Abstract:
An enclosed scroll compressor comprising:a compression mechanism having a fixed scroll, an orbiting scroll, an Oldham ring and a fixing member, the surface of said Oldham ring being formed of a material that is different than the material used to form said fixing member and said orbiting scroll: anda motor for driving said orbiting scroll for moving said orbiting scroll in an orbiting motion for compressing a refrigerant between said fixed scroll and said orbiting scroll;said refrigerant including at least one of Hydro-Fluoro-Carbon and Fluoro-Carbon,said Oldham ring resting on said fixing member and supporting said orbiting scroll to allow said orbiting scroll to make an orbiting motion without rotating about said fixed scroll when said orbiting scroll is driven by said motor, said Oldham ring sliding on both said fixing member and said orbiting scroll,said Oldham ring having a physically-deposited inorganic material surface layer, andsaid inorganic material surface layer being of a material that is different than the material used to form the surfaces of said fixing member and said orbiting scroll,wherein said physically-deposited inorganic material is ceramic.
