Abstract
Die Erfindung bezieht sich auf eine Strömungsarbeitsmaschine mit zumindest einem Rotor (1) und einer freien Anzahl von Statoren (2), die von einem Fluid durchströmt werden, mit zumindest einer Schaufel, die an schaufelkanalbegrenzenden Oberflächen eine Einrichtung zur Entnahme von Fluid aus dem Strömungspfad und eine Einrichtung zur Fluidzufuhr in den Strömungspfad aufweist (Bifunktionalität), mit zumindest einer Leitung (4) zur Rückführung des entnommenen Fluids an eine stromauf gelegene Position des Strömungspfads und zumindest einer weiteren Leitung (4) zur Heranleitung des zuzuführenden Fluids von einer weiter stromab gelegenen Position des Strömungspfads. The invention relates to a fluid flow machine with at least one rotor (1) and a free number of stators (2) through which a fluid flows, with at least one blade having on the blade channel boundary surfaces means for removing fluid from the flow path and a device for supplying fluid into the flow path (bifunctionality), with at least one line (4) for returning the withdrawn fluid to an upstream position of the flow path and at least one further line (4) for bringing the fluid to be supplied from a further downstream position of the flow path.
