<p>An engine has a chamber (3) accommodating a rotor (5) providing shaft power from the expansion in the chamber (3) of a refrigerated or compressed drive fluid admitted to the chamber (3). A heat-exchange liquid is also admitted to the chamber (3). The heat-exchange liquid gives up heat energy to the expanding drive fluid in the chamber (3), and the cooled heat-exchange fluid is withdrawn from the chamber by a return pipe (16), passed through a heat exchanger (20) to raise its temperature to ambient and then reintroduced into the chamber (3).</p> |
