Guide vane system with parallel guide vanes (1), valves being arranged in the flow channels (2) between the guide vanes. For the adjustment of the flow, the valves can be adjusted individually, more specifically such that the said individual valves are either completely open or completely closed. For fine adjustment, one or several of the valves can also be moved into an intermediate position. The adjustment of the valves can be effected manually or automatically. In the latter case, there is an adjusting device, for example in the form of a link motion with one or more grooves for journals on actuating arms on the valves. Only one valve at a time can have its position changed by the adjusting device. <IMAGE> |
