Title
(DE) TURBINE MIT VERÄNDERLICHEM DURCHFLUSSQUERSCHNITT.
(EN) VARIABLE AREA TURBINE.
(FR) TURBINE A SURFACE VARIABLE.
Abstract
(EN)
Exhaust gas turbine (10) for driving a charging compressor (12) for an internal combustion engine has movable inlet vanes (48). The vanes (48) are controlled by sensing the inlet and outlet pressure at the vanes and adjusting the vanes in accordance with these pressures in order to maximize turbine efficiency.

(FR)
Une turbine à gaz d'échappement (10) servant à entraîner un compresseur-chargeur (12) d'un moteur à combustion interne possède des pales mobiles d'admission (48). Les pales (48) sont commandées en détectant la pression d'admission et de sortie au niveau des pales et en régulant l'inclinaison des pales en fonction de ces pressions, afin de porter à son maximum le rendement de la turbine.
