摘要： A hermetic compressor includes a hermetic container, a compression element accommodated in the hermetic container, and a motor element driving the compression element. The hermetic container has an inner space therein arranged to store lubrication oil. The compression element includes a shaft unit rotating about a rotation axis. The shaft unit has an oil-feeding passage provided therein. The oil-feeding passage extends upward from a lower end of the shaft unit. The shaft unit has an oil-spattering hole provided therein. The oil-spattering hole extends substantially perpendicularly to the rotation axis. The oil-spattering hole has a first open end communicating with the oil-feeding passage and a second open end opening in the inner space of the hermetic container. The second open end has a cross-sectional area smaller than a cross-sectional area of the first open end. This hermetic compressor supplies lubrication oil to sliding component, such as a piston, of the compression element, thus operating reliably and efficiently.

摘要： A hermetic compressor has a bipolar permanent magnet motor where permanent magnet (124) is disposed in rotor core (123). Hollow bore (131) is disposed at the end on the compressing element (105) side of rotor core (123), and main bearing (111) extends into bore (131). The thickness of rotor core (123) is longer than that of stator core (126), thereby widening the magnetic path of rotor core (123). The magnetic flux amount generated in rotor core (123), which is conventionally insufficient due to existence of bore (131), increases, the loss decreases, and the efficiency increases.

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： The present invention provides a refrigerant compressor which may assure excellent reliability while using low-viscosity refrigerant. The refrigerant compressor is characterized in that the viscosity of oil stored in hermetic container ranges from VG3 to VG8, and the boiling component at 350 C or over is not less than 10% and not higher than 30% in volume ratio, and the boiling component at 300 C or less is not less than 50% and not higher than 70% in volume ratio. Accordingly, the input reduction at sliding surfaces can be realized, and the lubricant is evaporated, therefore it is possible to prevent defective compression caused by PET (polyethylene phthalate) or the like deposited on the surfaces of the discharge reed and the like, and to enhance the efficiency and reliability.
