Abstract

Amplificateur de freinage comportant un ensemble de valves pour contrôler la communication entre une source de haute pression, un accumulateur de pression et la chambre de pression de l'amplificateur. L'ensemble de valves est monté dans un alésage qui débouche dans la chambre de pression, et comporte une valve de retenue ayant un manchon en matériau rigide et une garniture déformable montée dans le manchon. Un passage est prévu dans la garniture pour contrôler la communication de fluide vers la chambre de pression. L'ensemble de valves comporte également une valve de charge mobile dans l'alésage et qui contrôle la communication de fluide entre l'orifice d'entrée et l'accumulateur. L'élément d'obturation est mobile dans l'alésage et est susceptible de venir en butée contre le manchon.
