Abstract (en)

[origin: EP0945626A2] The rotor blades are adjusted via a servo drive with an adjusting piston (11). The piston wall (12) overlaps radially with the rotor blades (2) and acts as adjusting ring to hold adjusting journals (24) of eccentric adjusters. When the piston is charged with a pressure medium, the blades are moved into a conveying direction opposite to the original conveying direction, and are loaded in a position corresponding to that direction, via air resistance force.
