ABSTRACT:
A centrifugal heat engine comprises a first member rotatably mounted on a second member. The first member has an annular chamber on its periphery containing a vaporizable working fluid, and a central chamber separated from the annular chamber by a bulkhead. The central chamber contains an operating liquid and an hydraulic turbine mounted on the second member which projects into the central compartment and divides the same into two axially displaced compartments each of which contains operating liquid. The working fluid in the annular chamber is heated and vaporized. A conduit conducts vaporized working fluid in the annular chamber into one of the compartments wherein the vaporized working fluid expands in the operating liquid producing a liquid/gas mixture in the one compartment. Rotation of the first member creates a pressure differential between the two compartments that is related to the rotational speed of the first member and the density distribution of the fluids in the two compartments. The turbine contains a structure in cooperation with the first member for effecting a fluid path for the operating fluid between the two compartments such that rotation is imparted to the first member.
