PROBLEM TO BE SOLVED: To provide a high efficiency refrigerant compressor using low-viscosity oil without deteriorating reliability. SOLUTION: A mixture layer 123 of fixed molybdenum disulfide is formed on sliding surfaces of slide parts such as a cylinder bore 113 and a piston 115 of the refrigerant compressor. The molybdenum disulfide cracks with a small friction coefficient, performs solid lubrication action and avoids abnormal abrasion. This makes it possible to use the low-viscosity oil and maintain the reliability and to reduce sliding loss and provide the high efficiency refrigerant compressor. COPYRIGHT: (C)2005,JPO&NCIPI
