Abstract

Die Erfindung betrifft eine Radialpumpe, insbesondere Kühlmittelpumpe für eine Brennkraftmaschine, mit zumindest einer ersten Gruppe (5) von um Achsen (9) parallel zur Laufradachse (1a) schwenkbaren Laufschaufeln (6). Um den Wirkungsgrad zu erhöhen ist vorgesehen, dass die Gruppe (5) von schwenkbaren Laufschaufeln (6) im Bereich des Strömungsaustrittes (22) des Laufrades (1) angeordnet ist, wobei der Gruppe (5) von schwenkbaren Laufschaufeln (6) eine Gruppe (3) mit dem Laufrad (1) fest verbundenen starren Laufschaufeln (4) vorgelagert ist.
