Abstract (en)
[origin: WO2016077909A1] The orbiting scroll thermal exchange engine, expanding screw thermal exchange engine, and the sliding vane thermal exchange engine are three similar utility designs producing work with the expansion and contraction of a gas, leveraged by the phase change of a liquid contained in chambers that change in volume. Multiple working chambers are formed inside a vessel, carrying a quantity of liquid and gas, prescribed for the temperature range anticipated. Adjacent to each chamber the conduction of thermal energy into the vessel is changing the internal pressure and moving each chamber as it is changing in volume. The thermal expansion or contraction is leveraged with the phase change of the liquid, producing torque for the duration of the volume change within each chamber.
