Title (EN) VALVE SYSTEM
(FR) SYSTÈME DE SOUPAPE
Abstract:
(EN) The present invention is directed to a valve that has an orifice closing member adjacent to an orifice through which fluid can flow, a displacement member having a first portion and a second portion, where the first portion is adjacent to the orifice closing member when the valve is in an open position, a first magnet and a second magnet where the first and second magnets are sufficiently proximate to the displacement member to exert a magnetic force on the displacement member, and an actuator for generating a magnetic field to move the displacement member toward the first magnet, cause the first portion to press against the orifice closing member, and cause the orifice closing member to close the orifice.
(FR) L'invention concerne une soupape comportant un élément de fermeture d'orifice adjacent à un orifice à travers lequel un fluide peut s'écouler, un élément de déplacement comprenant une première partie et une seconde partie, la première partie étant adjacente à l'élément de fermeture d'orifice quand la soupape est dans une position d'ouverture, un premier aimant et un second aimant, le premier et le second aimant étant suffisamment proches de l'élément de déplacement pour exercer une force magnétique sur l'élément de déplacement, et un actionneur pour générer un champ magnétique pour déplacer l'élément de déplacement vers le premier aimant, amener la première partie à s'appuyer contre l'élément de fermeture de l'orifice, et entraîner la fermeture de l'orifice par l'élément de fermeture de l'orifice.
