Abstract
For the purpose of separating dust particles inside a cooling system of a rotor, fitted with moving blades, of a turbo-machine, a device is arranged upstream of the moving blades to be cooled and in the region of the rotor outer surface. The device has at least one feed channel through which a coolant flows, and is directed in the radial direction such that the dust particles located in the coolant accumulate on the side accelerating in the direction of rotation of the rotor. These dust particles subsequently pass into a separation chamber operationally connected to the feed channel and in which they are captured in order then to be discharged.
