Description

Es sind Gefäße für verflüssigte Gase, z. B. für verflüssigten Sauerstoff für Atemsdl#titzgeräte, bekannt, die doppelwandig ausgeb-i-I#d-et sind. Dabeiist der Zwischenraum zwischen -der Doppelwand evakuiert. Derartige wärmeisoTierende Gefäße haben den Nachteil, daß bei einer Speicherung des verflüssigten Gases unter Druck das Gas dürch die innere Wand diffu-ndiert, so daß das Vakuum zwischen den Doppefwänden nach und nach abfällt und demzufolge, die Wärmeisolation nachläßt.There are vessels for liquefied gases, e.g. B. for liquefied oxygen for breathing apparatus, known, which are double-walled designed-i-I # d-et. Is there the space between the double wall evacuated. Such heat insulators Vessels have the disadvantage that when the liquefied gas is stored under Pressure diffuses the gas through the inner wall, leaving the vacuum between the Double walls gradually fall off and, as a result, the thermal insulation decreases.

Die Erfindung vermeidet die- Nachteile'-.,. Sie betrifft ein Gefäß für verflüssigte Gase, ins-besondere flüssigen Sauerstoff, mit einem dbppelwandigen Mantel" dessen Zwischenraum evakuiert ist. Die Erfindungbesteht darin, daß innerhalb des IsoIi-ergefäßes ein druckfestes, Gefäß angeorühet ist. Die neue Vorrichtung hat den Vorteil',- daß ein -d'ruckfestes Aufbewahrungsgefäß geschaffen wird, dessen Wä:rmeisalatio-n stets die gleiche bleibt. Die Druckfestigkeit und die Wärmeisolation werden gleichsam verteilt. Soweit durch die Wan&ing des druckfesten Behälters Gase diffundieren, gefangen- diese in den Zwischenraum zwischen diesen drüdd-esten Behälter und, der inneren Wandung des Isolafionsgerätes. Dieser Zwischenraum kann ebenfaJ1s evakuiert sein. Er kann aber auch mit atmosphärischer Luft Normalen Druckes angefüllt und verschlossen sein. Bei einer einfachen, Ausführungsform steht der Zwischenraum mit der Außenluft in offener oder durch ein. Ventil abgeschlössener Verbindung, so daß die eich sammelnden Gase z. B. ü,ber das- Ven#ti#l'Ode-r unge!hindert ins Freie entweichen können.The invention avoids the disadvantages -.,. It relates to a vessel for liquefied gases, in particular liquid oxygen, with a double-walled jacket whose space is evacuated. The invention consists in the fact that a pressure-resistant vessel is attached inside the insulating vessel. that a pressure-resistant storage vessel is created, the heat of which always remains the same. The pressure resistance and the heat insulation are distributed as it were. As far as gases diffuse through the wall of the pressure-resistant container, they are trapped in the space between them. This space can also be evacuated. It can, however, also be filled and closed with atmospheric air at normal pressure. In a simple embodiment, the space with the outside air is open or closed by a valve Connection, so that the gases collecting calibration e.g. via the valve l'Ode-r unge! prevents you from escaping into the open.

In der Zeichnung ist eine Ausführungsform der neuen Voriirhtung im Schnitt dargestellt.In the drawing is an embodiment of the new Voriirhtung im Section shown.

Das Wärmeisolation3gefäß wird, aus den beiden kugelförmig-en Gefäßen i und 2 gebildet, deren Zwischenraum in an zich bekannter Art evakuiert ist. Innerhalb des Gefäßes 2 Viegt ein druckfester Behälter 4, der zur Aufnahme des verflüssigten Gases ' - wie z. B. verflüss-igten Sauerstoffs, dient. Steht das verflüssigte Gas im Gefäß unter Überdruck, so diffundiert es.,durch die Wandungen dieses Gefäßes in mehr oder minder geringen Mengen in den -Ho41-rau-m zwischen dem druckfesten Behälter 4 und dem Grefäß 2. Dieser Hohlraum steht mit der Außenluft am Hals des Gefäßes in offener Verbindung, demzufolge ka-nn sich in diesem Hohlraum ein Merdruck nicht ausbilden. Die Wandung des Gefäßes 2 bleibt dTuckunbe-lastet, so daß eine Diffusion durch diese Wandung nicht stattfindet.The thermal insulation vessel is formed from the two spherical vessels 1 and 2, the space between which is evacuated in a manner known per se. Inside the vessel 2 Viegt a pressure-tight container 4, which is used to hold the liquefied gas ' - such. B. liquefied oxygen is used. If the liquefied gas in the vessel is under overpressure, it diffuses through the walls of this vessel in more or less small quantities into the -Ho41-rau-m between the pressure-tight container 4 and the Grefäß 2. This cavity is exposed to the outside air Neck of the vessel in open connection, as a result of which a pressure cannot develop in this cavity. The wall of the vessel 2 remains unloaded, so that diffusion through this wall does not take place.
