Abstract
L'invention a trait à un dispositif de commande pour appareils actionnés par pression de fluide Elle a pour objet un dispositif du type décrit dans le brevet principal et comportant, en plus un orifice de détection de charge pour une liaison à un organe actionnable pour modifier la pression de fluide sur l'orifice d'admission. L'agencement de valve à tiroir étant réalisé de manière à éviter une fuite interne en réduisant la longueur de l'interface entre fluide mesuré et de retour et entre fluide mesuré et non mesuré. Application : direction assistée de véhicules.
