   Die Wirkungsweise der Einrichtung ist nun folgende : Der in die Turbine strömende Abdampf hebt, solange er mehr   als Atmosphärendruck   besitzt, das Rückschlagventil g an, wobei zugleich

  Der Dampf wird dadurch abgesperrt und ein Durchgehen der Maschine verhindert. Das Schnell-   schlussventil 1t   der Frischdampfzuleitung wird durch dasselbe Gestänge m, welches die Aufhebung der Sperrung des Hammers k bewirkt, zu gleicher Zeit oder schon etwas früher geschlossen.

   The mode of operation of the device is as follows: The exhaust steam flowing into the turbine, as long as it has more than atmospheric pressure, raises the check valve g, and at the same time
 EMI2.1
 



  This shuts off the steam and prevents the machine from running away. The quick-acting closing valve 1t of the live steam supply line is closed at the same time or a little earlier by the same linkage m which effects the lifting of the locking of the hammer k.

Claims (1)

gekennzeichnet, dass ein mit einem Kolben oder einer Membran verbundenes, vom Dampf angehobenes Rückschlagventil mit einem unter Überlast stehenden, für gewöhnlich durch einen Sperrhebel in gespannter Lage gehaltenen Hammer derart vereinigt ist, dass bei einem Sinken des Dampfdruckes unter ein Mindestmass das Rückschlagventil selbsttätig schliesst, wogegen bei einer zu reichlichen Dampfzuführung der Hammer durch den Regler freigegeben und damit das Rückschlagventil plötzlich geschlossen wird. characterized in that a non-return valve connected to a piston or a membrane and lifted by the steam is combined with a hammer which is under overload and is usually held in a cocked position by a locking lever in such a way that the non-return valve closes automatically when the steam pressure drops below a minimum, on the other hand, if there is too much steam, the regulator releases the hammer and the non-return valve is suddenly closed.
