Abstract

Distributeur comprenant un réducteur de pression monté dans un corps et un organe de commande, propre à modifier le tarage du reducteur, lequel comporte un plongeur propre à être déplacé dans une cavité, laquelle comprend, d'un côté, un logement où sont placés des moyens de tarage du réducteur et, de l'autre côté, un alésage dans lequel peut être déplacée une partie active du plongeur. Le corps 3 du distributeur est réalisé en deux parties 3a, 3b, indépendantes l'une de l'autre et réunies par des moyens d'assemblage A; ces deux parties sont séparées par une surface S traversant le logement 13 relié à la basse pression, mais située au voisinage d'une extrémité de l'alésage 18 relié à la zone sous pression. Application aux distributeurs hydrauliques, notamment pour engins de travaux publics.
