Abstract

Micro-soupapes intégrées à commande électrique conçues pour réguler l'écoulement et la pression d'un fluide. Ces soupapes convertissent l'énergie électrique en énergie mécanique par un dispositif de conversion d'énergie (120) présentant une cavité étanche (100) avec une paroi flexible (200). Cette cavité étanche (100) contient un fluide (130) qui se dilate et se contracte lorsqu'il est chauffé ou refroidi, entraînant un mouvement de la paroi flexible (200). Le mouvement de cette paroi (200) ou membrane est utilisé pour mouvoir un élément soupape (300) et réguler de manière dynamique l'ouverture ou la fermeture de l'orifice (400) d'une soupape sur une distance prédéterminée.
