  Sicherheitsvorrichtung zum Schutze   der Kammlager von Dampfturbinen.   
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 



   Man kann nach Fig. 1 auch drei Drücke auf einen Kolben wirken lassen, so dass z. B. die Verschmutzung irgendeines Schaufelteiles durch die Beeinflussung der zwei zunächst liegenden Druckstellen auf die Sicherheitsvorrichtung einwirkt. 



   . Die bei der Einwirkung auf den Regler eintretende   Schliessbewegung   der Ventile vermindert 
 EMI2.1 
 



   PATENT-ANSPRÜCHE :
1. Sicherheitsvorrichtung zum Schutze der   Kammlager   von Dampfturbinen, dadurch   gekenn-   zeichnet, dass die Dampfdrücke mindestens zweier verschiedener Stellen der   Turbinenbeschauflung   bei nicht proportionalen oder bei nicht angenähert proportionalen   Druckänderungen   mittelbar oder unmittelbar auf die   Regel-oder Sicherheitsorgane   der Turbine einwirken.

 <Desc / Clms Page number 2>

 



   You can also let three pressures act on a piston according to Fig. 1, so that, for. B. the contamination of any blade part acts on the safety device by influencing the two pressure points lying next.



   . The closing movement of the valves when the regulator acts is reduced
 EMI2.1
 



   PATENT CLAIMS:
1. Safety device to protect the comb bearings of steam turbines, characterized in that the steam pressures of at least two different points of the turbine blading act directly or indirectly on the control or safety devices of the turbine with non-proportional or non-proportional pressure changes.

Claims (1)

2. Sicherheitsvorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die verschiedenen Beschauflungsdampfdrücko auf einen Differentialkolben wirken, der die Regel-oder Sicherheitsorgane der Turbine beeinflusst. 2. Safety device according to claim 1, characterized in that the various blading steam pressures act on a differential piston which influences the regulating or safety devices of the turbine. 3. Sicherheitsvorrichtung nach Anspruch 2, dadurch gekennzeichnet, dass der Differentialkolben durch Federkräfte stabilisiert ist. 3. Safety device according to claim 2, characterized in that the differential piston is stabilized by spring forces.
