Abstract (en)
[origin: EP2189664A2] The machine has a main flow path limited by a hub (3) and a housing (2), and a row of adjustable stator blades (1) arranged in the main flow path. A multi-blade adjusting stator unit is arranged at the hub or at the housing. The stator blades are connected with a common rotating plate (5) and are rotated around a common rotational axis (4) during adjustment of the adjusting stator unit. The stator blades are arranged at a distance from one another and are formed with different shapes with respect to one of parameters such as profile depth, relative curve and stagger angle.
