Abstract (en)
[origin: EP0947707A2] The cooling air removal device is so formed that the cooling air is removed on one side through apertures (6) on the housing side (20.1) of the diffuser and is fed through cooling air channels (10) to the parts fed with hot gas including also the outer wall of the cuff tube. The compressed air is conducted through cooling air holes (19) in the diffuser blades (3) to the diffuser exterior (20.2).
