摘要： 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.

摘要： A highly reliable reciprocating compressor works efficiently with less energy, and produces smaller vibrations. This reciprocating compressor includes a crankshaft, a block, a piston, a connecting rod, and a balancing weight. The cylinder is placed offset such that an axis line thereof and an axis line of the main shaft do not cross each other. The center of gravity of the balancing weight is placed substantially opposite to the center of the eccentric section with respect to the axis line of the main shaft and deviated along a rotating direction of the main shaft from the place just opposite to the center of the eccentric section. The foregoing construction allows reducing lateral pressure of the piston, thereby increasing the reliability and efficiency of the reciprocating compressor, and allows to cancel unbalancing force produced by motions of the piston, the connecting rod and the eccentric section with motion of the balancing weight.

摘要： 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.

摘要： A hermetic compressor has a bipolar permanent magnet motor where permanent magnet is disposed in rotor core. A hollow bore is disposed at the end on the compressing element side of the rotor core, and main bearing extends into the bore. The thickness of the rotor core is longer than that of the stator core, thereby widening the magnetic path of the rotor core. The magnetic flux amount generated in the rotor core, which is conventionally insufficient due to existence of the bore, increases, the loss decreases, and the efficiency increases.
