Abstract
The axial forces acting upon the orbiting scroll of a scroll compressor during operation produce a resultant force which requires a varying, crank angle dependent radius for dynamic equilibrium. The flat plate or floor portion of the orbiting scroll is provided with a varying radius to provide sufficient radius to be acted on by the resultant force. In a preferred embodiment, the radius is only increased beyond the nominal radius for the angular extent necessary and a diametrically located angular extent of reduced radius is provided to make room for other components and/or to reduce friction.
