Abstract
Invention concernant surtout le freinage des véhicules. Système hydraulique dans lequel un accumulateur hydraulique est chargé en fluide hydraulique sous pression au moyen d'une pompe qui soutire le fluide d'un réservoir ; une valve agit pour empêcher la surcharge de l'accumulateur et permettre sa recharge Ladite valve incorpore une valve de commande et un élément piston asservi, actionné par le fluide, coopérant avec des ressorts. Application à la réalisation de tels systèmes hydrauliques.
