Abstract

L'invention concerne un dispositif de commande de pression pour systèmes de freinage hydraulique. Ce dispositif comprend essentiellement un piston principal 2 séparant une chambre d'entrée 8 et une chambre de sortie 9 et formant soupape par son bord 5 avec un élément de soupape 4. Un piston auxiliaire 16 peut agir sur le piston principal par l'intermédiaire d'un poussoir 20 lorsqu'une pression auxiliaire est appliquée à une chambre de commande 18. Une force de commande 12 est appliquée au piston 2. Le dispositif fonctionne en distributeur de force de freinage ou comme élément d'un système antiblocage selon que la pression auxiliaire n'est pas appliquée ou l'est L'invention s'applique aux systèmes de freinage de véhicules automobiles.
