Abstract

Valve à deux positions actionnée par dépression, commutable d'une position de repos à une position de travail lorsqu'elle est connectée à une source de dépression, la commutation étant retardée de quelques secondes après connection à la source de dépression. Lorsque le niveau de dépression croît, la valve est rappelée vers sa position de repos pendant quelques secondes puis déplacée à nouveau vers la position de travail. Un piston de commande est relié à la valve et rappelé élastiquement vers la position de repos. Un piston auxiliaire est déplacé en direction du piston de commande lors de la mise sous dépression. Des orifices à passage restreint empêchent le déplacement du piston de commande tant que les pressions de part et d'autre de ce dernier ne sont pas égalisées. Application aux systèmes de contrôle anti-pollution pour moteurs à combustion interne.
