Abstract

L'invention concerne un dispositif de commande par fluide. Ce dispositif comporte au moins trois unités de commande destinées chacune à déplacer une pièce mobile entre deux positions de travail et une position de repos. Chaque unité de commande comporte un corps cylindrique avec une cavité dans laquelle peuvent se déplacer deux pistons définissant trois chambres dans lesquelles est introduit sélectivement un fluide sous pression, dans différentes combinaisons. L'invention s'applique notamment à la commande d'une boîte de vitesses de véhicule automobile.
