    Abstract: A compressor is provided. The compressor may include a fixed wrap, and an orbiting scroll having an orbiting wrap engaged with the fixed wrap to form compression chambers. The fixed wrap and the orbiting wrap may have irregular wrap curves. At least one interference avoiding portion at which a spacing between the wraps is greater than an orbiting radius or at least one gap compensating portion at which the spacing between the wraps is smaller than the orbiting radius, in a state in which a center of the fixed scroll and a center of the orbiting scroll are aligned with each other, may be provided on a sidewall surface of the fixed wrap or the orbiting wrap, whereby frictional loss or abrasion due to interference between the wraps or a refrigerant leakage due to a gap between the wraps may be prevented.

    Abstract: 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.

    Abstract: A scroll compressor is provided in which a boss of an orbiting scroll is inserted into and coupled to a boss coupling recess of a crank shaft, so that friction loss of a bearing portion of the crank shaft may be reduced, compression efficiency and reliability of the compressor may be enhanced, and noise and material costs may be reduced. A bush bearing may be formed as a coating on the boss of the orbiting scroll, so that a thickness of the bearing portion of the crank shaft may be reduced. Since an outer circumferential surface of the bearing portion is in contact with an inner circumferential surface of the boss coupling recess, damage to the bearing portion may be prevented.

    Abstract: A motor-operated compressor includes a compression part including a fixed scroll and an orbiting scroll that form a compression chamber configured to compress fluid by an orbiting motion of the orbiting scroll relative to the fixed scroll. A motor part is disposed at one side of the compression part, and configured to generate a drive force to cause the orbiting scroll to make the orbiting motion. A rotary shaft is connected to the motor part and the orbiting scroll to transmit the drive force generated by the motor part to the orbiting scroll. A main frame is disposed between the compression part and the motor part in an axial direction of the rotary shaft, and configured to support the fixed scroll in the axial direction of the rotary shaft. A discharge chamber is formed between the fixed scroll and the main frame, and fluid discharged from the compression part passes through the discharge chamber to outside of the motor-operated compressor.
