 EMI2.1 
 Wirkung des   ausströmenden   Wassers im unteren   Habnkopf ;   diese Wirkung wird bei Erhöhung des Dampfdruckes bedeutend schneller wachsen als die durch Expansion des Dampfes entstehende Druckdifferenz. 



   Bei Wallungen im Wasserraum dos Kessels ist es beinahe ausschliesslich die dyna-   mische   Wirkung des circulierenden Wassers, welche den Ventilschluss herbeiführt. 
 EMI2.2 
 erreicht, dass bei   Erhöhung   des Dampfdruckes die dynamische Wirkung unabhängig von der, durch den Druckunterschied hervorgerufenen Kraft verringert wird, so dass die 
 EMI2.3 
 Ventil   hinwegatroichondo   Dampf- oder Wassermenge, je nach dem herrschenden höchsten Dampfdruck, durch Änderung der Grösse dieser Durchtrittsöffnung regelt. Zu diesem 
 EMI2.4 
 stellung der schildartigen Verlängerung 8 die Menge des frei über dem   Ventilkörper   hinwegstreichenden Dampfos oder Wassers verändern.

   Bei Durchstossstellung der Spindel, in welcher die ganze Öffnung g freigelegt wird, ist die schildförmige Verlängerung nach 
 EMI2.5 
 zeigt, die   Grösse dar Durchstossöffnung   in der Rippe r dom jeweiligen   Dampfdruck ent-   sprechend herstellt, wie dies in Fig. 6 durch 1, 2 und 3 angedeutet ist. In diesem Falle ist der   schildförmige   Ansatz mit der Spindel fest verbunden oder kann überhaupt fortfallen. 



   PATENT. ANSPRÜCHE : 
1. Wasserstand zeiger mit bei Glasbruch selbstthätig abschliessendem Ventilkörper, dadurch gekennzeichnet, dass im   Ventilgebäuse   eine das Ventil umgebende Rippe mit einer regelbaren   Durchstossöffnung   angeordnet ist.

 EMI2.1
 Effect of the water flowing out in the lower Habnkopf; this effect will grow significantly faster when the steam pressure is increased than the pressure difference resulting from the expansion of the steam.



   With surges in the water space of the boiler, it is almost exclusively the dynamic effect of the circulating water that causes the valve to close.
 EMI2.2
 achieves that when the steam pressure is increased, the dynamic effect is reduced regardless of the force caused by the pressure difference, so that the
 EMI2.3
 Valve wegatroichondo regulates the amount of steam or water, depending on the prevailing highest steam pressure, by changing the size of this passage opening. To this
 EMI2.4
 position of the shield-like extension 8 change the amount of steam or water sweeping freely over the valve body.

   In the piercing position of the spindle, in which the entire opening g is exposed, the shield-shaped extension is after
 EMI2.5
 shows that the size of the penetration opening in the rib r dom produces the respective vapor pressure accordingly, as indicated in FIG. 6 by 1, 2 and 3. In this case, the shield-shaped extension is firmly connected to the spindle or can be omitted at all.



   PATENT. EXPECTATIONS :
1. Water level pointer with a valve body which closes automatically in the event of glass breakage, characterized in that a rib surrounding the valve with an adjustable opening is arranged in the valve housing.

2. Eine Ausführungsform des Wasserstandanzeigers nach Anspruch l, dadurch gekennzeichnet, dass auf der Spindel der zur willkürlichen Bewegung des Ventil körpers dienenden Handhabe ein in die Durchstossöffnung der Rippe hineinragender Ansatz verstellbar angeordnet ist, zum Zwecke, die Grösse der Durchgangsöffnung verändern zu können. 2. An embodiment of the water level indicator according to claim l, characterized in that on the spindle of the handle serving for the arbitrary movement of the valve body a protruding into the piercing opening of the rib is arranged adjustable, for the purpose of being able to change the size of the passage opening.
