Abstract

Le modulateur comporte une soupape entre un orifice d'entrée et un orifice de sortie. La position de la soupape est contrôlée par un dispositif pneumatique comportant une chambre séparée en deux cavités par un organe mobile sensible à la différence de pression entre les deux cavités. L'organe mobile commande le déplacement d'un plongeur dans une chambre de modulation relié aux moteurs de freins pour faire varier le volume disponible dans la chambre de modulation, et pour actionner la soupape En position de repos la soupape est ouverte et les deux cavités sont en communication entre elles par l'intermédiaire d'un passage défini dans l'organe mobile, d'une enceinte intermédiaire et d'un passage défini dans le boîtier et sont également en communication avec une source de vide. Lorsqu'un risque de patinage existe, la communication entre les deux cavités est interrompue et l'une d'entre elles est soumise à la pression atmosphérique pour déplacer l'organe mobile et le plongeur de manière à fermer la soupape et augmenter le volume effectif de la chambre de modulation.
