Abstract
A scroll machine has a drive that incorporates radial compliance. The radial compliance is achieved by having the crank pin drive a drive bushing via a flat surface on the crank pin which slidably engages a flat bearing insert disposed in the wall of a bore located in the drive bushing. The bore in the drive bushing is slightly oval in cross-sectional shape to permit relative sliding movement between the crank pin and the drive bushing.
