Abstract

Soupape de réglage de débit à commande électrique. Selon l'invention, la soupape utilise un fluide-pilote qui commande la position d'un tiroir afin d'ajuster les dimensions d'un orifice de réglage, la pression de ce fluide pouvant être augmentée jusquà une valeur maximale, si nécessaire, pour déplacer ce tiroir. Un électro-aimant commande la régulation de la pression du fluide-pilote selon la position du tiroir. Grâce à ces dispositions, la pression de réglage peut être au besoin égale à la pression d'entrée dans la soupape, ce qui améliore la fiabilité et la sécurité de fonctionnement du dispositif, le tiroir pouvant être plus aisément débloqué en cas de coincement accidentel.
