Title
(EN) ACTUATOR AND METHOD FOR IMPROVING AN ACTUATOR
(FR) ACTIONNEUR ET PROCÉDÉ D'AMÉLIORATION D'UN ACTIONNEUR
Abstract
(EN) The present invention is about an actuator comprising at least one shape-memory-alloy based converter in a housing and at least one preload spring. The actuator is configured to cause a motion of at least one movable member. The optimal structures along with corresponding methods for improving an actuator are claimed in the independent claims. Preferable embodiments are presented in the dependent claims.
(FR) La présente invention concerne un actionneur comprenant au moins un convertisseur à base d'alliage à mémoire de forme dans un boîtier et au moins un ressort de précharge. L'actionneur est configuré pour provoquer un mouvement d'au moins un élément mobile. Les structures optimales avec des procédés d'amélioration d'un actionneur correspondants sont revendiquées dans les revendications indépendantes. Les revendications dépendantes présentent des modes de réalisation préférables.
