 der Flüssigkeit wird das Ventil D3 geschlossen. Die Flüssigkeit aus dem Rohre B öffnet nun das   Ventil D'und strömt   in die Kammer   J.   Bei der Entleerung der Kammer A oder Al wird das Ventil I bezw. I1 durch den Gasdruck geschlossen gehalten. 



   Fig. 1 zeigt das Ventil I1 geschlossen, bei gefüllter Kammer A1 und das Ventil   I   geöffnet,   bei entlerrter Kammer A. entleerter Kammer A.   



   Ist die Kammer A leer, so kann Druckgas durch die Rohre E und K entweichen. Die Strömungsenergie hat hiebei den Schluss des Ventiles   H   zur Folge. Während des Füllens der Kammer A1 sperrt die   Flüssigkeit eine   Gassäule in dem Rohre G1 ab, die schliesslich unter einem Druck steht, der der Entfernung des   Flüssigkeitsspiegels   von dem unteren Ende der Rohre G entspricht. Dieser Druck unterstützt die Wirkung des durch Rohr G und die leere Kammer A ausströmenden Gases, indem er das Ventil   fl1   zu öffnen, also H zu schliessen trachtet. 



   Statt der Klappen D3 und   D'nach   Fig. 1 lassen sich auch an einer gemeinsamen Spindel angeordnete Ventile D und   J) 1 verwenden,   wobei das eine Ventil sich schliesst, sobald das andere Ventil geöffnet wird. 



   PATENT-ANSPRÜCHE :   1. Druckluftflüssigkeitsheber   mit zwei Kammern, die abwechselnd mit Flüssigkeit gefüllt und dann unter Druck gesetzt werden, dadurch gekennzeichnet, dass nach Entleerung der einen Kammer das einströmende Druckmittel in die Aussenluft entweichen kann und infolge seiner Strömungsenergie das dieser Kammer zugeordnete Drucklufteinlassventil, das mit jenem der anderen Kammer fest verbunden ist, in die Schlussstellung mitreisst und dass gleichzeitig in der zweiten Kammer während des Füllens mit Flüssigkeit ein Überdruck geschaffen wird, der das   Drucklufteinlassventil   der zweiten Kammer im Sinne des   Oeffnens   und somit jenes der ersten   Kammer   im Sinne des Schliessens beeinflusst.

 EMI2.1
 valve D3 is closed to the liquid. The liquid from the pipe B now opens the valve D 'and flows into the chamber J. When the chamber A or A1 is emptied, the valve I or I1 kept closed by the gas pressure.



   Fig. 1 shows the valve I1 closed, with filled chamber A1 and the valve I open, with emptied chamber A. emptied chamber A.



   If chamber A is empty, pressurized gas can escape through pipes E and K. The flow energy causes valve H to close. During the filling of the chamber A1, the liquid shuts off a gas column in the tube G1 which is ultimately under a pressure which corresponds to the distance of the liquid level from the lower end of the tubes G. This pressure supports the effect of the gas flowing out through pipe G and the empty chamber A by opening the valve fl1, i.e. trying to close H.



   Instead of the flaps D3 and D 'according to FIG. 1, valves D and J) 1 arranged on a common spindle can also be used, one valve closing as soon as the other valve is opened.



   PATENT CLAIMS: 1. Compressed air liquid lifter with two chambers that are alternately filled with liquid and then pressurized, characterized in that after one chamber has been emptied, the pressure medium flowing in can escape into the outside air and, due to its flow energy, the compressed air inlet valve assigned to this chamber, which is firmly connected to that of the other chamber, carries with it into the final position and that at the same time an overpressure is created in the second chamber while filling with liquid, which opens the compressed air inlet valve of the second chamber and thus that of the first chamber in the sense of Closing influences.
