Abstract

Es wird ein Drehschieber (1) und eine Turbinenanlage mit einem solchen Drehschieber (1) vorgeschlagen, wobei durch den Drehschieber (1) bezüglich eines den Drehschieber (1) durchströmenden Mediums Parameter nach oben erweitert, Strömungsquerschnitte optimiert und Strömungsverluste minimiert sind. Der Drehschieber (1) weist einen Drehring (2) und einen Festring (3) auf, die in Ausdehnungsrichtung einer Zentralachse (4) des Drehschiebers (1) stumpf kegelförmig mit einem jeweils zugehörigen Kegelmantel (7; 8) ausgebildet sind und jeweils Durchgangsöffnungen (5; 6) auf dem jeweils zugehörigen Kegelmantel (7; 8) angeordnet haben.
