    摘要： 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.

    摘要： 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.

    摘要： There is disclosed a scroll compressor according to the present disclosure in which a discharge port is formed at a central portion thereof, and a pair of two compression chambers continuously moving toward the discharge port are formed, and a plurality of bypass portions are formed at each interval along a movement path of each compression chamber in the both compression chambers, and compression gradients of the both compression chambers are formed to be different from each other, wherein when an interval between a bypass portion closest to the discharge port and another bypass portion adjacent to the bypass portion among the bypass portions of each compression chamber is defined as a first interval, respectively, a first interval of a second bypass portion belonging to a compression chamber having a relatively larger compression gradient is formed to be smaller than that of a first bypass portion belonging to the other compression chamber between the both compressor chambers.

    摘要： A scroll compressor is disclosed, which comprises an auxiliary discharge path capable of sufficiently making sure of a discharge area at an initial discharge stage. The compressor comprises a fixed scroll including a fixed end plate portion and a fixed wrap, and an orbiting scroll including an orbiting end plate portion and an orbiting wrap, wherein a discharge hole is formed in the fixed end plate portion, and an auxiliary discharge path for connecting a side of the orbiting wrap with a bottom surface of the orbiting wrap is provided to be communicated with the discharge hole, whereby a compressed refrigerant may be discharged through the auxiliary discharge path.

    摘要： A compressor is provided that may include a passage separator provided between an electric motor drive and a compression device to separate a refrigerant passage from an oil passage. The passage separator may include a first partition wall and a second partition wall. The first partition wall may be disposed between an inner circumferential surface of a casing and a discharge hole of the compression device, and the second partition wall may be disposed between the discharge hole and a balance weight. Accordingly, the refrigerant passage may be separated from the oil passage between the compression device and electric motor drive, thereby efficiently recovering oil to an oil storage space.
