Abstract

Die Erfindung betrifft eine Turbine (10) für einen Abgasturbolader einer Verbrennungskraftmaschine, mit einem Turbinengehäuse (12), welches einen Aufnahmeraum (14) zum wenigstens bereichsweisen Aufnehmen eines Turbinenrads (16) der Turbine (10) umfasst, und mit einer Stelleinrichtung (36), mittels welcher ein Strömungsquerschnitt in einem Turbinenradaustrittsbereich (38) stromab des Turbinenrads (16) variabel einstellbar ist, wobei die Stelleinrichtung (36) eine Mehrzahl von unabhängig voneinander, relativ zum Turbinengehäuse (12) verstellbaren Stellelementen (40) umfasst, mittels welchen der Strömungsquerschnitt variabel einstellbar ist.
