Abstract

L'invention concerne un groupe de suralimentation (10, 10', 10') à plusieurs étages pour un moteur à combustion interne, à alimenter avec un fluide du moteur à combustion interne, notamment des gaz d'échappement, comprenant au moins : une turbine haute pression (1) et une turbine basse pression (2) disposée fluidiquement après la turbine haute pression (1), sachant qu'une sortie de fluide (1.1) de la turbine haute pression (1) est reliée fluidiquement à une entrée de fluide (2.1) de la turbine basse pression (2), et qu'il est prévu une alimentation de mélangeage (3, 15, 17) pour un fluide de dérivation (13). L'invention vise à améliorer fluidiquement le comportement d'écoulement entre la sortie de fluide (1.1) de la turbine haute pression (1) et l'entrée de fluide (2.1) de la turbine basse pression (2), et donc à améliorer le rendement du groupe de suralimentation (10, 10', 10') en réduisant les pertes d'écoulement. A cet effet, selon l'invention, l'alimentation de mélangeage (3, 15, 17) est disposée entre la sortie de fluide (1.1) de la turbine haute pression (1) et l'entrée de fluide (2.1) de la turbine basse pression (2), et la turbine haute pression (1) est réalisée sous la forme d'une turbine radiale et la turbine basse pression (2) sous la forme d'une turbine axiale. On obtient également une optimisation de l'encombrement par le fait qu'un circuit de stabilisation (5) entre la sortie de fluide (1.1) de la turbine haute pression (1) et l'entrée de fluide (2.1) de la turbine basse pression (2) est réalisé relativement peu encombrant, voire peut être supprimé.
