Abstract (en)
The diverting mechanism has a guide vane (9) with an incident flow edge and a departure flow edge, between which a deflection surface is provided that deflects a flowing medium from the incident direction. The guide vane is adjustable in respect of the profile of its deflection surface relative to the direction of incidence. The deflection surface is rotatable and adjustable in its outer shape. Independent claims are also included for the following: (a) a steam turbine with a diverting mechanism (b) a gas turbine with a diverting mechanism (c) a turbocompressor with a diverting mechanism (d) and a method of altering a diverting mechanism in a diffuser.
Abstract (de)
Es wird eine Abströmleiteinrichtung in einem Diffusor (7) einer Strömungsmaschine mit mindestens einem Leitblatt (9) vorgestellt, das eine Anströmkante (13) und eine Abströmkante (14) aufweist zwischen denen eine Umlenkfläche (15) vorgesehen ist. Die Abströmleiteinrichtung lenkt ein Strömungsmedium aus einer Einfallsrichtung (12) um, wobei das mindestens eine Leitblatt hinsichtlich eines Verlaufs seiner Umlenkfläche (15) relativ zur Einfallsrichtung (12) einstellbar ist. <IMAGE>
