Patent abstract
A single-winding multi-stage expander comprises a fixed scroll and an orbiting scroll which revolves eccentrically with respect to the fixed scroll so as to pressurize a sealed chamber formed between the two scrolls to drive a crankshaft. A high-temperature pressurized gas is introduced into a first-stage inner division and sent to an external heater. The heated gas is sent back to a second-stage outer division of the expander to significantly increase efficiency thereof.
