   Um nun zu verhindern, dass bei Unterbrechung des Stromes für den   einzuschaltenden Motor.   etwa infolge Durchbrennen einer Sicherung, und weiterer Wasserentnahme aus dem Rohrnetz oder aus andern Gründen die Pressluft des   Druckwindkessels entweicht, ist am unteren Teile   des Schwimmers S eine Abdichtung, beispielsweise eine Gummischeibe   k   vorgesehen, die den Abfluss aus dem Druckluftwindkessel W verschliesst. Wenn in dem Augenblick, in dem der Motor eingeschaltet werden soll (welcher Zeitpunkt gewöhnlich mit dem niedrigsten   zulässigen Druck im Druckwindkessel zusammenfällt),   der

  Automatic switching device for pump systems.
 EMI1.1
   The pump drive machine is switched off by a float in the pressure air tank.



   The invention consists in the fact that the swimmer when exceeding his deepest permissible
 EMI1.2
 pump is enough.



   In the drawing, the subject matter of the invention is shown in an exemplary embodiment in FIG
 EMI1.3
 position of the swimmer or is turned off. In the position of the parts shown, the float is in a position in which the switch is brought into the power-on position by means of lever e.



   In order to prevent the motor to be switched on if the current is interrupted. For example, as a result of a fuse being blown and further water extraction from the pipe network or for other reasons, the compressed air of the pressure vessel escapes, a seal, for example a rubber washer k, is provided on the lower part of the float S, which closes the drain from the compressed air vessel W. If at the moment when the motor is to be switched on (which time usually coincides with the lowest permissible pressure in the pressure air vessel), the
 EMI1.4
 nozzle of the pump is attached.

   The pressure line is connected to this cross piece on one side and a hand air pump i can be attached to the other side through which the

PATENT-ANSPRUCH : Seibsttätige Schaltvorrichtung für Pumpenanlagen, bei der die Ein-und Ausschaltung der Pumpenantriebsmaschine durch einen Schwimmer im Druckwindkessel erfolgt, dadurch gekennzeichnet, dass der Schwimmer beim Überschreiten seiner tiefsten zulässigen Stellung den Abfluss des Druckwindkessels unmittelbar oder mittelbar abschliesst. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Self-actuating switching device for pump systems in which the pump drive machine is switched on and off by a float in the pressure air vessel, characterized in that the float directly or indirectly closes the outlet of the pressure air vessel when its lowest permissible position is exceeded. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
