Le moteur à explosion avec des pistons rotatifs a dans son boîtier plusieurs
cavités hébergeant
chacune un piston rotatif d'une forme spéciale. Des doubles-manivelles chacune
ayant la longueur
variable relient entre eux les pistons rotatifs deux par deux. Le couple
moteur cumulé de tous les
pistons rotatifs est transmis à l'arbre moteur par l'intermédiaire d'une
manivelle de longueur variable
dont il est relié.
Chaque piston rotatif tourne librement dans sa cavité en combinant le
mouvement de glissement avec
le mouvement de roulement ainsi que, comme résultat, à chaque rotation
complète du piston rotatif
l'arbre moteur exécute trois rotations complètes en sens inverse sans
l'utilisation de pignons ou
d'autres mécanismes. Ce moteur a un petit gabarit par rapport à d'autres
moteurs de même capacité,
un petit nombre de pièces en mouvement, un bon rendement de conversion de
l'énergie et un bon
équilibrage. Il offre la possibilité d'avoir beaucoup de ses pièces fabriquées
en matériaux céramiques
ou métal et céramiques.
