Description

Druckfeste, doppelwandige Lampenglocke. Verwendet man an sich bekannte doppelwandige Glocken, deren Mantelraum von einem Kühlmittel durchströmt wird, für Lichtquellen, die sich unter einem gegen die äußere Umgebung erhöhten Druck befinden, so entstehen in den Gefäßwänden durch die ungleiche Erwärmung Materialspannungen, die besonders bei der großen Stärke der druckfesten Wand leicht zu einem Zertrümmern des Gefäßes führen.Pressure-resistant, double-walled lamp bell. Is used per se known double-walled bells, whose shell space is traversed by a coolant, for Light sources that are under increased pressure in relation to the external environment, material tensions arise in the vessel walls due to the uneven heating, which, especially with the great thickness of the pressure-resistant wall, are easy to shatter of the vessel.

Um diese Gefahr zu vermeiden, wird gemäß der Erfindung die äußere Wand stark, die innere dünn ausgeführt. Jene hat die Aufgabe, der Druckdifferenz zwischen dem Innenraum und dem Außenraum standzuhalten. ' Beanspruchungen infolge von Temperaturdifferenzen entfallen auf die äußere Wand nicht. Die Innenwand dient lediglich dazu, eineu Abschluß des Kühlmittels gegen den Innenraum der Glocke herzustellen; damit der innere Mantel möglichst dinnwandig ausgeführt werden kann, wird das Kühlmittel unter annähernd dem gleichen Druck gehalten, wie er im Innenraum herrscht.In order to avoid this risk, according to the invention, the external Wall thick, the inner thin. That one has the task of the pressure difference to withstand between the interior and the exterior. '' Stresses as a result of of temperature differences do not apply to the outer wall. The inner wall serves only to produce a seal of the coolant against the interior of the bell; so that the inner jacket can be made as thin-walled as possible, the coolant kept under approximately the same pressure as is prevailing in the interior.

Um mit voller Sicherheit plötzlich auftretenden geringen Druckschwankungen, wie sie im ;Innenraum unvermeidlich sind, ihre gefährlichen Wirkungen zu rauben, wird erfindungsgemäß zwischen dem Innenraum des Gefäßes und dem vom Kühlmittel eingenommenen Raum ein nachgiebiges, elastisches Element geschaltet. Ein derartiges Element wird z. B. gebildet durch eine Membran oder durch eine Kapillare. Als Material für die Herstellung der Wände der Glocke kommen Glassorten im weiteren Sinne des Wortes in Betracht. Die Beschaffenheit und Zusammensetzung des Kühlmittels ist für die Erfindung belanglos; die Geschwindigkeit der Bewegung des Kühlmittels wird durch seine Wärmekapazität bestimmt. In vielen Fällen kann es zweckmäßig sein, die Kühlung des Innenmantels der druckfesten Wand als Zirkulationskühlung mit Rückkühlung durch die äußere Luft auszubilden. Diese Anordnung ergibt beispielsweise bei Bogenlampen eine einfache Konstruktion.In order to be able to with complete safety suddenly occurring small pressure fluctuations, how they are inevitable in the interior to rob their dangerous effects, is according to the invention between the interior of the vessel and that occupied by the coolant Space a flexible, elastic element switched. One such element is z. B. formed by a membrane or by a capillary. As material for the Making the walls of the bell come from types of glass in the broader sense of the word into consideration. The nature and composition of the coolant is important for the Invention irrelevant; the speed of movement of the coolant is made by determines its heat capacity. In many cases it can be useful to use cooling of the inner jacket of the pressure-resistant wall as circulation cooling with recooling to train the outside air. This arrangement results in arc lamps, for example a simple construction.
