Abstract
The present disclosure relates to is a compressor. The compressor may be provided with a communication hole between an inlet and an outlet of a refrigerant discharge pipe coupled through an upper surface of a casing, the communication hole penetrating between an outer circumferential surface and an inner circumferential surface of the refrigerant discharge pipe. Thus, during oil sealing through the refrigerant discharge pipe, a flux path area of a driving motor may be ensured, and a number of winding wires and/or a coil diameter of a stator coil may be ensured. Thus, efficiency of the driving motor may be maintained and backflow or overflow of oil through the refrigerant discharge pipe may be suppressed. In addition, during operation of the compressor, oil may be suppressed from being excessively leaked through the refrigerant discharge pipe without having to include a separate oil separator inside or inside the casing.
