Abstract (en)
[origin: EP1136653A2] The device has a rotor (5) with blades (6) and damper elements (9) between neighboring blades. Each damper element is in friction contact with a first section (1,2) of a first and a second section (3) of a second neighboring blade. The damper elements are positioned between the blades so that the first and the second sections are located in positions, which are at considerable radial distances from each other. Each damper element is prevented from executing a movement at right angles to a radial plane, by guide grooves formed in any of the sections.
