Abstract

Moteur à explosion à piston entraîné par une came, comprenant un cylindre, un piston, un mécanisme d'admission et d'échappement, un système d'allumage, un axe de transmission monté dans ledit piston, et une came cylindrique. Le moteur transforme le mouvement horizontal du piston en rotation de l'arbre grâce à la coopération entre ledit axe de transmission et ladite came cylindrique, le remplacement du mécanisme classique de transmission par vilebrequin et bielle étant ainsi possible. Ce moteur a une structure peu encombrante faiblement dimensionnée et légère, et il fonctionne avec fiabilité et sans à-coups.
