Abstract

Afin de maintenir ouvert ou fermé le siège de soupape dans une soupape à solénoïde conventionnelle, il est nécessaire d'alimenter continuellement en courant électrique le bobinage électromagnétique, ce qui augmente considérablement la consommation d'énergie. Afin de résoudre ce problème, la soupape à solénoïde ci-décrite comporte un bobinage électromagnétique; un induit qui se compose d'un aimant permanent pouvant se déplacer axialement dans le passage central d'un bobinage électromagnétique, et qui est monté à l'extrémité côté siège de soupape d'un passage d'écoulement avec un corps de soupape destiné à être utilisé essentiellement pour ouvrir et fermer le siège de soupape; un pôle magnétique fixe qui est placé dans une position où le bobinage électromagnétique est alimenté pour attirer l'induit, et qui se compose d'un matériau magnétique, de sorte que l'induit soit attiré vers le bobinage électromagnétique par sa propre force magnétique même lors de l'arrêt de l'alimentation du bobinage électromagnétique en courant électrique; un élément qui sollicite constamment l'induit contre le siège de soupape. Cette soupape à solénoïde, pouvant interrompre ou permettre l'écoulement d'un fluide, peut être utilisée comme moyen de régulation du débit de ce fluide.
