Abstract

Elles comprennent un tarage élastique pouvant fermer la communication entre les orifices de la valve; l'ensemble capteur de pression coopère avec le dispositif à soupape et réagit à la pression d'un fluide appliqué dans l'un des orifices. Le mécanisme de commande peut être actionné de façon à surmonter le tarage élastique du dispositif à soupape et pour maintenir cet ensemble ouvert et pour régler l'ensemble capteur de pression de façon que cet ensemble soit actionné par la pression appliquée dans un orifice ou à une pression supérieure à la valeur de consigne pour permettre au groupe de valve de se fermer afin de couper la communication entre les orifices. L'invention peut être utilisée pour tous fluides susceptibles de travailler sur une plage de pression choisie.
