Abstract

Générateur de pression à fluide, notamment du type maître cylindre comportant une valve de proportionnalité permettant de réaliser un équilibrage de la pression de freinage entre les freins avant et les freins arrière. Le dispositif selon l'invention comporte deux chambres de pression respectivement primaire 22 et secondaire 24 et deux pistons permettant de mettre le fluide sous pression dans ces deux chambres et le second piston 20 est creux et renferme un système formant valve 62 comportant un élément de vanne 52 et un élément de commande 80 susceptible, en fonction de la pression de freinage, d'entraver de façon variable et proportionnelle la transmission de fluide entre la chambre secondaire 24 et la sortie 76 reliée au circuit hydraulique du système de freinage des freins arrière. L'invention s'applique notamment au domaine de l'automobile.
