Procedure and devices relating to a cyclical internal combustion engine with a constant-volume independent combustion chamber in which, for each working cylinder or element, combustion chamber (1), combustion chamber (2) and expansion chamber (4) are made up of three separate, entirely independent parts. The cycle of the compression chamber is advanced in relation to that of the expansion chamber, in order to allow for lengthy combustion periods. The compressed carbonized mixture is introduced into combustion chamber (2) once its flap (6) has opened, shutting off a conduit (5) between the compression chamber and the expansion chamber; once flap (6) is closed, combustion takes place in the constant-volume independent chamber, which is isolated for an extended period. When the volume of expansion chamber (4) is at its lowest level, flap (8) is opened, shutting off conduit (7) between the combustion chamber and the expansion chamber, and the gases burned under high pressure expand, pushing back piston (15) and creating the working cycle. All engine applications are concerned.

Procédé et dispositifs de moteur, à combustion interne cyclique, à chambre de combustion indépendante à volume constant dans lequel, pour chaque cylindre ou élément de travail, la chambre de compression (1), la chambre de combustion (2), et la chambre de détente (4) sont constituées de trois parties séparées et entièrement indépendantes. Le cycle de la chambre de compression est décalé en avance par rapport à celui de la chambre de détente afin de permettre des temps de combustion importants. Le mélange carburé comprimé est introduit dans la chambre de combustion (2) dès l'ouverture d'un volet (6) obturant un conduit (5) ménagé entre la chambre de compression et la chambre de détente; dès la fermeture de ce volet (6), la combustion s'effectue dans la chambre indépendante à volume constant et isolée durant une longue période. Lorsque le volume de la chambre de détente (4) est à sa plus petite valeur, on ouvre un volet (8) obturant un conduit (7) ménagé entre la chambre de combustion et la chambre de détente, et les gaz brûlés sous haute pression se détendent en repoussant le piston (15) pour assurer le temps moteur. Toutes applications de moteur.
