Abstract

Mécanisme de rotation d'une soupape autour de son axe longitudinal pendant qu'elle effectue un mouvement de va-et-vient entre des positions ouverte et fermée. Il comprend des premier et second éléments mobiles axialement et rotatifs l'un par rapport à l'autre le long et autour dudit axe longitudinal Une rondelle Belleville disposée entre les éléments comprend dans sa partie centrale un creux dont la surface concave porte contre la périphérie d'éléments mobiles tels que des billes ou les spires d'un ressort annulaire qui, en coopération avec la rondelle, font tourner les éléments l'un par rapport à l'autre et donc la soupape par rapport à son siège, lorsque lesdits éléments se déplacent axialement l'un par rapport à l'autre. Application au mécanisme faisant tourner une soupape d'un moteur à combustion interne.
