Abstract

La présente invention se rapporte à un servo-frein. Le servo-frein de l'invention comporte un piston amplificateur 1 à l'intérieur duquel se trouve une soupape 2 reliée à la pédale de frein 3. Le piston 1 est relié aux pistons 10 et 11 du maître-cylindre par un piston intermédiaire 9. Un piston à gradins 15 disposé en parallèle est situé entre une chambre 14 délimitée par les pistons 1 et 9 et la chambre 6 d'amplification. L'invention s'applique dans le domaine de l'automobile.
