Abstract

Système de commande hydraulique de deux cylindres actionneurs dont les pistons présentent chacun deux surfaces de pression opposées d'aires différentes, comportant, par cylindre, une soupape de commande à deux passages, manoeuvrée par un volant de direction, et un dispositif de mesure à deux passages à débit constant pour alimenter respectivement les deux cylindres. Les aires des surfaces de pression F1, F2 de chaque piston 18a, 18b sont dans le rapport 2/1, la grande surface F1 d'un des pistons étant toujours mise sous pression en même temps que la petite surface F2 de l'autre 18a dont les deux surfaces sont mises sous la même pression. Application : commande hydraulique de direction.
