Abstract
An engine has a chamber () accommodating a rotor () providing shaft power from the expansion in the chamber () of a refrigerated or compressed drive fluid admitted to the chamber (). A heat-exchange liquid is also admitted to the chamber (). The heat-exchange liquid gives up heat energy to the expanding drive fluid in the chamber (), and the cooled heat-exchange fluid is withdrawn from the chamber by a return pipe (), passed through a heat exchanger () to raise its temperature to ambient and then reintroduced into the chamber ().
