KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Dieses Druckminderventil dient zum Verringern des Druckes von hoch gespannten Gasen jeder Art und unterscheidet sich von den bis jetzt bekannten vortheilhaft dadurch, dafs die das Druckminderventil bethä'tigende Membran zugleich das Sicherheitsventil des Apparates bildet, sobald durch irgend eine nicht vorgesehene Ursache ein höherer Druck im Gehäuse des Apparates entsteht, als der durch Feder b und Druckschraube α eingestellte. Diese Anwendung der Membran bildet das Wesentliche der Erfindung und ist dieselbe vollständig unabhängig von der äufseren Form des Druckminderapparates.This pressure reducing valve is used to reduce the pressure of highly stressed gases of all kinds and differs from those known up to now advantageously in that the diaphragm acting on the pressure reducing valve also forms the safety valve of the apparatus as soon as a higher pressure in the device for some unforeseen cause The housing of the apparatus arises as the one set by spring b and pressure screw α . This application of the membrane forms the essence of the invention and is completely independent of the external shape of the pressure reducing device. Der zum Verringern des hochgespannten Gases dienende Apparat (Fig.i und 2) besteht aus einem pendelartig aufgehängten Hebel in Verbindung mit einer Membran, welche zu dem vorher erwähnten Zweck durchlocht ist.The apparatus used to reduce the high-tension gas (Fig.i and 2) consists from a pendulum-like lever in connection with a membrane, which to is perforated for the aforementioned purpose. S1 ist der bei S2 sich drehende Hebel, welcher bei O einen Hartgummikegel trägt und durch eine Schraubenmutter η in Verbindung mit einem Gummibuffer gegen den die Zuleitung r des Gases vermittelnden Ventilsitz ρ elastisch geprefst wird. S 1 is the lever rotating at S 2 , which carries a hard rubber cone at O and is pressed elastically by a screw nut η in conjunction with a rubber buffer against the valve seat ρ which mediates the supply line r of the gas. Während durch Feder b und Druckschraube a die Oeffnung bezw. Einstellung des Druckminderventils erfolgt, vermittelt die zum Zwecke der Dichtung bei m tellerartig geformte Schraube Jn1 die Verbindung des Hebels mit der Membran c. While b by spring, and a pressure screw, the opening BEZW. When the pressure reducing valve is set, the screw Jn 1, which is shaped like a plate for the purpose of sealing at m, connects the lever to the membrane c. Durch höheren Druck, als den durch Feder b eingestellten, wird die Membran c stärker nach aufsen gedrückt, während der Hebel mit der Schraube m nicht folgen kann, da er beim Ventilsitz ρ einen Anschlag findet. Die Dichtung wird dadurch bei m aufgehoben und das Gas entweicht durch die bei f durchlochte Membran nach aufsen.By higher pressure than that set by spring b , the membrane c is pushed outwards more strongly, while the lever with the screw m cannot follow, because it finds a stop at the valve seat ρ. The seal is thereby broken at m and the gas escapes outwards through the membrane perforated at f. Patεnt-Anspruch:Patent claim: Druckminderer mit Sicherheitsventil, dadurch gekennzeichnet, dafs eine in der Membran angeordnete Oeffnung bei zu starker Durchbiegung der Membran infolge hohen Druckes frei wird, bei dem vorgesehenen geminderten Druck aber durch das am Hebel S1 befestigte Ventil m. unter Wirkung der Feder b geschlossen bleibt.Pressure reducer with safety valve, characterized in that an opening arranged in the membrane is exposed if the membrane deflects too much as a result of high pressure, but remains closed at the intended reduced pressure by the valve m. Attached to the lever S 1 under the action of the spring b. Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.
