  Luftpumpe mit kreisendem Flüssigkeitsring. 



   Bei Luftpumpen, bei denen das im Gehäuse   exzentrisch gelagerte Flügelrad in   einen durch die Fliehkraft gehaltenen Flüssigkeitsring eintaucht und durch   Vergrössern   und Verkleinern der durch die Flügel, die seitlichen Steuerscheiben und den Flüssigkeitsring gebildeten Kammern Luft angesaugt und ausgestossen wird, muss das   Flügelrad genau   zwischen den Steuerscheiben geführt werden. Das ist wichtig, damit einerseits die Verluste, die durch die Undichtigkeit zwischen Steuerscheiben und Flügelrad auftreten, möglichst klein bleiben und damit andrerseits der Verschleiss, der bei axialen Verschiebungen des Rades durch die Reibung der   bewegten   Teile aufeinander entstehen könnte, möglichst vermieden wird.

   Eine genaue und dauernd gleich- 
 EMI1.1 
 zwischen Steuerscheiben und Rad naturgemäss sehr gering sein muss. Jedenfalls muss die Welle durch besondere, genau einstellbare Drucklager gesichert werden, was einen   verwickelten Authau   erfordert und die Herstellungskosten erheblich erhöht. 



   Um dies zu vermeiden. wird nach der Erfindung die Welle der Pumpe im Flügelrad axial verschiebbar angeordnet. Das Rad a wird lose auf den   Keil/'der Welle b aufgesetzt,   so dass es in tangentialer Richtung von der Welle mitgenommen wird. aber in axialer Richtung auf dem Keil leicht beweglich ist. Wenn nun auch starke.   Axiaklrücke   auf die   Welle   ausgeübt werden, 
 EMI1.2 
 eine möglichst reibungslose Lage einzustellen sucht.

  Air pump with rotating liquid ring.



   In the case of air pumps, in which the impeller mounted eccentrically in the housing is immersed in a liquid ring held by centrifugal force and air is sucked in and expelled by enlarging and reducing the chambers formed by the blades, the lateral control discs and the liquid ring, the impeller must be exactly between the control discs be guided. This is important so that, on the one hand, the losses that occur due to the leakage between the control disks and the impeller remain as small as possible and, on the other hand, the wear that could arise when the wheel is axially displaced due to the friction between the moving parts is avoided as far as possible.

   An exact and constant
 EMI1.1
 between the control discs and the wheel must naturally be very small. In any case, the shaft must be secured by special, precisely adjustable thrust bearings, which requires a complicated structure and increases manufacturing costs considerably.



   To avoid this. the shaft of the pump is arranged axially displaceably in the impeller according to the invention. The wheel a is loosely placed on the wedge / 'of the shaft b so that it is carried along by the shaft in the tangential direction. but is easily movable in the axial direction on the wedge. Even if strong. Axial pressures are exerted on the shaft,
 EMI1.2
 seeks to adjust the situation as smoothly as possible.
