Abstract

Deux ensembles, constitués d'un premier disque rotatif et d'un premier support de disque ainsi que d'un second disque rotatif et d'un second support, chaque disque ayant une face profilée concave/convexe, sont disposés coaxialement à un arbre rotatif dans un boîtier dans lequel les faces concaves/convexes sont placées à l'opposée. Le premier disque rotatif fait partie intégrante de l'arbre rotatif et le premier support, qui ne peut se mettre en rotation relativement à l'arbre rotatif, peut se déplacer axialement. Le second disque rotatif peut entrer en rotation avec l'arbre rotatif alors que le second support, qui ne peut entrer en rotation relativement à l'arbre rotatif, peut être déplacé axialement. Lorsque l'arbre rotatif entre en rotation, deux enceintes à volume variable sont formées, alternativement, entre les faces concaves/convexes dans les deux ensembles. La première enceinte possède un orifice d'admission de carburant et la seconde un orifice d'échappement. Entre les deux enceintes se trouvent un passage de communication de compression ainsi qu'une chambre de combustion de gaz communiquant l'un avec l'autre.
