Abstract

Dispositif d'entrainement d'une vanne au moyen d'une pompe servant a entrainer une vanne (13) au moyen d'une pression hydraulique produite par une pompe (12) electro-magnetique, comprenant un dispositif d'actionnement servant a entrainer en meme temps une pluralite de charges telles que des vannes. Ce dispositif peut ouvrir ou fermer une pluralite de vannes (13) connectees en serie avec un passage principal par l'intermediaire d'un dispositif d'entrainement a vanne simple, peut commander une vanne de maniere proportionnelle et selective et peut assurer un fonctionnement sur de la pompe.
