Abstract
La présente invention concerne une soupape dotée d'un ensemble de garniture, laquelle soupape peut comprendre une première garniture de tige (37) circonscrivant une première partie d'une tige de soupape, formant un joint d'étanchéité entre la tige de soupape (23) et un ensemble de corps de soupape (12), et qui est disposée dans la seconde partie de perçage (31b). Un premier élément de maintien de garniture (41) peut présenter un collier (43) qui limite un déplacement axial de la première garniture de tige et un premier corps d'élément de maintien définissant une cavité interne. Une deuxième garniture de tige (57) peut circonscrire une seconde partie de la tige de soupape et être disposée dans la cavité interne du premier élément de maintien de garniture. Un second élément de maintien de garniture (67) peut limiter un déplacement axial de la seconde garniture de tige. Un élément de piston (50) peut être disposé axialement entre la première garniture de tige et la seconde garniture de tige, l'élément de piston étant mobile de manière à appliquer une force axiale à une garniture de tige parmi la première garniture de tige et de la seconde garniture de tige.
