Abstract
Peripherally-driven scroll apparatus. The orbiting scroll member is attached through radially-compliant linking means to eccentrics mounted on three equally spaced crankshafts to accommodate differential thermal expansion without the generation of any appreciable elastic forces to increase bearing loads. Means are provided to prevent axial deflections in the stationary scroll members while permitting their supports to be designed and constructed for strength rather than stiffness. The apparatus may be staged and employed as a compressor or expander.
