Abstract

Strömungsarbeitsmaschine mit einem Strömungspfad (2), welcher durch zumindest eine Wandung begrenzt wird, an welcher zumindest eine Reihe von Schaufeln (6, 7) mit fester Verbindung angeordnet ist, dadurch gekennzeichnet, dass in der Wandung in einem Bereich einer Schaufelreihe (6, 7) zumindest eine Fluidentnahmeöffnung (9) und zumindest eine Fluidzufuhröffnung (10) angeordnet sind, welche durch zumindest einen Fluidrückführweg (11) verbunden sind, wobei die Erstreckung der Fluidzufuhröffnung (10) in Umfangsrichtung geringer als der Abstand zweier benachbarter Schaufeln ist.
