Abstract

L'INVENTION CONCERNE UN APPAREIL DE COMMANDE A POSITIONS MULTIPLES, ACTIONNE PAR UN FLUIDE SOUS PRESSION. CET APPAREIL COMPREND UN CYLINDRE DANS LEQUEL PLUSIEURS PISTONS PEUVENT SE DEPLACER PAS A PAS, SUR DES DISTANCES PREDETERMINEES, SOUS L'EFFET DE PRESSIONS PREDETERMINEES. CES PISTONS COMMANDENT UN ELEMENT DE SORTIE POUVANT ACTIONNER, PAR EXEMPLE, UN ACCELERATEUR DE MOTEUR. DOMAINE D'APPLICATION: COMMANDE DE L'ACCELERATION ET DE LA VITESSE DES MOTEURS THERMIQUES DE TRACTION DE VEHICULES FERROVIAIRES.
