Patent ID: 7175402

Claim:
An eccentric coupling device in a radial compliance scroll compressor, the eccentric coupling device comprising: a crank pin eccentrically positioned at an upper end of a crankshaft included in the scroll compressor, and provided with a vertically-extending flat surface at one side of the crank pin; a bush provided with a crank pin hole configured to receive the crank pin, and a stopper hole provided in the bush at one side of the crank pin hole such that the stopper hole overlaps with the crank pin hole; a stopper fitted in the stopper hole such that the stopper radially protrudes into the crank pin hole toward the flat surface to selectively come into contact with the flat surface in accordance with a rotation of the bush; and an elevation preventer configured to elastically support the bush, while connecting the stopper and the crank pin via a spring wire, thereby preventing an elevation of the bush, one end of the spring wire being fixedly mounted to the crank pin, the spring wire being engaged with a peripheral surface of the stopper, the other end of the spring wire being movable, the spring wire elastically supporting the stopper.
