Abstract

Arbre composé formé d'un arbre intérieur entouré concentriquement par un arbre creux, les deux arbres supportant des cames et une roue de commande est équipée d'un mécanisme destiné à provoquer les variations des positions angulaires relatives en fonction d'un paramètre de la commande, par exemple de la vitesse. Ce mécanisme comprend un support de came 33 qui est tanslatable radialement en fonction du paramètre le long d'un guide radial 31 que comporte la roue de commande 3, ce support formant l'assise d'une came de réglage 39 contre laquelle est appliqué un levier palpeur 36 solidarisé en rotation avec l'un des deux arbres 1 et 2. Application aux moteurs des voitures pour permettre la variation du recoupement de l'ouverture des soupapes d'échappement et d'admission en fonction de la vitesse.
