Abstract

L'addition a pour objet des perfectionnements apportés à une soupape du type en champignon refroidie par circulation d'un fluide réfrigérant. Selon l'invention, les conduits de refroidissement dans la tige et dans la tête de la soupape, présentent une section libre de passage pour un fluide de refroidissement tel que de l'huile sensiblement uniforme, ce qui permet d'éviter des risques de cracking provoqués par la surchauffe d'huile stagnante. L'addition s'applique notamment aux moteurs à combustion interne.
