Abstract

La présente invention concerne une servocommande (20). La servocommande (20) comporte au moins un corps (25) ainsi qu'une tige de puissance (30) et un piston de commande (35) agencé dans chaque corps (25), ledit au moins un corps (25) et ladite tige de puissance (30) formant respectivement deux organes de puissance (200). Un desdits organes de puissance porte au moins un organe de butée (40) et l'organe de puissance dépourvu de l'organe de butée (40) porte un actionneur de passivation (50). L'actionneur de passivation (50) comprend une tige de passivation (56) qui porte une butée (57) et un piston de passivation (55), ledit piston de passivation (55) étant agencé mobile en translation longitudinale dans une enceinte (52), un système élastique (60) étant agencé entre ledit piston de passivation (55) et ladite enceinte (52).
