Abstract: An eccentric bush structure in a radial compliance scroll compressor including an eccentric bush fitted around a crank pin eccentrically provided at an upper end of a crankshaft, crank pin and stopper holes provided at the eccentric bush, and a weight member adapted to increase a weight of the eccentric bush. The stopper hole overlaps with the crank pin hole such that a stopper received in the stopper hole is radially protruded into the crank pin hole toward a vertically-extending cut surface formed at the crank pin to selectively come into contact with the cut surface in accordance with a rotation of the crank pin.

Abstract: Disclosed is an asymmetric scroll compressor. The compressor includes an orbiting scroll possessing a wrap which has an involute curve-shaped configuration, an Oldham ring arranged on a lower surface of the orbiting scroll to prevent the orbiting scroll from being reversely rotated, and a fixed scroll having a wrap which has an involute curve-shaped configuration and is engaged with the wrap of the orbiting scroll such that compression chambers are defined between the wraps of the orbiting and fixed scrolls by rotating motion of the orbiting scroll. The wrap of the fixed scroll further extends within the range of 180° than the wrap of the orbiting scroll in a direction where an involute curve extends.

Abstract: The present invention relates to an overheat protection device for a scroll compressor which can prevent a sealing member from being damaged due to the overheat, by detecting a temperature of an inhaled or discharged gas of the compressor and directly stopping driving of the compressor, without using a special controller, when the gas temperature exceeds an adequate temperature. In the scroll compressor having in a casing an orbiting scroll and a fixed scroll for inhaling, compressing and discharging a gas, and a driving motor for driving the orbiting scroll, an overheat protection device for the scroll compressor stopping the driving motor when a detected temperature exceeds an adequate temperature, a temperature detection device for detecting a temperature of the gas of a low pressure region where the gas is inhaled and a high pressure region where the gas is discharged through a discharge port of the fixed scroll being connected between a power terminal and the driving motor in an electrical serial state.
