Abstract

Dispositif de soupapes de commande pour système de freinage hydraulique double de véhicule, dans lequel deux soupapes de freinage 5, 6 sont actionnées indépendamment ou simultanément pour freiner les deux côtés du véhicule. Une soupape 21 alimente une chambre 14 en liquide fourni par une pompe à une entrée 17 à travers un clapet de non-retour 20, et ce liquide est comprimé dans la chambre 14 par un piston 26 lorsque la soupape 21 est ouverte. Le liquide s'échappe de la chambre 14 par une soupapge 29, 26 qui se ferme avant que la première soupape 21 ne puisse s'ouvrir. Application aux véhicules et notamment aux tracteurs agricoles.
