Abstract

L'invention concerne un moteur orbital radial rotatif qui peut fonctionner de nombreuses manières différentes : par l'apport de carburant, d'essence, d'alcool ou de biocarburant; par la vapeur, l'air, l'électricité et/ou toute sorte de liquide. Ce moteur est composé essentiellement d'un nombre variable de pistons (5), d'un axe de moteur (7), d'une soupape centrale (9) et d'ensembles de différentes cames (2), lubrifié et refroidi à l'huile. L'ensemble de chemises (4) dudit moteur est fixe ou couplé à l'axe de moteur; l'ensemble tourne conjointement avec l'axe de moteur; les pistons effectuent leur mouvement alternatif - ou un déplacement volumétrique - dans la chemise grâce à ses axes munis de rouleaux ou de paliers qui entrent contact avec les chemins de came, éliminant ainsi les bielles d'accouplement et les manivelles dans l'axe de moteur.
