Abstract
Mécanisme de rotation d'une soupape La soupape peut effectuer un mouvement de va-et-vient entre des positions ouverte et fermée le long d'un axe longitudinal autour duquel elle peut tourner. Le mécanisme comprend des premier et second élements mobiles axialement et tournant l'un par rapport à l'autre le long et autour dudit axe longitudinal. Plusieurs billes mobiles disposées entre les éléments peuvent se déplacer le long de trajets prédéterminés et imprimer un mouvement relatif de rotation aux éléments pendant qu'ils se déplacent axialement. Chaque bille se déplace dans un alvéole le long d'une rampe qui est constituée par plusieurs surfaces inclinées d'angles différents par rapport à un plan perpendiculaire à l'axe longitudinal de la soupape. Application aux soupapes commandées par des culbuteurs d'un moteur à combustion interne.
