Fig. ι und 2 zeigen im Schnitt das Sicherheitsventil in Ruhe und in Thätigkeit. Fig. 3 zeigt dasselbe mit abgenommenem Obertheil in Ansicht.Fig. Ι and 2 show in section the safety valve at rest and in action. Fig. 3 shows the same in view with the upper part removed. Der Untertheil A ist mit einem Zuleitungsstutzen α und einer nach innen gerichteten, düsenförmig ausgebildeten centralen Ableitung b ausgestattet und durch eine vom Obertheil B gehaltene Membran c geschlossen, hinter welcher eine unter Federdruck stehende Platte d angeordnet ist. Die den Gegendruck ausübende Feder f wird durch eine das Federgehäuse abschliefsende Mutter e auf den erforderlichen Druck gespannt.The lower part A is equipped with a feed pipe α and an inwardly directed, nozzle-shaped central discharge line b and is closed by a membrane c held by the upper part B , behind which a spring-loaded plate d is arranged. The spring f exerting the counterpressure is tensioned to the required pressure by a nut e closing the spring housing. Um ein unbefugtes Nachstellen zu verhüten, ist der röhrenartige Ansatz des Oberlheils B durch eine Ueberwurfmutter g geschlossen. Der Druck der Feder f 'richtet sich auf den verhältnifsmäfsig geringen Querschnitt der Auslafsdüse i>, während der Gasdruck auf die verhältnifsmäfsig grofse Ringfläche der Membran c wirkt.In order to prevent unauthorized readjustment, the tubular extension of the upper part B is closed by a union nut g. The pressure of the spring f 'is directed towards the comparatively small cross-section of the outlet nozzle i>, while the gas pressure acts on the comparatively large annular surface of the membrane c. Hieraus geht hervor, dafs selbst, wenn der Gasdruck nahezu die erlaubte Grenze erreicht hat, innen noch ein dichter Abschlufs der' Auslafsöffnung stattfindet, weil der Druck der Feder f direct gegen die Auslafsöffnung wirkt. Ist der erlaubte Gasdruck aber überschritten, so erfolgt umgekehrt ein plötzliches Oeffnen des Sicherheitsventils, indem der Gasdruck, auf die verhältnifsmäfsig grofse Ringflüche der Membran wirkend, ein Sichfestsetzen der Membran auf dem Rande der Ausflufsöffnung verhindert. ·From this it follows that even when the gas pressure has almost reached the permissible limit, there is still a tight seal on the inside of the outlet opening, because the pressure of the spring f acts directly against the outlet opening. Conversely, if the permitted gas pressure is exceeded, the safety valve opens suddenly, in that the gas pressure, acting on the relatively large annular curbs of the membrane, prevents the membrane from sticking to the edge of the outflow opening. · Pa tent-An spruch:Patent claim: Ein Sicherheitsventil an Druckkesseln für den Bierausschank, dadurch gekennzeichnet, dafs eine innerhalb des Gehäuses (A) central angeordnete Auslafsdüse (b) durch eine unter Federdruck stehende -Membran (c) geschlossen gehalten wird, deren, dem Gasdruck ausgesetzte Ringfläche gegenüber dem Querschnitt der Ausströmungsöffnung verhältnifsmäfsig grofs gehalten ist, zum Zweck, jederzeit einen dichten Abschlufs der Austrittsöffnung zu ermöglichen, aber auch beim Ueberschreiten des zulassigen Gasdruckes ein plötzliches Oeffnert des Auslasses zu bewirken. "A safety valve on pressure vessels for serving beer, characterized in that an outlet nozzle (b) located centrally within the housing (A) is kept closed by a spring-loaded membrane (c) whose annular surface exposed to gas pressure is opposite the cross-section of the outlet opening is kept relatively large, for the purpose of enabling a tight closure of the outlet opening at any time, but also to cause a sudden opening of the outlet when the permissible gas pressure is exceeded.
