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.

Abstract: Provided is a scroll compressor. The scroll compressor includes a reinforcing unit between an outlet end of a suction port and an outer circumferential surface of the fixed wrap facing the outlet end of the suction port. The reinforcing unit may overlap a part of the outlet end of the suction port in a radial direction when being projected in an axial direction. Accordingly, rigidity of a suction side of the fixed wrap is increased, and thus, deformation of the suction side of the fixed wrap during operation of the scroll compressor may be suppressed to increase reliability of the scroll compressor.
