Abstract

Bei einer axial durchströmten Turbomaschine mit mindestens einer Anzapfkammer (7) im Gehäuse (3), wird ein Teil des zum Betrieb der Turbomaschine verwendeten Arbeitsmittels über Entnahmeöffnungen (6) abgeführt.In the case of an axially flowing turbomachine with at least a tap chamber (7) in the housing (3), a part of the Operation of the turbomachine used work equipment Removal openings (6) removed.

Im Innern der Anzapfkammer (7) an der Entnahmeöffnung (6) ist ein im wesentlichen radial ausgedehnter Diffusor (23) angebracht.Inside the tap chamber (7) at the removal opening (6) an essentially radially extended diffuser (23) appropriate.

Der Diffusor (23) wird durch eine Anzapfkammerwand (9) der Anzapfkammer (7) und eine Diffusorwand (20) gebildet.
