Abstract
Un tel robinet comprend deux soupapes 8, 19 disposées l'une derrière l'autre dans un corps de robinet 1, une tige d'actionnement 2 qui plonge dans le corps de robinet et y agit sur un piston 6 portant une partie (siège 7) de la première soupape 8, un dispositif pour actionner la deuxième soupape 19 et un dispositif de commande en fonction de la charge qui influe sur l'action de ce dispositif d'actionnement et est formé d'un piston étagé 17' présentant plusieurs gradins a, b, c, qui est disposé mobile dans un alésage étagé complémentaire, également plusieurs gradins aux transitions entre des portions de différents diamètres, et qui est susceptible d'être étanché efficacement à l'un de ses gradins suivant l'influence désirée de la charge du véhicule sur le travail de commutation du robinet
