Abstract: Relating to oil feed to a piston portion in a dual support bearing of a hermetic compressor, and a structure for improving efficiency and reliability and accomplishing reduction of noise is disclosed. In this structure, since an auxiliary bearing 119 is provided with an oil feed passage 129 for conducting lubricating oil 108 discharged from an upper end of an oil feed mechanism 114, to a sliding surface of a piston 120, the lubricating oil 108 is fed to the piston 120 and a piston pin 122 from the oil feed passage 129 to make the sealing performance excellent, so that the amount of leakage of refrigerant gas from a compression chamber 117 is reduced to improve the freezing capability or efficiency. Further, lubrication of sliding portions of the piston 120 and the piston pin 122 becomes excellent so that noise caused by sliding is reduced and the reliability is improved.

Abstract: A compressor includes a sealed casing (2) which accommodates therein a compressing unit (6) for compressing a refrigerant and a driving unit (7) for driving the compressing unit. An induction pipe (18) is provided in the sealed casing for introducing the refrigerant into the compressing unit. The induction pipe has an outlet end communicating with the interior of the compressing unit and an inlet end which is opened to space in the sealed casing at a position which may correspond to a node of a standing wave of the refrigerant in the sealed casing.

Abstract: A refrigerant compressor includes a compressor section, driver, a first contact section and a second contact section. The compressor section is accommodated in a closed container for compressing refrigerant gas. The driver drives the compressor section. The first and second contact sections are brought into contact with each other or they slide with each other by driving the compressor section. On the surface of each one of the contact sections, at least one of plural recesses uniformly placed or a mixed layer, to which molybdenum disulfide (MoS2) is bound, is formed. The foregoing structure allows increasing the abrasion resistance of the first and second contact sections.
