   Es kann auch vorkommen, dass im Vorteilungsnetz ein Rohrbruch solcher Ausdehnung eintritt, dass durch ihn mehr Wasser entweicht, als die Pumpen in den Behälter b zu fördern vermögen und der Wasserstand in letzterem so tief sinkt, dass Druckluft in das Rohrnetz gelangen würde. Um das zu verhüten, ist der Schwimmer unten mit einem Ventilkegel j versehen, der sich, sobald das Wasser in b einen gewissen Tiefstand erreicht hat, auf die Mündung des Zu-und   Abssussrohres 0   setzt und dieselbe   verschliesst.   Er öffnet sich erst dann wieder, wenn nach Beseitigung des Rohrbruches weiterer Wasserzufluss in den Behälter b erfolgt bzw. der Wasserstand in letzterem sich über das festgesetzte Tiefmass erhebt.

   It can also happen that a pipe rupture occurs in the advantage network to such an extent that more water escapes through it than the pumps are able to convey into container b and the water level in the latter sinks so low that compressed air would get into the pipe network. To prevent this from happening, the float is provided at the bottom with a valve cone j which, as soon as the water in b has reached a certain low level, sits on the mouth of the inlet and outlet pipe 0 and closes it. It only opens again when, after the broken pipe has been removed, further water flows into the container b or the water level in the latter rises above the set depth.

 EMI3.2
 pumps in continuous operation auxiliary, suction and pressure pump (s) are connected, the pressure side of which, like that of the main feed pump, is injected through riser pipes to the wind pressure vessel, for the purpose of covering the minimum consumption of liquid at the same time an accumulation of To prevent air and the resulting tearing off of the water columns in the suction lines of the stationary main feed pumps and to prevent the air that is also conveyed exclusively or mainly into the wind pressure vessel
