Abstract

Invention concernant le freinage des véhicules. Surpresseur pour appliquer un frein hydraulique, qui comprend un piston de travail se déplaçant, pour actionner un piston de maître-cylindre, dans un alésage ménagé dans un boîtier, pourvu d'une chambre de pression qui soumet ce piston à une pression hydraulique. Le surpresseur incorpore une valve de commande de surpression, sensible à la pression d'une chambre de commande, réglée par une pédale grâce à un piston d'entrée; cette chambre est délimitée entre le piston d'entrée et un deuxième piston et une valve de récupération règle sa communication avec un réservoir à fluide. Application à la réalisation de freins hydrauliques moins sensibles aux défectuosités des joints.
