Abstract

Régulateur électromagnétique de pression, commandant une pression en fonction de l'intensité d'un signal d'entrée de l'électro-aimant proportionnel. Le régulateur de pression comprend, dans un boîtier commun 14, un distributeur pilote 12 et un distributeur principal 13, dont le tiroir cylindrique creux 22 commande 3 voies, l'orifice 26 de pression réglée étant en regard de l'extrémité ouverte 25 du tiroir creux 22 et du ressort 27 chargeant ce dernier. Le régulateur selon l'invention est compact et permet de régler la pression jusqu'au voisinage du zéro.
