Abstract
A scroll machine having an eccentric crank pin on a cranshaft disposed nonrotatably in the bore of a drive busing for driving the orbiting scroll of the compressor. A flat on the crank pin drivingly engages a flat in the bore, one flat being at an acute angle to the normal cranksahft axis so that when the crankshaft deflects under normal loads the flats come into better contact with one another to reduce unwanted wear. Several other embodiments are also disclosed.
