Abstract

L'INVENTION CONCERNE UN DISPOSITIF DE FREINAGE A AMPLIFICATEUR HYDRAULIQUE. CE DISPOSITIF COMPREND UN PISTON DE TRAVAIL 2, UN PISTON DE TRANSMISSION 3 ET UN PISTON DE COMMANDE 5. DANS LE PISTON DE TRANSMISSION EST PREVU UN TIROIR 21 FORMANT UNE SOUPAPE D'ADMISSION 25, 26 ET UNE SOUPAPE DE DECHARGE 28, 29. UNE LIAISON 31, 32, 33 RELIE LA CHAMBRE D'ACTIONNEMENT 12 A LA CHAMBRE DE TRANSMISSION 11. UN FAIBLE DEPLACEMENT INITIAL DE LA PEDALE 6 PERMET D'ACTIONNER LE PISTON DE TRAVAIL 2 JUSQU'A CE QUE TOUTES LES COURSES A VIDE SOIENT RATTRAPEES SANS QUE LA PEDALE ET LE PISTON DE TRANSMISSION SOIENT OBLIGES DE SE DEPLACER DAVANTAGE. L'INVENTION S'APPLIQUE AUX DISPOSITIFS DE FREINAGE POUR VEHICULES AUTOMOBILES.
