Abstract

L'invention concerne une vanne (2) pour le guidage de fluide, notamment pour le dosage d'un fluide, à travers une ouverture de guidage (12), la vanne étant conçue de façon bistable entre deux états d'ouverture de l'ouverture de guidage. La vanne comporte une armature mobile (10) pour ouvrir et fermer l'ouverture de guidage, laquelle comprend un matériau magnétique ainsi qu'un élément (17) pour générer un champ magnétique et pour mouvoir l'armature. Pour pouvoir obtenir un actionnement amélioré, le dispositif comprenant du matériau magnétique présente deux aimants permanents (13, 14) qui sont disposés avec des pôles de même nom dirigés l'un vers l'autre et sont appliqués de telle manière qu'ils se trouvent à une distance fixe l'un par rapport à l'autre. L'invention concerne également un dispositif de dosage (1).
