Abstract
A scroll compressor may include an oil supply passage formed in a main frame. A first end of the oil supply passage may be open toward an orbiting space of the main frame and a second end may be open toward an Oldham ring. With this configuration, even if refrigerant suctioned through a refrigerant suction pipe sweeps away oil, which lubricates a sliding surface between a key and a key groove adjacent to the refrigerant suction pipe while passing through between the key and the key groove, oil may be quickly and smoothly supplied to the sliding surface. This may prevent wear between the key and the key groove so as to enhance efficiency of the compressor.
