Abstract

Actionneur à mécanisme de sécurité actionné par un ressort 33. Ce ressort est normalement maintenu inopérant par des moyens électriques 30, de sorte que le mécanisme de sécurité est indépendant du fonctionnement normal de l'actionneur. Le mécanisme de sécurité est rendu opérant par la disposition de l'alimentation électrique, de sorte que le ressort fait tourner une came discoïde 18 qui est accouplé à une came discoïde de sécurité 14 pour faire tourner l'arbre de sortie 13 jusqu'à une position predéterminée de sécurité sous l'action de l'énergie emmagasinée par la force élastique. Application : actionneur électrique, notamment pour vanne ou soupape quart-de-tour.
