Abstract

L'invention concerne un dispositif de rappel élastique. Elle se rapporte à une combinaison d'un embrayage de sécurité et de butées telle que l'embrayage est fixé au boîtier afin qu'un ressort puisse exercer une force sur l'arbre d'un dispositif de mise en action mais, avant démontage du dispositif de mise en action, la plaque d'embrayage est libérée et dissipe l'énergie conservée par le ressort. Application aux dispositifs de rappel des vannes à commande automatique.
