Claims (11)

  1. Turbine variabler Geometrie, Folgendes beinhaltend:
    ein Turbinenrad (5), montiert zur Rotation um eine Turbinenachse innerhalb eines Gehäuses (1), wobei das Gehäuse (1) einen ringförmigen Einlass (9) definiert, der das Turbinenrad (5) umgibt und zwischen einer ersten (32) und einer zweiten (33) Einlass-Seitenwand definiert ist; und
    eine zylindrische Hülse (30), die axial durch den ringförmigen Einlass (9) beweglich ist, um die Größe eines Gasströmungswegs durch den Einlass (9) zu variieren;
    wobei der ringförmige Einlass (9) in mindestens zwei axial verschobene Einlassdurchgänge (39) unterteilt ist;
    wobei der Innendurchmesser der Hülse (30) größer ist als der Innendurchmesser der Einlassdurchgänge (39);
    wobei die axial bewegliche Hülse (30) über im Wesentlichen die gesamte axiale Breite des ringförmigen Einlasses (9) beweglich ist, um den Gasströmungsweg durch den ringförmigen Einlass (9) im Wesentlichen oder ganz zu verschließen.
  2. Turbine variabler Geometrie nach Anspruch 1, bei welcher der Innendurchmesser der Hülse (30) kleiner ist als der Außendurchmesser der Einlassdurchgänge (39) oder im Wesentlichen identisch mit diesem.
  3. Turbine variabler Geometrie nach Anspruch 1, bei welcher der Innendurchmesser der Hülse (30) größer ist als der Außendurchmesser der Einlassdurchgänge (39).
  4. Turbine variabler Geometrie nach einem der vorhergehenden Ansprüche, bei welcher die Hülse (30) axial durch den ringförmigen Einlass (9) in einer Richtung zur zweiten Einlass-Seitenwand (33) beweglich ist, um so die Größe des Gasströmungswegs durch den Einlass (9) zu reduzieren, und wobei mindestens ein Abschnitt eines Endes der Hülse (30), welche näher an der ersten Einlass-Seitenwand (32) als an der zweiten Einlass-Seitenwand (33) liegt, konfiguriert ist, um Gasen gegenüber exponiert werden zu können, die im Gebrauch durch den ringförmigen Einlass (9) strömen.
  5. Turbine variabler Geometrie nach einem der Ansprüche 1 bis 3, bei welcher die Hülse (30) axial durch den ringförmigen Einlass (9) in einer Richtung zur zweiten Einlass-Seitenwand (33) beweglich ist, um so die Größe des Gasströmungswegs durch den Einlass (9) zu reduzieren, und wobei mindestens ein Abschnitt eines Endes der Hülse (30), welche näher an der ersten Einlass-Seitenwand (32) als an der zweiten Einlass-Seitenwand (33) liegt, konfiguriert ist, um sich während der axialen Bewegung der Hülse (30) durch den ringförmigen Einlass (9) zwischen der ersten (32) und der zweiten (33) Einlass-Seitenwand zu befinden.
  6. Turbine variabler Geometrie nach einem der vorhergehenden Ansprüche, bei welcher die Hülse (30) eine geringe radiale Dicke besitzt.
  7. Turbine variabler Geometrie nach Anspruch 1, bei welcher die Hülse (30) eine radiale Dicke besitzt, die geringer ist als die axiale Breite des ringförmigen Einlasses (9).
  8. Turbine variabler Geometrie nach einem der Ansprüche 1 bis 6, bei welcher der ringförmige Einlass (9) in mindestens zwei axial verschobene Einlassdurchgänge (39) durch mindestens eine ringförmige Umlenkung (38) geteilt wird, die mit einem axialen Abstand von der ersten (32) und der zweiten (33) Einlass-Seitenwand angeordnet ist.
  9. Turbine variabler Geometrie nach Anspruch 8, bei welcher Einlass-Laufräder (37) sich axial über mindestens einen der axial verschobenen Einlassdurchgänge (39) erstrecken, und wobei wahlweise der Mindestabstand zwischen einer Umlenkung (38) und dem Turbinenrad (5) geringer ist als der Mindestabstand zwischen einem benachbarten Laufrad (37) und dem Turbinenrad (5).
  10. Turbine variabler Geometrie nach Anspruch 9, bei welcher die auslaufenden Kanten von mindestens einigen der Laufräder (37), welche sich über einen der axial verschobenen Einlassdurchgänge (39) erstrecken, auf einem anderen Radius zu den auslaufenden Kanten von mindestens einigen der Laufräder (37) liegen, welche sich über einen anderen der axial verschobenen Einlassdurchgänge (39) erstrecken.
  11. Turbine variabler Geometrie nach einem der Ansprüche 1 bis 7, bei welcher der ringförmige Einlass (9) in eine ringförmige Anordnung von im Wesentlichen rohrförmigen Einlassdurchgängen (39) aufgeteilt wird, welche sich im Allgemeinen zum Turbinenrad (5) erstrecken, wobei die ringförmige Anordnung von Einlassdurchgängen (39) mindestens drei axial verschobene Einlassdurchgänge (39) beinhaltet.
