Abstract
A swing-link radial compliance mechanism for scroll compressors which minimizes the damage and wear caused by chattering vibrations. The eccentric crankpin has a planar surface and a wedge is disposed in the bore of the roller, between the planar surface of the crankpin and the arc surface of the roller. The wedge has a flat surface for transferring chattering vibrations focused on an axial line of force to the planar surface of the crankpin. Also, an arcuate surface of the wedge engages the arc surface of the roller and allows for rocking movement of the wedge.
