摘要： A hermetic compressor, includes: a hermetic container storing a lubricating oil; an electric motor; a drive shaft; a compression mechanism; a rotary pressure increasing mechanism increasing pressure of refrigerant gas; a cylindrical lateral wall partitioning a space above the electric motor into outer and inner spaces; and a discharge pipe allowing refrigerant to flow out from the inner space into an external circuit. The refrigerant gas discharged from the compression mechanism into the hermetic container is moved from a space below the electric motor up to an upper end of the rotator through rotator vents of the rotator, flows into the rotary pressure increasing mechanism to be increased in pressure, flows into the inner space to increase a pressure in the inner space, and is discharged to an outside through the discharge pipe while suppressing inflow of the refrigerant gas from the outer space to the inner space.

An oil discharge passage communicating with the oil supply hole is formed by a flat surface or a recessed surface at a portion of the outer peripheral surface of the drive shaft. A trailing edge of the oil discharge passage is displaced behind a trailing edge of the oil supply hole with respect to a rotation direction of the drive shaft. A leading edge of the oil discharge passage is displaced behind a leading edge of the oil supply hole with respect to the rotation direction of the drive shaft. The oil discharge passage has a width that is no larger than a diameter of the oil supply hole.
