A cover member (100) defining a rotor (12) chamber adjacent to a rotor (12) wheel that supports a rotating blade in a turbine includes a first aperture (130) for introducing a cooling gas stream (110) into the rotor (12) chamber, and a second aperture (130) positioned in a radially outward portion (140) of the cover member (100) for allowing a portion of the cooling gas stream (110) to exit the rotor (12) chamber. The portion of the cooling gas stream (110) exiting the rotor (12) chamber carries dirt particles to purge the rotor (12) chamber. |
