ABSTRACT:
An eccentric drive pin is located on the overhung end of a crankshaft. The drive pin is located within a bore in a slider block which is located within the hub of an orbiting scroll. Either the drive pin or the slider block bore has an axially curved surface and the other has a corresponding flat surface parallel to the axis of the crankshaft. Contact between the axially curved and corresponding flat surface remains at essentially the same axial location even though the drive pin is deflected under loading.
