Abstract

Abstract Translated from French L'invention concerne un circuit de freinage à amplification hydraulique de l'effort d'entrée, relié à une chambre de travail d'un maître-cylindre (1) commandé par une pédale de frein et comprenant une source de fluide sous haute pression (5), un moteur de frein (12), une première valve (10) pilotée établissant ou interrompant par l'intermédiaire d'un clapet anti-retour (17) une communication entre ladite source de fluide sous pression (5) et ledit moteur de frein (12) en fonction de la différence entre les pressions du fluide de ladite source et du fluide dans ladite chambre de travail du maître cylindre. Selon l'invention, il comprend en outre une deuxième valve (20) pilotée par la pression du fluide de ladite source (5) et comportant un clapet (24) interrompant normalement une communication entre ladite chambre de travail et ledit moteur de frein (12), et établissant cette communication en cas de défaillance de la source. Application aux véhicules automobiles. The invention relates to a brake circuit with hydraulic amplification of the input force, connected to a working chamber of a master cylinder (1) controlled by a brake pedal and comprising a source of fluid under high pressure ( 5), a brake motor (12), a first piloted valve (10) establishing or interrupting by means of a non-return valve (17) a communication between said source of pressurized fluid (5) and said motor brake (12) as a function of the difference between the pressures of the fluid of said source and of the fluid in said working chamber of the master cylinder. According to the invention, it further comprises a second valve (20) controlled by the pressure of the fluid from said source (5) and comprising a valve (24) normally interrupting communication between said working chamber and said brake motor (12). ), and establishing this communication in the event of source failure. Application to motor vehicles.
