Abstract

Système d'injection d'une chambre de combustion de turbomachine comportant une buse d'injection de carburant assurant la vaporisation du carburant dans la chambre de combustion et un ensemble mélangeur/déflecteur coaxial à cette buse d'injection et qui réalise le mélange comburant/carburant et le diffuse dans la chambre de combustion, cet ensemble mélangeur/déflecteur comportant une vrille primaire (40) et une vrille secondaire (42) disposés axialement à une distance déterminée l'un de l'autre et séparés par un dispositif à venturi (44) disposé coaxialement à la buse d'injection, la vrille primaire étant fixée solidairement à la buse d'injection et séparée de celle-ci d'une distance radiale constante, déterminée de telle sorte que le carburant vaporisé par la buse d'injection ne peut en aucune façon impacter sur la vrille primaire. De préférence, le dispositif à venturi comporte une surface interne (44A) présentant sur une partie amont une discontinuité de pente P.
