Abstract
A hot-gas reciprocating engine comprising at least three piston-like bodies which each separate a hot space and a cold space in the relevant cylinder. Each of the hot spaces communicates, via a regenerator, with one of the cold spaces in another cylinder. Each of the piston-like bodies cooperates, by way of a drive rod, with a plate which is mounted on a rotatable shaft in such a manner that it cannot rotate with respect to this shaft, but can be tilted about a tilting shaft extending transversely of the first-mentioned shaft. Each of the cold spaces communicates, by way of a duct incorporating a control valve, with a cold space in another cylinder. Means for operating these valves are so constructed that, when the valves are opened, these means operate the means for tilting the plate, so that the plate assumes a more inclined position with respect to the shaft. The means for tilting the plate can be operated independently of the means for operating the valves.
