Abstract

L'invention concerne un actionneur avec un élément élastomère (3) magnétorhéologique, qui, en utilisant l'effet de mémoire de forme, peut prendre plusieurs formes sous l'influence d'une force magnétique et agir directement ou indirectement sur un courant de fluide, de telle sorte que sa surface en section transversale varie en fonction du changement de forme de l'élément élastomère. De préférence, l'élément élastomère magnétorhéologique agit sur un élément tubulaire (1) déformable élastiquement, dont la surface libre en section transversale peut varier en fonction d'un changement de forme de l'élément élastomère, afin de faire varier un courant de fluide guidé dans l'élément tubulaire. En l'occurrence, l'élément élastomère magnétorhéologique peut entourer le courant de fluide ou l'élément tubulaire qui le conduit, de manière essentiellement annulaire, tandis que l'élément élastomère magnétorhéologique est supporté au moins avec son côté opposé à l'élément tubulaire ou au courant de fluide, sur un élément de support (2) sensiblement non déformable par l'élément élastomère magnétorhéologique.
