Abstract

L'INVENTION CONCERNE UN AMPLIFICATEUR DE FREINAGE HYDRAULIQUE. CET AMPLIFICATEUR COMPREND UN PISTON AMPLIFICATEUR 4, UN PISTON ANNULAIRE 7 S'APPUYANT SUR LE PISTON AMPLIFICATEUR ET UN PISTON CENTRAL 8 PROLONGE PAR UN TIROIR DE COMMANDE 18 QUI PEUT METTRE LA CHAMBRE 17 EN COMMUNICATION AVEC UN RESERVOIR NON SOUMIS A LA PRESSION OU AVEC UN ACCUMULATEUR DE PRESSION 3. LE PISTON CENTRAL 8 PORTE DEUX COLLETS ESPACES 11, 12 POUR COOPERER AVEC LE PISTON ANNULAIRE EN PERMETTANT UN CERTAIN MOUVEMENT RELATIF. LE PISTON CENTRAL ET LE PISTON ANNULAIRE SONT ACCOUPLES PAR LE COLLET 12 ET SE DEPLACENT EN BLOC LORSQUE LA FORCE DU RESSORT 15 A ETE SURMONTEE. L'INVENTION S'APPLIQUE AUX AMPLIFICATEURS DE FREINAGE HYDRAULIQUES POUR VEHICULES.
