Abstract

Cette vanne comprend une soupape d'admission et une soupape de décharge liées entre elles. Selon l'invention, la soupape de décharge possède un siège 20 disposé coulissant sur une rallonge tubulaire 18 du clapet 15 de la soupape d'admission. Le siège 20 est déplaçable sur cette rallonge par un signal de commande (fourni par un ressort 27 par exemple), contre l'action de la pression d'utilisation (orifice 5), laquelle est appliquée au siège 20 -dont la surface d'étanchéité 23 est conique - à travers un canal 17 qui traverse le clapet et la rallonge de la soupape d'admisson.
