Abstract

Dispositif d'actionnement à fluide 20 ayant une chambre à fluide de forme allongée 24 qui comporte une paroi 26 reliant une première et une seconde extrémités longitudinalement opposées 27, 28 et un piston 22 placé dans la chambre, espacé latéralement de la paroi de la chambre et mobile longitudinalement entre une première et une seconde position dans la chambre. Deux membranes 40, 42 sont placées entre le piston et la paroi de la chambre, chaque membrane comportant une partie souple formant un saillant longitudinal 68 entre le piston et la paroi de la chambre, ce qui fait que le déplacement du piston entre sa première et sa seconde position s'accompagne d'un roulement de la partie souple saillante de chaque membrane. Application à commande du débit des fluides inflammables.
