Abstract

The turbine has a regulating wheel (13) arranged on a rotor (2) between another regulating wheel (7) and a reaction part (3), where the former regulating wheel is provided with a blade. A flow cross section (18) of the former regulating wheel is connected with a damping guide by a flow path (16) parallel to another flow path (14) guided by the latter regulating wheel. The flow cross section of the former regulating wheel is connected with a flow cross section (12) of the reaction part by third flow path (17) combined with a flow cross section of the latter regulating wheel.
