Abstract

Ce dispositif de commande de distribution de fluide comprend un corps 11 formé d'une matière magnétisable et qui délimite un siège 20. Le corps porte un aimant permanent 21 qui attire un obturateur 13, également réalisé en une matière magnétisable, en contact avec le siège afin d'empêcher l'écoulement du fluide à travers un orifice de sortie 12. Des moyens électro-magnétiques qui comprennent un organe externe annulaire 25 relié à l'obturateur et un organe interne 28 qui porte des bobinages assurent l'écartement de l'obturateur par rapport au siège lorsqu'un courant électrique est appliqué au bobinage.This fluid distribution control device comprises a body 11 formed of a magnetizable material and which delimits a seat 20. The body carries a permanent magnet 21 which attracts a shutter 13, also made of a magnetizable material, in contact with the seat. in order to prevent the flow of fluid through an outlet orifice 12. Electromagnetic means which comprise an annular external member 25 connected to the shutter and an internal member 28 which carries coils ensure the separation of the valve. shutter relative to the seat when an electric current is applied to the winding.
