The system includes a heat exchanger 2 within which hot fluid from chamber 1 and cold fluid from chamber 3 is circulated in opposite directions and then fed back to chambers 3, 1 respectively. Fluid enters the expansion chamber 1 through a heater 17 and a valve 13 and displaces piston 8 to the left. After a predetermined movement of the piston valve 13 closes and the fluid expands in chamber 1, which is heated externally, further displacing the piston 8 until a spring 11 is capable of opening a valve 9 in the piston. Hot fluid then passes through circuit B of the heat exchanger to the compression chamber 3 via a cooler 28. During the displacement of piston 8 to the left, fluid already in chamber 3, which is cooled externally, is compressed by piston 19 until a valve 23 opens and allows it to pass to circuit 19 of the heat exchanger. Under the action of springs 30, 31 the pistons then move to the right. Valves 9, 13 open and close respectively and the fall in pressure in chamber 3 allows valve 23 to close. The pressure of the fluid from the cooler 28 opens a valve 20 in piston 19 and the chamber 3 fills until the fluid pressure therein closes valve 20. The cycle then repeats.
