Abstract: A rotary compressor includes a cylinder (310) with a vane slot (312) at one side thereof and a compression chamber (314) at a central portion thereof, a shaft (230) having an eccentric portion and configured to perpendicularly pass through a center of the compression chamber (314), a roller (340) having a ring shape, provided with a coupling groove (341) at one side of an outer circumferential surface thereof and configured to make orbital movements in the compression chamber (314) by rotation of the shaft, and a vane (350) provided with a vane hinge (351) having a circular arc shape and coupled to the coupling groove (341) and a vane body (352) one side of which is inserted into the vane slot (312) and which is configured to divide the compression chamber (314) into a discharge space (D) and a suction space (S), wherein a central point of the coupling groove (341) and a central axis of the vane body (352) are on a single straight line, and a shape of the discharge-sided groove (353) close to the discharge space and a shape of the suction-sided groove (354) close to the suction space are asymmetrically formed between the vane hinge (351) and the vane body (352) with respect to a central axis of the vane (350).

Abstract: An accumulator fixing device (70) for a compressor includes a bracket body (71), a first arm (72) extending from the bracket body and coupled to an accumulator (50), and a second arm (73) extending from the bracket body and coupled to a housing of a compressor (10). The bracket body (71) has a cavity (71a) formed concavely on one surface facing the compressor (10) to reduce vibration generated and transmitted from the compressor.
