Abstract

A. Installation qui comprend une source de pression de fluide et un servo-ensemble, comprenant un carter de soupape ayant un orifice d'entrée de pression de fluide communiquant avec la source, un orifice de sortie de fluide à haute pression communiquant avec des organes de freinage, un orifice de sortie de fluide à basse pression communiquant avec un réservoir de fluide B. Installation caractérisée par un piston de travail coulissant dans un cylindre dans le carter déplaçable dans un sens de direction axiale pour comprimer une chambre de travail formée entre le piston et le cylindre, cette chambre étant en communication constante avec l'orifice de sortie de fluide à haute pression, un déplacement manuel du piston dans la direction en question, causant une réaction sur le piston par la pression de fluide dans la chambre qui oppose une résistance au déplacement, cette résistance étant indicatrice de la pression de fluide appliquée dans les organes de freinage. C. Installation applicable à des véhicules automobiles.
