Abstract
A scroll compressor having an extended life due to the support structure for the orbiting scroll, even when using a chlorine-free substitution refrigerant. The support structure includes an Oldham ring for supporting an orbiting scroll so as to allow the orbiting scroll more orbiting motion without rotating about a fixing scroll. The Oldham ring is formed of a different material from both a fixing member and the orbiting scroll. Hence, if a boundary lubrication state occurs in mutually sliding parts, only sliding between different materials occurs, and mutual adhesion in the portion of the boundary lubrication state is avoided. As a result, the shortening of the life due to the wearing of the support structure of the orbiting scroll is prevented.
