Abstract

L'invention concerne un multiplicateur de dépression comprenant un corps principal, une plaque de piston recevant une force de pression différentielle produite entre deux chambres définies dans le corps principal, un corps de vanne cylindrique où est incorporé un moyen formant vanne pour connecter ou intercepter la communication entre les deux chambres et entre l'une des chambres et l'atmosphère, et une connexion du type à baïonnette entre la plaque de piston et le corps de vanne. Selon l'invention un organe de contrôle de rotation 10 est attaché à la plaque de piston 3, et une partie 10b de l'organe 10 peut engager le corps de vanne pour restreindre sa rotation relative par rapport à la plaque de piston 3 et empêcher la déconnexion de la connexion du type à baïonnette. L'invention s'applique notamment aux systèmes de freinage hydraulique de vehicules.
