Abstract

L'invention concerne deux moteurs à combustion interne, ainsi que les compresseurs ou les pompes qui en sont dérivés et qui fonctionnent selon le principe de la rotation. Les deux moteurs se caractérisent par une structure très simple et compacte, et comprennent essentiellement un carter cylindrique dans lequel se trouvent deux pistons rotatifs imbriqués l'un dans l'autre, à symétrie d'axe. Les pistons rotatifs effectuent un mouvement oscillant dans un premier moteur et un mouvement rotatif alternatif dans un sens, dans le second moteur. Dans les deux moteurs, la transmission de force motrice s'effectue par l'intermédiaire d'un levier, d'une bielle et d'une manivelle, dans un sens de rotation. Le vilebrequin du second moteur tourne, en outre, autour de l'axe du cylindre, à la manière du satellite d'un engrenage planétaire.
