Abstract

La présente invention concerne un dispositif de commande destine à un système sensible à la vitesse pour un véhicule à moteur. Le dispositif selon l'invention comprend une première chambre D limitée en partie par une cloison mobile 23b et communiquant avec deux autres chambres A1 et A2, associées chacune à une valve de contrôle électromagnétique B, C. La valve C est alimentée en tension continue et controle un orifice 10 mettant en communication ladite première chambre et l'atmosphère. La valve B est alimentée à la fois en tension continue et en tension pulsée et est conçue pour contrôler à la fois un orifice 17 reliant ladite première chambre à l'atmosphère et un orifice 16 reliant ladite première chambre à une source de gaz dont la pression est inférieure à la pression atmosphérique. Application au contrôle de la soupape de réglage ou analogue d'un moteur de véhicule.
