Abstract

L'invention concerne un actionneur piézo-électrique à déconnexion automatique en cas de panne de courant. L'actionneur, conçu comme un piston (11) de pression axiale, est axialement supporté par un support de pression (15) qui est conçu sous forme de levier à genouillère (15) pliable. En mode marche, ce support de pression (15) est maintenu en position d'extension par un électroaimant (14).
