Abstract

Dans une soupape pilote actionnée par une palette, la pression de sortie de la soupape dépend de la force exercée par la palette, et est proportionnelle à celle-ci. La soupape comprend un corps de soupape (33) avec une chambre supérieure (35) et une chambre inférieure (37), ainsi qu'un passage interconnecteur de gaz (39). Une poupée (47) sollicitée par un ressort et agencée dans la chambre inférieure comprend une surface primaire d'étancheité (51) pour obturer la chambre inférieure et une surface secondaire d'étanchéité (63) en contact avec un élément à palette (65) agencé dans la chambre supérieure. L'élément à palette a un alésage intérieur (85) qui mène à un orifice d'échappement (87) à l'extrémité supérieure de l'élément à palette qui traverse une ouverture dans le corps de la soupape. L'élément à palette est soutenu dans la chambre supérieure par un diaphragme (77) sensible à la pression. La zone du diaphragme et les zones d'étanchéité primaire et secondaire coopèrent pour fournir une pression de gaz de sortie proportionnelle à la force extérieure appliquée par la palette sur l'élément à palette.
