    Abstract: A hermetic type refrigerant compressor operates using a refrigerant and a refrigerator oil in which the refrigerant is soluble. The refrigerant compressor includes slidable members adapted to slidably move and a compressing mechanism for compressing the refrigerant with the aid of the slidable members in a hermetic casing. The refrigerant, the refrigerator oil and the slidable members are selected and constructed in the following manner. The refrigerant is a 1,1,1,2-tetrafluoroethane or a 1,1-difluoroethane, the refrigerator oil is at least one kind of refrigerator oil selected from a polyalkylene glycol based oil and a polyester based oil, and at least one of the slidable members has a slidable surface which is prepared such that a surface hardened layer (12) having a Vickers hardness of 400 or more and a thickness of 2 microns or more is formed on a substrate (11) of ferrous metallic material, and subsequently, an iron oxide layer (13) composed of Fe₃O₄ as a main component and having a thickness of 0.01 micron or more is formed on the surface hardened layer. Each slidable member has surfaces each of which exhibits especially improved abrasion resistance.

    Abstract: A closed-type compressor includes a closed casing accommodating an electric motor from which a rotational shaft extends and a compressing machine to be operated by the motor and the compressing machine is of a reciprocating-type and provided with sliding portions. A hydrofluorocarbon (HFC) refrigerant is used as a compressor refrigerant, and a refrigerator oil consisting essentially of ester is used as a lubricating oil. The sliding portions of the compressing machine each is formed of two members one of which is made of cast iron subjected to an insoluble film forming process using manganese phosphate and another one of which is made of carbon steel.

    Abstract: An object is to provide a highly efficient compressor while improving a refrigerant leakage, enhancing a performance of a compressor, improving durability, and enhancing reliability. The compressor comprises: a compression element comprising a cylinder in which a compression space is constituted; a suction port and a discharge port which communicate with the compression space in the cylinder; a support member which closes an opening of the cylinder; a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member; a compression member whose one surface crossing an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and which is disposed in the cylinder to be rotated by the rotary shaft and which compresses a fluid sucked from the suction port to discharge the fluid via the discharge port; a vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member and which partitions the compression space in the cylinder into a low pressure chamber and a high pressure chamber; and a shaft seal which is disposed on an end portion of the bearing (main bearing) on a side opposite to the compression member and which abuts on the rotary shaft.
