Abstract
INVENTION CONCERNANT LE FREINAGE DES VEHICULES. REGULATEUR DE LA PRESSION DE FREINAGE D'UN VEHICULE. IL COMPREND NOTAMMENT UN ENSEMBLE RENFORCATEUR 23 AVEC PISTON24 QUI COULISSE DANS UN ALESAGE25 COMMUNIQUANT AVEC LA SORTIE22 DESTINEE A ETRE RELIEE A UN FREIN DE ROUE ARRIERE. L'ENSEMBLE RENFORCATEUR 23 EST PLACE SOUS LA COMMANDE D'UNE SERVO-VALVE, ELLE-MEME SUBISSANT L'ACTION D'UNE PART D'UN ENSEMBLE A PISTON REPONDANT A LA PRESSION D'ENTREE, RELIEE A UNE SOURCE DE FLUIDE SOUS PRESSION ET D'AUTRE PART, L'ACTION OPPOSEE D'UN ENSEMBLE A DIAPHRAGME. UN PENDULE29, ACTIONNANT UNE VALVE30, SERT DE CAPTEUR DE DECELERATION ET ADMET DE L'AIR SUR LE DIAPHRAGME. AVEC UN TEL REGULATEUR LA PRESSION A LA SORTIE VARIE, RELATIVEMENT A LA PRESSION D'ENTREE, EN REPONSE A LA DECELERATION CAPTEE. APPLICATIONS DIVERSES, NOTAMMENT AUX TRACTEURS AVEC REMORQUE.
