provided in the rolling piston and vane, for restraining a rotary motion of the rolling piston. As a result, it is possible to maximize gas compression efficiency by minimizing leakage of high pressure gas
