    Abstract: A rotary compressor includes: a compressing unit that includes an annular cylinder, an end plate which has a bearing unit and a discharge valve unit and closes an end portion of the cylinder, an annular piston which is fit in an eccentric portion of a rotation shaft supported in the bearing unit, performs an orbital motion inside the cylinder along a cylinder inner wall of the cylinder, and forms an operation chamber together with the cylinder inner wall, and a vane which protrudes from the inside of a vane groove of the cylinder to the inside of the operation chamber, comes into contact with the annular piston, and partitions the operation chamber into an inlet chamber and a compression chamber. The vane is formed of steel and has a diamond-like carbon layer formed 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 is formed of cast iron or steel and has an iron nitride layer formed on an outer circumferential surface thereof.

    Abstract translation: 一种旋转式压缩机，其特征在于，具备：压缩单元，其具有环状的气缸;端板，其具有轴承单元和排出阀单元，并且封闭该气缸的端部;环状活塞，其嵌合于旋转轴的偏心部 被支承在轴承单元中，沿气缸的气缸内壁在气缸内进行轨道运动，并且与气缸内壁一起形成操作室;以及叶片，其从气缸的叶片槽内突出到 操作室的内部与环形活塞接触，并将操作室分隔成入口室和压缩室。 叶片由钢形成并具有形成在相对于环形活塞的滑动表面上的类金刚石碳层。 环形活塞由添加了0.15wt％至0.45wt％磷的Ni-Cr-Mo铸铁形成，或者由铸铁或钢形成并且在其外周表面上形成有氮化铁层。

    Abstract: A semi-spherical shoe 1 includes an end face 1B which is disposed in sliding contact with a swash plate 3 and a semi-spherical surface 1A which is disposed in sliding contact with a semi-spherical recess 2A formed in a piston 2. A spherical recess 1C is formed in the top portion of the semi-spherical surface 1A to define a space 4 which serves as a reservoir of lubricant oil between the spherical recess 1C and the semi-spherical recess 2B. If the volume of the space 4 which serves as a reservoir of lubricant oil is increased, an accumulation of abraded power in the spherical recess 1C which forms the space can be prevented in a favorable manner.

    Abstract translation: 半球形滑履1包括一个与斜盘3滑动接触的端面1B和一个与形成在活塞2中的半球形凹槽2A滑动接触的半球形表面1A。 在半球面1A的顶部形成凹部1C，在该球面凹部1C和半球面凹部2B之间形成作为润滑油的贮存部的空间4。 如果用作润滑油储存器的空间4的体积增大，则能够以良好的方式防止形成空间的球形凹部1C中的磨损粉末的积聚。
