Abstract

The arrangement for damping the blade vibrations in a turbine 1 which interacts with a gaseous medium, for example a gas turbine, the turbine in the turbocharger of an internal combustion engine or the like, by utilizing a relatively rigid wire unit or the like 4, which can be fitted in through 3 and connects the blades 2 and comprises two or more annular elements 4a-4k which are arranged in such a manner in relation to one another that the joining point between the ends 4', 4'' in each element is located in essentially different places in relation to the circumference of the wire unit or the like 4. Said annular elements 4c-4k are at least in part arranged within one another. <IMAGE>
