    Abstract: A refrigerant compressor includes a first layer (24) composed of a single layer of chromium, a second layer (25) composed of an alloy layer of chromium and tungsten carbide, a third layer (26) composed of an amorphous carbon layer containing at least one of tungsten and tungsten carbide, and a fourth layer (27) composed of an amorphous carbon layer containing carbon and hydrogen without metals, which are sequentially formed on a surface of a sliding member (13b) of a compression mechanism formed of tool steel. The second layer (25) is formed to have a chromium content higher on a side of the first layer (24) than a side of the third layer (26), and have a tungsten carbide content higher on the side of the third layer (26) than the side of the first layer (24)- In addition, the third layer (26) is formed to have a tungsten content or a tungsten carbide content higher on a side of the second layer (25) than a side of the fourth layer (27).

    Abstract: A variable displacement compressor optionally varies displacement based upon pressure in a crank chamber for adjusting the pressure in the crank chamber by varying an opening degree of a passage that interconnects the crank chamber and one of relatively high and low pressure regions of the refrigeration cycle. A control valve of the variable displacement compressor has a valve seat and a valve. The valve seat has a seat surface for adjusting the opening degree of the passage. The valve has a valve surface for adjusting the opening degree of the passage. At least one of the seat surface and the valve surface is made of a material with relatively high hardness.

    Abstract: A piston (1) for an internal combustion engine has a piston-ring groove (2) which is strengthened with a composite layer (3) based on porous metal which is embedded around the piston-ring groove (2). The porous metal contains at least 10% Cr, and the volumetric ratio of the porous metal is between 8 to 70%, so that even when the engine is operated under high heat loads, no crack will be initiated in the piston (1).

    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.
