Abstract

L'invention concerne un amplificateur de freinage hydraulique. Cet amplificateur 1 commande un maître-cylindre 3 par l'intermédiare d'un poussoir 16 coaxial avec une soupape de réglage 2. Les entrées 24 et 26 sont reliées à une pompe 4 refoulant le fluide de pression prélevé dans un réservoir 6. L'amplificateur 1 comprend un tiroir de distribution 15 dans un piston amplificateur 13 et assure la liaison d'une chambre 14 soit avec la pompe 4 soit avec le réservoir 6. Le courant de fluide de la pompe peut être étranglé par une soupape 19, 31, 20. L'invention s'applique aux freins de véhicules automobiles.
