Abstract

L'invention porte sur un régulateur de fluide qui comprend un élément de commande (20) disposé dans un corps de soupape (12) et qui peut se déplacer par rapport à l'orifice de soupape (18) pour commander l'écoulement. Une tige coulissante (22) attaque l'élément de commande et déplace l'élément de commande, la tige comprenant une partie supérieure (24), une partie inférieure (26) et une partie intermédiaire (28). Le dispositif comprend en outre une cartouche à levier (40) disposée dans le corps de soupape, la cartouche à levier accouplant fonctionnellement un actionneur (38) à la tige, et il comprend des premier et second leviers pivotants dont chacun présente des première et seconde extrémités et des parties intermédiaires, la partie intermédiaire du premier levier attaquant la tige. Le premier levier (42) attaque la partie intermédiaire (56) du second levier (44), et le second levier est accouplé fonctionnellement à une partie de l'actionneur, de telle sorte que les premier et second leviers et la tige répondent au mouvement de l'actionneur en déplaçant l'élément de commande entre les positions ouverte et fermée.
