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. A fluid flow machine having a flow path (2) bounded by at least one wall on which at least one row of fixed connection blades (6, 7) is arranged, characterized in that in the wall in a region of a row of blades (6, 7 ) at least one fluid removal opening (9) and at least one fluid supply opening (10) are arranged, which are connected by at least one Fluidrückführweg (11), wherein the extent of the fluid supply opening (10) in the circumferential direction is less than the distance between two adjacent blades.
