Abstract

L'invention concerne un dispositif de réglage électromagnétique pour soupape de commande hydraulique, comprenant un tube de pression (1) et l'induit (4) d'un électroaimant, cet induit ayant un mouvement axial dans une cavité (3) du tube de pression (1). La cavité (3) contient un fluide pour amortir le mouvement de l'induit (4). A une extrémité de la cavité (3), un dispositif (5) sert à purger le tube de pression (1). Ce dispositif (5) de purge comporte un élément de purge (6) monté pivotant dans le tube de pression (1) qu'il ferme hermétiquement. Cet élément est constitué d'au moins une conduite débouchant dans la cavité et conduisant dans l'environnement du tube de pression (1). Une extrémité de conduite (8) ouvrant dans la cavité (3) est disposée sur le diamètre extérieur de la cavité (3), dans la zone d'une extrémité qui est opposée à l'extrémité (8) du tube de pression (1) reliée à la soupape de commande. En outre, la conduite (7) peut être bloquée relativement à l'environnement du tube de pression (1).
