ABSTRACT:
An eccentric coupling device in a radial compliance scroll compressor includes a crank pin that is eccentrically arranged at an upper end of a crankshaft and provided with a vertically-extending flat surface at one side thereof. A bush is provided with a crank pin hole, overlapped by a stopper hole, for receiving the crank pin. A stopper is 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. An elevating preventing device is adapted to elastically support the bush, while connecting the stopper and the crank pin via a spring wire, preventing an elevation of the bush.
