Abstract: A compressor is provided that may include a refrigerant flow path provided in a rotational shaft so as to guide a refrigerant gas. The rotational shaft operates a compression device using a drive force of an electric motor. In such a structure, the refrigerant gas may be directly discharged to a discharge space without passing through other portions such that flow path resistance may be minimized.
