Abstract
Disclosed are a hermetic compressor and a refrigeration cycle device having the same. An oil separator for separating oil from a refrigerant is installed outside a casing. The oil separated by the oil separator is recollected into the casing by an oil pump driven by a driving force of a driving motor. The oil is recollected from the refrigerant and fabrication costs are be reduced. A cooling capability of the refrigeration cycle device is enhanced, the compressor has a simplified configuration, and the fabrication costs are reduced. Because an outlet of a discharge opening through which oil is discharged to the casing from the oil pump is installed at a position lower than a minimum level of oil in the casing, the refrigerant is prevented from backflowing into an oil passage, and the occurrence of air bubbles on the surface of oil in the compressor may be prevented.
