Abstract

Injecteur (1) de carburant gazeux pour un moteur (E) à combustion interne et présentant : une tuyère (3) d’injection ; un corps (4) de support ; une soupape (7) d’injection configurée pour réguler le flux de carburant à travers la tuyère (3) d’injection et dotée d’un obturateur (9) mobile disposé à l’extérieur du corps (4) de support et d’un siège (10) de soupape ; et un actionneur (6) configuré pour déplacer l’obturateur (9) entre une position de fermeture de la soupape (7) d’injection dans laquelle l’obturateur (9) est pressé contre le siège (10) de soupape et une position d’ouverture de la soupape (7) d’injection dans laquelle l’obturateur (9) est séparé du siège (10) de soupape afin de créer un conduit (11) d’injection à travers lequel s’écoule le carburant gazeux et présentant un tronçon initial convergent et un tronçon final divergent.
