Abstract
Une vanne à commande électrique servant à réguler une pression de régime provenant d'une charge de volume fermé comporte d'une part une vanne d'admission (24) pour réguler l'écoulement d'un fluide entre un orifice d'alimentation (16) et un orifice d'exploitation (18) et d'autre part une vanne de sortie (26) pour réguler l'écoulement d'un fluide entre l'orifice d'exploitation (18) et un orifice d'évacuation (20). Un actionneur à solénoïde (70) applique une force réglable à un élément de vanne mobile (44) pour fermer la vanne de sortie (26) et ouvrir la vanne d'admission (24). Une force antagoniste résultant de la pression de régime s'oppose à la force réglable. L'élément mobile (44) présente des régions opposées, exposées à la pression de régime pour adapter la force antagoniste à la pression de régime.
