Patentirt im Deutschen Reiche vom 25. September 1881 ab.Patented in the German Empire on September 25, 1881.

Die dargestellte Neuerung ist anwendbar bei allen Reducirventilen, bei welchen die Höhe des reducirten Druckes durch Drosselung der Durchströmungsöffnung mittelst Einwirkung des reducirten Druckes selbstthätig regulirt wird.The innovation shown is applicable to all reducing valves in which the height of the reduced pressure by throttling the flow opening by means of the action of the reduced pressure is automatically regulated.

Das drosselnde Ventil, in der Zeichnung das entlastete Doppelsitzventil ν v^ ist mit einer biegsamen Platte m verbunden, auf welche von einer Seite, und zwar in der \ Richtung der Pfeile //, der reducirte Druck einwirkt. Diese Platte erhält den entsprechenden Gegendruck von der anderen Seite, aber nicht, wie bei älteren bekannten Constructionen, durch eine Feder oder durch ein Gewicht, sondern durch eine gegen die Platte drückende Flüssigkeitssäule, z. B. eine Quecksilbersäule. Der dadurch erzielte Vortheil besteht darin, dafs die Platte von beiden Seiten auf ihrer ganzen Fläche gleichmäfsig belastet und infolge dessen nicht so der Abnutzung ausgesetzt wird.The throttling valve, in the drawing the relieved double-seat valve ν v ^, is connected to a flexible plate m , on which the reduced pressure acts from one side, namely in the direction of the arrows //. This plate receives the corresponding counter-pressure from the other side, but not, as in older known constructions, by a spring or a weight, but by a column of liquid pressing against the plate, e.g. B. a column of mercury. The advantage thus obtained is that the plate is loaded evenly on both sides over its entire surface and, as a result, is not so exposed to wear and tear.

In der Zeichnung ist angenommen worden, dafs der Druck ρ den Widerstand der Quecksilbersäule ganz überwunden und das Ventil υ ν ganz geschlossen hat. Zwischen dieser und der entgegengesetzten Stellung, in welcher sich die von dem Druck / ganz entlastete biegsame Platte gegen ein Sieb s s oder eine andere Begrenzung legt, welche den Druck durchläfs.t, befinden sich die den verschiedenen Graden der Drosselung entsprechenden Mittelstellungen der biegsamen Platte.In the drawing it has been assumed that the pressure ρ has completely overcome the resistance of the mercury column and the valve υ ν has completely closed. In which the of the pressure / completely relieved flexible plate ss between the latter and the opposite position against a screen or other boundary specifies which durchläfs.t the pressure, there are the various degrees of throttling of the corresponding intermediate positions of the flexible disk.
