    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.

    Abstract: A compressor is provided having an accumulator that forms an accumulating chamber in an internal space of a shell of the compressor, reducing a size of the compressor and simplifying an assembly process. A stationary shaft having a refrigerant suction passage may be directly connected to the accumulator to prevent leakage of refrigerant. Further, a center of gravity of the accumulator may correspond to a center of gravity of the compressor to reduce vibration noise of the compressor caused by the accumulator. Furthermore, both ends of the stationary shaft may be supported by a frame to reduce compressor vibration without using a separate bearing. An installation area of the compressor including the accumulator may be minimized to enhance design flexibility of an outdoor device employing the compressor and minimize interference with other components, thereby facilitating installation of the outdoor device.

    Abstract: Rotary compressor including a cylinder (400), a drive unit, a piston (300), a vane (500), and an oil passage (F). The cylinder includes a suction chamber (410) for suctioning fluid and a compression chamber (420) for compressing fluid. The drive unit rotates a drive shaft (230) by connecting to the cylinder (400). The piston (300) oscillates in the cylinder by connecting to the drive shaft (230). The vane (500) extends between the cylinder (400) and the piston (300) 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 (450) formed in the cylinder. One end of the vane is connected to the coupling groove (390) formed in the piston. The oil passage (F) is disposed between one end of the vane (500) and the rolling piston (300) so as to receive oil therethrough.
