Abstract

Servo-moteur fonctionnant au moyen d'une matière expansible sous l'effet de la chaleur et comprenant un dispositif de commutation de position terminale à ressorts 25. Au moins un ressort 33, 41 de ce dispositif de commutation 25 est aménagé sur le passage de la transmission de la force entre la partie fixe du moteur 8 et un support fixe 32. Application : réglage d'un clapet d'étranglement dans une conduite d'air.
