Abstract
In a scroll compressor, a pass hole is formed at a position overlapping with a discharge sector of a discharge hole, where a sector for passing a refrigerant through the pass hole is overlapped with a sector for discharging the refrigerant through a discharge hole. This may prevent over-compression of a refrigerant when the scroll compressor is driven at a low speed. This may enhance efficiency of the scroll compressor in a low speed driving mode and under a low load condition.
