Abstract: A refrigerant compressor reserves lubricating oil with a viscosity of VG2 to VG100 in a sealed container, and accommodates therein an electric component and a compression component which is driven by the electric component and compresses a refrigerant. The compression component includes at least one slide member comprising a base material 171 made of an iron-based material and an oxide coating film 170 provided on a surface of the base material 171. The oxide coating film 170 includes: a portion containing diiron trioxide (Fe2O3), in a region which is closer to an outermost surface of the oxide coating film; and a silicon containing portion containing silicon (Si) which is more in quantity than silicon (Si) of the base material 171, in a region which is closer to the base material 171.

Abstract: A synthetic resin film is formed on a region of a valve plate (117) which is brought into contact with an arm portion of a suction valve (120) or a region of the valve plate (117) which is brought into contact with an arm portion of a discharge valve (121). With such a configuration, delay in opening of the suction valve (120) or the discharge valve (121) caused by adhesion force of refrigerating oil is suppressed so that a pressure loss in a suction stroke or a discharge stroke can be reduced whereby compressor efficiency is enhanced. Further, a striking sound generated at the time of closing the suction valve (120) or the discharge valve (121) is reduced by an elastic effect of the synthetic resin film so that the reduction of noises is realized.
