Abstract

Invention concernant le freinage des véhicules. Surpresseur, actionné par pédale, incluant un mécanisme de soupape pour commander la d'une chambre 52 et comprenant un piston 5 actionné par la pédale et un cylindre de soupape 19 qui lui est accouplé avec un mouvement relatif limité, dans une chambre de travail 54 que comporte le piston 5. Le cylindre 19 isole la chambre 52 de l'orifice d'évacuation 38 et met un orifice 12 d'alimentation d'une pression extérieure en communication avec la chambre de travail 54. Application à la réalisation d'un frein hydraulique à course de pédale convenable.
