ABSTRACT:
To present a compressor for refrigerating machine excellent in lubricating effect, small in wear of contact portions, outstanding in refrigerating performance, and high in reliability, in a compressor using HFC refrigerant not containing chlorine atom. A lubricating oil containing HFC refrigerant, an ester compound oil as principal component, and a phosphoric acid triester as extreme pressure additive is used. Moreover it is composed so that the surface hardness of a vane for composing the contact portions of the compressing mechanism and the surface hardness of the piston may have a difference of 10 or more in Rockwell hardness (HRC). As the extreme pressure additive, also, phosphite, phosphoric acid diester or phosphoric acid monoester can be used. As the principal component of lubricating oil, ether compound oil or carbonate compound oil is also usable.
