Abstract

MAITRE-CYLINDRE A FONCTIONNEMENT SEQUENTIEL, DANS LEQUEL LE PISTON PRIMAIRE DEFINIT AVEC L'ALESAGE UNE CHAMBRE PRIMAIRE ET UNE CHAMBRE AUXILIAIRE ET PORTE UN ELEMENT DE VALVE SENSIBLE A LA PRESSION DE FLUIDE QUI S'ETABLIT DANS LESDITES CHAMBRES LORS D'UNE MANOEUVRE DE FREINAGE, CET ELEMENT DE VALVE CONTROLANT LA COMMUNICATION ENTRE LA CHAMBRE AUXILIAIRE ET SOIT LA CHAMBRE PRIMAIRE SOIT LE RESERVOIR. SELON L'INVENTION, L'ELEMENT DE VALVE 52 EST CONCU POUR DECHARGER PAR DOSES SUCCESSIVES LA CHAMBRE AUXILIAIRE 50 EN LA METTANT MOMENTANEMENT EN COMMUNICATION AVEC LE RESERVOIR 26 DES QUE LA PRESSION DANS LES CHAMBRES PRIMAIRE 38 ET AUXILIAIRE 50 ATTEINT UNE VALEUR PREDETERMINEE, CECI DE MANIERE A MENAGER UNE TRANSITION ENTRE LES DEUX MODES DE FONCTIONNEMENT DU MAITRE-CYLINDRE. APPLICATION AUX SYSTEMES DE FREINAGE POUR VEHICULES AUTOMOBILES.
