Abstract

La présente invention concerne une soupape d'injection de carburant (1), notamment une soupape d'injection de carburant destinée à des systèmes d'injection de carburant de moteurs à combustion interne, ladite soupape comprenant : un pointeau de soupape (3) qui coopère avec une surface de siège de soupape (6) pour former un siège étanche ; et un induit (20) venant en prise contre le pointeau de soupape (3), l'induit (20) pouvant se déplacer axialement contre le pointeau de soupape (3), et étant amorti par un élément d'amortissement (32). L'élément d'amortissement (32) comprend un disque de support annulaire (36), au moins un segment d'amortissement (37) constitué d'un élastomère, étant disposé contre au moins une surface frontale (38, 39) du disque de support (36).
