1. Anordning vid sädana apparater för inblandning och lösning av gaser i vätskemassor, vilka av ett axial-pumphjul (22) uppfordras genom en i huvudsak vertikal stigledning (20), vars nedre ände uppvisar ett inlopp för vätskan och vars Övre ände bildar ett avlopp för den pumpade vätskan och begränsas av ledytar (78), som avlänka vätskan i radiell riktning frän stig-ledningens (20) axel, varvid pumphjulets drivaxel (4) är koaxial med stiglednlngen (20) och driver axial-pumphjulet (22) frän ett ovanför vätskemassan placerat drivaggregat kännetecknad av att driv-axeln (4) är omsluten av en stationar ledning (16) vars innervägg tillsammans med drivaxeln (4) begransar en gaskommunik ationsspa 11 (17), vars’nedre ände mynnar i stig 1 edningen (20) via ätminstone en utät frän appa-ratens centrumlinje riktande u tstromn i ngspassage (19), varvid nämnda gaskommunik ationsspa11 (17) öppet kommu-nicerar med en gaskälla, exempelvis den omgivande atmos fären.
2. Anordning enligt patentkravet 1, k ä n n e,t e c k -n a d av att gaskommunikationsspalten (17) mynnar ko-axialt med drivaxeln (4) i den stationära ledningens (16) nämnda nedre ände samt att pa ett mindre avständ under nämnda mynning är pä drivaxeln koaxialt fast en i huvudsak rotationssymmentrisk kropp, vars mot nämnda mynning vettande ände uppvisar en ringformig yta, vars yttre diameter är större än den stationära ledningens (16) yttre diameter vid änden.
3. Anordning enligt patentkravet 2, känneteck-n a d av att den stationära ledningens (16) nedre ändyta tillsammans med den rotatιonssymmetrιska kroppens ringformiga yta begransar en ringformig spalt (19) som bildar nämnda gasutströmninqspassage. II
