Abstract

The centrifugal forces produced by rotation of the disk of the rotor (4) move the inners (22) outside the housings (21) and forcibly apply them to the vanes (5) so as to dampen the vibrations, especially when considerable friction is produced against the outer wall (16). Application for turbo-engines and especially for the large vanes of input blowers.
