Abstract

Dispositif d'actionnement comprenant un tube 10 fermé à ses extrémités par deux éléments 11, 12 dont un est traversé par un piston 15, de manière à former un cylindre qui est empli d'un fluide (cire ou alcool). bords périphériques du tube 21, 22 sont refoulés vers l'intérieur pour maintenir les éléments de fermeture 11, 12, qui sont poussés vers l'extérieur par le fluide. Application aux actuateurs thermosensibles.
