Abstract

Une turbine à géométrie variable comprend une roue de turbine montée pour rotation autour d'un axe de turbine dans un logement, le logement délimitant une entrée annulaire entourant la roue de turbine et délimitée entre des première et seconde parois latérales d'entrée; et un manchon cylindrique axialement mobile sur l'entrée annulaire afin de faire varier la taille d'une voie d'écoulement de gaz dans l'entrée; l'entrée annulaire est séparée en trois passages d'entrée axialement décalés par deux, ou plus, parois de passage d'entrée disposées entre les première et seconde parois latérales d'entrée.
