Abstract (en)

[origin: EP0741234A2] The engine has a housing with an extraction chamber (7) which has an internal radial diffusor (23) positioned on the extraction aperture (6). The ratio between diffusor discharge radius (R2) and intake radius (R1), is larger than 1.3. The diffusor has a running length (L) and an extraction width (H). The ratio of its length to its width is at least 10. A deflection grid (24) is located on the diffusor outlet (26). The diffusor is formed by a wall (9) of the extraction chamber, and a diffusor wall (20). The diffusor wall is fastened in the chamber via guide grooves (21,22).
