Abstract
A compressor is provided that includes an accumulator formed in an internal space of a shell to reduce a size of the compressor. An accumulator space may be formed using the shell of the compressor, thereby simplifying an assembly process. A stationary shaft having a refrigerant suction passage may be directly connected to the accumulator to prevent leakage of refrigerant. A discharge passage may be formed in a rotating body to enhance a cooling effect of a drive motor, and an oil separating member may be installed in the discharge passage to prevent oil from being excessively leaked out. A center of gravity of the accumulator may correspond to a center of gravity of the compressor to reduce vibration noise of the compressor caused by the accumulator. An area for installing a compressor including the accumulator may be minimized to enhance design flexibility of an outdoor device.
