ABSTRACT:
A scroll compressor, which allows refrigerant in a compressor chamber to be partially discharged so that frictions generated in frictional surfaces between an orbiting scroll and an Oldham ring and between the Oldham ring and a main frame may be decreased. Also, an upper chamber may be formed on an upper surface thereof and a lower chamber may be formed on a lower surface thereof. An oil supply structure may be provided in a main frame such that lubrication is smoothly performed. Additionally, at least one key may be provided protruding from the lower surface of the Oldham ring. Further, the main frame may include at least one key groove configured to receive the at least one key of the Oldham ring. Additionally, the oil supply groove may be provided separately from and in communication with the at least one key groove.
