 dass   dio   Öffnung des Rohres 4 frei wird und der Dampf durch dieses Rohr 4 unbehindert entweichen kann, ohne Wasser aus dem Standrohr   mitzureissen   oder herauszuschleudern. Von einem bestimmten Druck an ist also bei dieser Vorrichtung der Luftzuführungsweg durch die Klappe geschlossen, so dass erst dann ein Öffnen derselben stattfinden kann, 
 EMI2.1 
 genommen hat, dass bei fallendem Wasser im Behälter 6 und im Schenkel 2 des Standrohres auch der Schwimmer 7 fällt, der seinerseits wieder den Hebel   10,   die Kette 11 und die   Luftrcgplungsktappe   bewegt.

   Das Öffnen der   Luftzuführungsklappc geschieht   jedoch nur von einem ganz bestimmten Druck an, was gleichbedeutend ist mit der Lage des Schwimmers im Behälter C oder dem Stande des Wasserspiegels in demselben. Durch das Fallen des 
 EMI2.2 
 dos Dampfes von dem Schenkel 1 nach dem Rohr 4 wieder abgesperrt ist, weiterer Dampf also nicht mehr entweichen kann. Ist der Druck soweit gefallen, dass die Klappe   allmählich   geöffnet wird, so strömt neue Verbrennungsluft in die Feuerung, wodurch der normale Betrieb wieder hergestellt ist.

 that the opening of the pipe 4 becomes free and the steam can escape unimpeded through this pipe 4 without dragging or hurling water out of the standpipe. From a certain pressure onwards, the air supply path through the flap is closed in this device, so that it can only then be opened.
 EMI2.1
 has taken that when water falls in the container 6 and in the leg 2 of the standpipe, the float 7 also falls, which in turn moves the lever 10, the chain 11 and the air return cap.

   The opening of the Luftzuführungsklappc happens only from a very specific pressure, which is equivalent to the position of the float in the container C or the level of the water in the same. By falling the
 EMI2.2
 dos steam is shut off again from the leg 1 after the pipe 4, so further steam can no longer escape. If the pressure has fallen so far that the flap is gradually opened, new combustion air flows into the furnace, which restores normal operation.
