<p>The removal of cooling air from the diffuser part of a radial stage of a compressor of a gas turbine is provided. The end stage of the compressor has a radial rotor disk (2) with a bladed diffuser (3). With the corresponding fastening elements (7) for the parts (20.1, 20.2) on the diffuser housing side, the diffuser blading (3) is used at the same time to connect the vane support (1) to the rear bearing housing (21). Compressed cooling air can be removed through either/both round holes (6.1) or/and slots (6.2), which are milled on the suction side of the diffuser vane (3). Through the removal openings (6.1, 6.2), the cooling air enters the blind holes (19) of the diffuser vane (3) and then further, through holes (19.1) in the diffuser housing outside (20.2), the cooling air discharge (10) arranged in the compressor housing.</p> |
