Abstract

L'INVENTION CONCERNE UNE UNITE DE COMMANDE DE PRESSION DE FREINAGE POUR UN SYSTEME DE FREINAGE HYDRAULIQUE A DEUX CIRCUITS. CETTE UNITE COMPREND DANS UN BOITIER 1 DEUX ALESAGES 2, 3 CONTENANT RESPECTIVEMENT UN PISTON DE COMMANDE 5 ET UN PISTON ETAGE 29 QUI COMPORTENT DES SOUPAPES 21, 22, 23; 35, 36 ASSOCIEES RESPECTIVEMENT AUX DEUX CIRCUITS DE FREINAGE HZI, RZI; HZII, RZII. LA SOUPAPE DU PISTON 5 EST COMMANDEE PAR LA DIFFERENCE DE PRESSION ENTRE L'ENTREE ET LA SORTIE DE L'AUTRE SOUPAPE 35, 36. CELLE-CI PEUT ETRE UNE SOUPAPE SENSIBLE A LA DECELERATION. L'INVENTION S'APPLIQUE AUX SYSTEMES DE FREINAGE A DEUX CIRCUITS POUR VEHICULES AUTOMOBILES.THE INVENTION RELATES TO A BRAKE PRESSURE CONTROL UNIT FOR A TWO-CIRCUIT HYDRAULIC BRAKING SYSTEM. THIS UNIT INCLUDES IN A BOX 1 TWO BORES 2, 3 CONTAINING RESPECTIVELY A CONTROL PISTON 5 AND A STAGE PISTON 29 WHICH INCLUDE VALVES 21, 22, 23; 35, 36 RESPECTIVELY ASSOCIATED WITH THE TWO BRAKING CIRCUITS HZI, RZI; HZII, RZII. THE PISTON VALVE 5 IS CONTROLLED BY THE PRESSURE DIFFERENCE BETWEEN THE INLET AND OUTLET OF THE OTHER VALVE 35, 36. THIS MAY BE A VALVE SENSITIVE TO DECELERATION. THE INVENTION APPLIES TO TWO-CIRCUIT BRAKING SYSTEMS FOR MOTOR VEHICLES.
