L'invention concerne un moteur thermique doté d'un piston double effet, destiné à faire travailler la bielle (113) à la compression sous l'effet d'une explosion dans la chambre de travail supérieur (173) et à l'extension sous l'effet d'une force résultant d'une restitution d'énergie dans la chambre de travail inférieur (157), ces deux forces agissent sur chaque bielle et par tour. L'air comprimé dans la chambre de compres sion (156) est surchauffé lors de son passage dans l'échangeur de chaleur (105) avant d'agir sur le piston de compression récupération (109) qui est destiné à transformer l'énergie thermique en énergie mécanique par effet thermodynamique. Le moteur selon l'invention est destiné aux mêmes utilisations que les moteurs thermiques actuels.A thermal engine with thermal energy recovery, equipped with a multifunction piston with double effect, to obtain two working forces per revolution on a single connecting rod. The invention relates to a heat engine having a double-acting piston for operating the connecting rod (113) to compression under the effect of an explosion in the upper working chamber (173) and the extension under the effect of a force resulting from a return of energy in the lower working chamber (157), these two forces act on each rod and by turn. The compressed air in the compression chamber (156) is superheated as it passes through the heat exchanger (105) before acting on the recovery compression piston (109) which is intended to transform the thermal energy in mechanical energy by thermodynamic effect. The engine according to the invention is intended for the same uses as current thermal engines.
