Abstract
A scroll compressor has a housing, in which are provided fixed and movable scrolls for cooperatively compressing working fluid containing lubricating oil, an oil chamber storing the oil separated from the fluid, and a drive chamber in which a revolving unit for revolving the movable scroll is arranged. The fixed scroll has a communication passage for supplying the stored oil to the drive chamber. The passage has an oil outlet opening in a drive chamber-side end face of the fixed scroll and located in a position which is periodically covered with a base plate of the movable scroll when the movable scroll revolves. A cut is formed in the base plate of the movable scroll and prolongs a time period over which the outlet is opened. The compressor is suited for use in a refrigeration circuit of an air-conditioning system for a vehicle.
