Patent ID: 7334412

Claim:
A turbine, comprising: a swivel-mounted rotationally symmetrical rotor; a compressor mounted along the rotor; a combustion chamber mounted along the rotor; a turbine section mounted along the rotor and formed of a plurality of turbine stages in which each turbine stage comprises mutually interacting blades and vanes which are surrounded by a flow of hot working fluid; and a coolant provided by the compressor for cooling the blades and the vanes, the coolant flowing in a channel along the rotor from the compressor to the turbine section and into which a liquid is adapted to be introduced for cooling, wherein the channel extends outside the rotor such that the liquid is introduced into the channel in a region close to the compressor, wherein a flow channel downstream of the compressor outlet in the direction of flow of the compressor air contains a at least one passing through said flow channel, wherein a radially external end of the at least one is secured on the stator of the turbine and the radially internal end opposite the external end faces the rotor, wherein at least one rib is hollow and a pipe runs in the rib, the pipe communicating on a stator side with a source of liquid and on the rotor side with a nozzle used to introduce the liquid in the channel.
