Abstract
In a sealed electric scroll compressor, lubricating oil is collected in an oil collection pan mounted under a compression mechanism after the compression mechanism is lubricated thereby, the lubricating oil collected in the oil collection pan is discharged from a small hole at the side of the oil collection pan which is located remote from a delivery pipe for delivering a high-pressure refrigerant gas outward from a sealed container of the sealed electric compressor. The high-pressure refrigerant gas flows between the inner wall of the sealed container and a vertical cut part formed on the circumference of a stator of an electric motor.
