Abstract

Pompe d'un type unique pouvant être monté aussi bien en amont qu'en aval d'un régulateur de pression, grâce à une soupape de commande incorporée. Le carter 1 contient une pompe 2 avec un cylindre 3 muni d'une soupape de pression dont le siège 4 est annulaire et l'élément de fermeture comporte un plateau 5 soumis à un ressort 7. Le piston 15 de la pompe est relié au piston de travail 20 soumis d'une part au ressort 21 et d'autre part à la pression d'un régulateur agissant au travers de la chambre de changement de pression 22. La soupape de commande 30 permet d'adapter la pompe au cas de branchement considéré, avant ou apres le régulateur.
