A comparative Considering the Fig. 1 and 2 can be taken that the pivoting position by Pressure on the vane ring 14 is changeable and the vane ring 14 remains in a desired position due to its elastic behavior. The bearing shell 17 includes for this purpose an elastic sleeve 27, which with the Ball surface segment 18 cooperates and in one to the outer Ends of the vanes 16 integrally formed receiving ring 28 of Bearing shell 17 is fitted (see Fig. 1 and 3b).

Die Fig. 1 und 2 zeigen ferner, dass in der Aufnahmevorrichtung 5 ein Strömungskanal 29 zum gleichzeitigen Ansaugen von Umgebungsluft 30 mit Hilfe des Propellers 8 vorgesehen ist. Die Luft 15 strömt nach Verlassen des Strömungskanals 29 durch einen in der Nabe 9 angeordneten, zur Nabenachse X konzentrischen ringförmigen Luftkanal 31 und fließt gemeinsam mit dem Wasserstrom durch die Auslassöffnung 13 (s. Fig. 4b). Der Luftkanal 31 weist innerhalb des Ringspaltes 32 Gebläseschaufeln 33 auf, die das Ansaugen der Luft 30 fördern (siehe Fig. 1 und 4a). Vor der Lufteinströmöffnung 34 des Strömungskanals 29 ist ein Rückflussverhinderer 35 vorgesehen, an den stromauf ein Lufteintrittstutzen 36 angeschlossen ist. Die Luftzufuhr ist durch ein an ein Bedienelement angeschlossenes Ventil wahlweise zu- und abschaltbar (nicht dargestellt).Figs. 1 and 2 further show that in the receiving device 5, a flow channel 29 for simultaneous intake of ambient air 30 with the help of the propeller 8 is provided. The air 15 flows after leaving the flow channel 29 arranged by a hub 9 in the hub axis X. concentric annular air channel 31 and flows together with the Water flow through the outlet opening 13 (see Fig. 4b). The air channel 31 has within the annular gap 32 fan blades 33, the suction of the Air 30 promote (see Fig. 1 and 4a). In front of the air inflow opening 34 of the Flow channel 29, a backflow preventer 35 is provided to the upstream of an air inlet nozzle 36 is connected. The air supply is through a valve connected to an operating element can optionally be switched on and off (not shown).
