Patent DE-2649363-A1 (DE)
Title: Closed cycle heat to mechanical energy converter - uses superheated vapour circulating in variable volume chamber to heat injected vapour
Inventor: VEDDER KARL FRIEDRICH
IPC: F01K25/04
Filed: 1976-10-29
Abstract: The closed cycle thermal to mechanical energy converter has a basically conventional cylinder and reciprocating piston arrangement. However above the piston crown there is a cylindrical sleeve of insulating material, sealing against the cylinder at the top. A spigot housing a high temp., high intensity heat sorce projects into this sleeve. This superheats vapour which, due to thermal gradients, circulates around a ring supported from the cylinder head. Relatively cold vapour is mixed with the circulating mass via the space between sleeve and spigot, causing net expansion. This vapour is injected through cylinder wall nozzles to flow first down the sleeve, absorbing low temp. heat from outside. Exhaust ports release surplus gas.
