    摘要: 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.

    摘要: A fluid compressor includes a case, a fixed scroll, an orbiting scroll, a motor, and at least one anti-rotation unit. The case is configured to form an external appearance thereof. The fixed scroll is fixed in the case. The orbiting scroll is engaged with the fixed scroll at one side of the fixed scroll, and performs partitioning of a compression chamber. The motor provides the orbiting scroll with drive power. The anti-rotation unit is coupled to a side surface of the orbiting scroll so as to prevent rotation of the orbiting scroll.

    摘要: An oil level detecting device for a compressor and an air conditioning system having the same are provided. The oil level detecting device may be provided in a compressor including a compression device that introduces and compresses a working fluid, a driving device mechanically connected to the compression device that operates the compression device, and a case that accommodates the compression device and the driving device thereinside and having an oil storage space that stores oil at a lower portion thereof. The oil level detecting device may include a detector including a supporting portion configured to be attached to the case and a detecting portion that protrudes inside the case. At least one property of the detecting portion may vary according to an oil level inside the case. The oil level detecting device may also include a signal processor including an electronic element having at least one reference property. The signal processor may compare the at least one property of the detecting portion with the at least one reference property of the electronic element and outputs a control signal according to the result.

    摘要: Disclosed herein is a thrust bearing for a turbo compressor, the thrust bearing has a structure that is modified in response to a portion where a deformation amount of a thrust runner is relatively large on the basis of magnitude of a force applied at the time of rotation of a shaft of a turbo compressor, to maintain a thickness of an oil film constantly and to increase a load supporting force of the thrust bearing, thereby ensuring improved durability of the thrust bearing.
