Abstract

L'invention concerne un circuit magnétique (10) d'électrovanne pour actionner un induit (22) présentant un boulon d'induit (26) et une plaque d'induit (24). Le circuit magnétique (10) comprend un noyau magnétique (12) à base de matériau composite pulvérulent dans lequel est noyée une bobine d'excitation (28). Ladite bobine d'excitation (12) contient un pôle intérieur (40) et un pôle extérieur (42). Un disque polaire (44) recouvrant au moins le pôle extérieur (42) du noyau magnétique (12) et consistant en matériau ferromagnétique se trouve entre le noyau magnétique (12) et l'induit (22).
