 wenn der   Kesseldruok     grösser   bezw. kleiner wird als normal, so dass unter allen Umständen der
Druck des gedrosselten, zu den Stopfbüchsen strömenden Dampfes stets auf konstanter Hohe erhalten wird und von dieser Seite eine Verschlechterung des Vakuums nicht zu befiirehten ist. 



   PATENT-ANSPRÜCHE :
1. Selbsttätige Regelung des Dampfdruckes in den Stopfbüchsen von Dampfturbinen, dadurch gekennzeichnet, dass man den Dampf vor Erreichung der Stopfbüchsen auf die grössere
Endfläche eines mit einem   Drosaelschieber   verbundenen Differentialkolbens und auf dessen entgegengesetzte Endfläche kleineren Durchmessers eine fortwährend fliessende Druckflüssigkeit mit konstantem Druck wirken lässt, so dass eine   durch Änderung der Druckdifferenz infolge Steigens   oder Fallens des Kesseldruckes oder des Druckes in den Stopfbuchsen hervorgerufene Bewegung ) des Differentialkolbens in der einen oder anderen Richtung die Drosselung verstärkt bezw. schwächt und somit den Druck in den Stopfbüchsen konstant oder wenigstens annähernd konstant erhält.

 if the boiler pressure is greater or becomes smaller than normal, so under all circumstances the
The pressure of the throttled steam flowing to the stuffing boxes is always maintained at a constant level and a deterioration in the vacuum is not to be expected from this side.



   PATENT CLAIMS:
1. Automatic regulation of the steam pressure in the stuffing boxes of steam turbines, characterized in that the steam before reaching the stuffing boxes on the larger
End surface of a differential piston connected to a Drosael slide and on its opposite end surface of smaller diameter allows a continuously flowing hydraulic fluid to act at constant pressure, so that a movement of the differential piston caused by a change in the pressure difference due to rising or falling of the boiler pressure or the pressure in the stuffing boxes) of the differential piston one or the other direction the throttling increased BEZW. weakens and thus keeps the pressure in the stuffing boxes constant or at least approximately constant.
