Abstract

L'invention concerne une soupape comprenant un élément de soupape (72) qui est déplaçable dans le sens de son axe longitudinal (73), qui fait saillie dans une chambre de pression de soupape (77) et qui présente, dans la chambre de pression de soupape (77), sur une face frontale perpendiculaire à son axe longitudinal (73) une surface d'étanchéité (81) grâce à laquelle l'élément de soupape coopère avec un siège de soupape (79) perpendiculaire à son axe longitudinal (73) pour la fermeture au moins très étendue, par rapport à la chambre de pression de soupape (77), d'un orifice (78) entouré par le siège de soupape (79). Une liaison (64) vers une zone basse pression se rattache à l'orifice (78). L'élément de soupape (72) comprend un tenon (83) qui fait saillie dans la liaison (64) et qui sert à conduire le liquide s'écoulant hors de la chambre de pression de soupape (77) lorsque la surface d'étanchéité (81) de l'élément de soupape (72) est relevée par rapport au siège de soupape (79), de sorte que pratiquement presque aucune force résultante n'est exercée par ce liquide sur l'élément de soupape (72) dans le sens de son axe longitudinal (73).
