Abstract

L'invention concerne un appareil destiné à faire varier le degré de freinage du système de freinage d'un véhicule en fonction de la charge Ledit appareil comporte un régulateur destiné à ajuster le rapport dune pression de sortie à une pression d'entrée en fonction d'un signal appliqué qui dépend de la charge, et une valve de << tarage >> capable d'établir une plage initiale de pressions de sortie qui est indépendante du signal dépendant de la charge jusqu'à une valeur prédéterminée, et un dispositif à action progressive fonctionnant après que ladite valeur prédéterminée a été atteinte pour supprimer la composante de pression indépendante de la charge en cas d'accroissement de la pression de sortie. Application à un système de freinage de véhicules dont l'action varie en fonction du chargement de ces derniers.
