La présente invention a pour but d'améliorer les machines et moteurs
énergétiques faisant l'objet du brevet canadien N o 1 229 749 émis le 1er
décembre 1987,
en remplaçant, par rapport à la machine connue par ce brevet, le piston et la
pale, par des
pistons-culbuteurs, chaque piston-culbuteur étant d'une part articulé par une
tige sur le
noyau de la machine, et d'autre part reliés entre eux au moyen d'une bielle,
de manière
à ce que chaque arrête du piston-culbuteur, lors de la rotation du noyau,
touche toujours
le cylindre de la machine, ce qui a pour effet d'annuler le frottement d'une
part, et de
réaliser une chambre à combustion dont la forme est plus favorable au couple
d'autre
part.
