Abstract

L'INVENTION CONCERNE UNE SOUPAPE DE COMMANDE DE PRESSION HYDRAULIQUE DANS UN CIRCUIT DOUBLE DE FREINAGE POUR UN VEHICULE AUTOMOBILE. LA SOUPAPE DE COMMANDE DE PRESSION 10 COMPREND DEUX SOUPAPES DE PROPORTIONNALITE 26, 28 AGENCEES PARALLELEMENT, ET UNE SOUPAPE 66 DE DETECTION DE DECELERATION QUI REGLE L'AMPLITUDE DE LA CHARGE APPLIQUEE A UN RESSORT 60 COMMUN AUX DEUX SOUPAPES DE PROPORTIONNALITE, EN FONCTION DU DEGRE DE DECELERATION DU VEHICULE. L'INVENTION PERMET D'EVITER LE BLOCAGE DES ROUES ARRIERE AU FREINAGE DU VEHICULE.
