Abstract

L'invention concerne un éjecteur à poussée, capable de contrôler la poussée même pour de faibles valeurs de celle-ci. A cet effet, l'éjecteur 15 comporte une valve à aiguille 16 de telle sorte que position de l'aiguille 18, contrôlée par un servo-moteur 21, règle le mélange des flux M1 et M2 en vue de fournir la poussée désirée, même pour des faibles valeurs de celle-ci. L'invention s'applique à toutes les utilisations des éjecteurs de l'art antérieur.
