Abstract

Invention concernant le freinage des véhicules. Dans un surpresseur à pression pneumatique, l'excitation d'une chambre de travail est réglée par un mécanisme de soupape 13 pouvant être actionne par un organe d'entrée à pédale 8 qui est disposé pour agir sur un organe de sortie 10 en cas de manque de fonctionnement du surpresseur. Une force développée par l'excitation de la chambre de travail est appliquée à l'organe de sortie 10 par l'intermédiaire d'une liaison hydraulique 25. Application à la réalisation de surpresseurs pneumatiques pour freins hydrauliques, dans lesquels un pot constituant la chambre de travail peut être monté en tout endroit convenable, ce qui facilite l'installation dans un espace limité
