Abstract (en)
[origin: EP2362070A1] The drive device has an annular flow channel section (23) surrounded by a blade carrier (22), where the section is extended along a center line (24) of the blade carrier. The blades (19) are provided in the section in a ray-like manner for forming a ring. Each of the blades is pivoted about a longitudinal axis (31) and has a pin (26) which extends into the blade carrier. The pin is coupled to an adjustment ring (28) which encloses the blade carrier and is driven by a motor.
