Abstract

Valve de régulation de pression pour circuits à haute pression. Elle comprend un corps 10 contenant un siège 34 traversé axialement par un alésage 36 d'entrée qui peut etre fermé, par un disque 48 qu'un piston 50 tend à faire porter contre la surface supérieure 35 du siège sous la force d'un ressort 52 constitué de rondelles Belleville. Le canal 88 d'écoulement formé entre les surfaces opposées du siège et du disque est suffisamment important pour provoquer un ralentissement progressif et déterminé de l'écoulement passant entre ces deux éléments. Domaine d'application: appareils de pulvérisation sous haute pression.
