Abstract

Soupape de réduction de pression sensible à la charge pour un dispositif de freinage hydraulique d'un véhicule. La soupape selon la présente invention comprend : une soupape de répartition de pression de fluide 100 qui réduit l'alimentation de fluide entre un maître-cylindre 21 et des cylindres de freins de roues 102; un clapet sphérique de détection de décélération 310 commandé par inertie qui, sous l'effet d'une décélération prédéterminée du véhicule, se déplace sur une rampe inclinée 304 et ferme l'alimentation d'une chambre de commande 33 qui commande la soupape de répartition 130, fixant ainsi la pression de départ de l'action de réduction de pression; un moyen de commande de la décélération qui doit être détectée commandé par la pression du fluide hydraulique provenant du maître-cylindre et ayant pour effet d'augmenter l'angle d'inclinaison de la rampe inclinée pour faire varier distribution de l'effort de freinage sur les roues avant et arrière du véhicule. Application à une soupape de réduction-répartition de pression de freinage qui permet de rendre optimale la distribution de la pression de freinage sur les roues avant et arrière d'un véhicule quelles que soient les conditions de charge du véhicule.
