Abstract

MAITRE CYLINDRE DOUBLE POUR CIRCUIT DE FREINAGE. LES PRESSIONS DANS LES DEUX CHAMBRES DU MAITRE-CYLINDRE DIFFERENT TOUJOURS D'UNE FAIBLE VALEUR, CE QUI ENGENDRE UNE USURE DIFFERENTIELLE DES ELEMENTS DE FRICTION DES FREINS, PRINCIPALEMENT DANS LES CIRCUITS EN X. A LA SORTIE DE CELLE DES CHAMBRES OU LA PRESSION CROIT LE PLUS RAPIDEMENT, ON A PREVU UNE SOUPAPE DE RETENUE TAREE, DE SORTE QUE LES PRESSIONS REGNANT DANS LES DEUX CIRCUITS DE FREINS SONT RENDUES PRATIQUEMENT EGALES. APPLICATION AUX SYSTEMES DE FREINAGE POUR VEHICULES AUTOMOBILES.
