Abstract

Soupape d'injection de combustible pour moteur à combustion interne. Soupape comprenant notamment un siège de soupape partiellement sphérique afin de procurer un bord circulaire de contact avec une soupape sphérique légèrement plus petite portée par l'extrémité libre dune tige flexible; l'extrémite fixe de la tige est fixée dans une armature lâchement supportée ayant un passage central entourant une longueur notable de la tige et apaisant l'écoulement du combustible vers l'ensemble formé de la soupape sphérique et du siège de soupape coopérant
