Abstract
The present invention relates to a scroll compressor, with an oil-separating drive shaft, that comprises a housing a fixed scroll which is installed inside the housing, a orbiting scroll which orbits around the fixed scroll, and a drive shaft which drives the orbiting scroll. In the orbiting scroll, a discharge hole is formed. A discharge path is formed along the longitudinal direction of the drive shaft so that discharged coolant from the discharge hole flows therethrough. At least, a part of the discharge path is inclined forward from the rotary axis to the exterior. A lubrication hole is formed in the drive shaft that penetrates from the discharge path to the outer surface of the drive shaft.
