    摘要： A rotary compressor includes a compressing unit including: an annular cylinder; an end plate having a bearing unit, and closing an end portion of the cylinder; an annular piston fitted in a rotation shaft in the bearing unit, performing an orbital motion inside the cylinder, and forming an operation chamber with the cylinder inner wall; and a vane protruding from a groove of the cylinder to the operation chamber, coming into contact with the annular piston, and partitioning the operation chamber into an inlet chamber and a compression chamber. The vane is formed of steel and has a diamond-like carbon layer on a sliding surface with respect to the annular piston. The annular piston is formed of Ni—Cr—Mo cast iron to which 0.15 wt % to 0.45 wt % of phosphorus is added, or formed of cast iron or steel, and has an iron nitride layer on its outer circumferential surface.

    摘要： A rotary compressor includes a sealed vertical compressor housing, a compressing unit, and a motor. A refrigerant discharging unit is provided at an upper part and a refrigerant intake unit is provided at a lower part side surface in the sealed vertical compressor housing. The compressing unit is disposed on the lower part of the compressor housing, includes an annular cylinder, an end plate including a bearing unit and a discharge valve unit and blocking end portions of the cylinder, an annular piston that engages with an eccentric portion of a rotation axis supported by the bearing unit, revolves along a cylinder inner wall of the cylinder in the cylinder, and forms a cylinder chamber between the cylinder inner wall and the annular piston, and a vane. The motor is disposed on the upper part of the compressor housing, and drives the compressing unit via the rotation axis.
