Abstract

Dispositif de manoeuvre à air comprimé comportant un cylindre il à l'intérieur duquel sont disposés deux pistons 10 coulissant en sens opposé, un élément d'entraînement 15 fixé à un arbre de sortie 16 et présentant un axe dirigé transversalement à l'axe de rotation dudit arbre et des moyens de transmission entre chacun des pistons et l'élément d'entraînement. L'agencement est tel que l'élément d'entraînement et l'arbre de sortie tournent d'un angle déterminé pendant le mouvement qu'effectuent les pistons entre leurs positions limites intérieure et extérieure, l'élément d'entraînement passant par une position intermédiaire dans laquelle son axe est perpendiculaire à la direction de mouvement des pistons, le deplacement angulaire de l'élément d'entraînement à partir de la position intermédiaire, lorsque les pistons se meuvent vers leur position limite extérieure, etant inférieur à son déplacement angulaire à partir de ladite position intermédiaire lorsque les pistons se meuvent vers leur position limite intérieure. Application, notamment, à la commande de valves.
