<P>PROBLEM TO BE SOLVED: To provide a reliable refrigerant compressor using low viscosity lubricant. <P>SOLUTION: Reliability is improved since abnormal wear due to breakage of oil film created by evaporation of lubricant at a sliding part can be prevented by using ion liquid 103 of which evaporation temperature is 400°C-1000°C as lubricant stored in a hermetic vessel 101 and compression failure caused by deposition of PET (polyethylene terephthalate) or the like on a surface of a delivery lead 120 or the like due to evaporation of lubricant can be prevented. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
