 Gases und zur Verbindung einzelner Teile der   Vorrichtung     untereinander. Durch das Rohr   steht die Einrichtung in Verbindung mit einem Manometer p und einem Sicherheitsventile o sowie mit dem Regulierventile k, von dem ein Rohr l mit einem Gasausgleich beutel m abzweigt. 



   Die   Wirkupgb'. vise   dieser eimichtung ist folgende :
Nach   Verschliessung   der Füllschraube c entwickelt sich über dem im Behälter   a   befindlichen   @üssigen Sauerstoff   ein geringer Überdruck, dessen Stand auüerhalb am Manometer p abzulesen st. Unter der Voraussetzung, dass das Reglerventil k ein wenig geöffnet ist, steigt dann die   tt igkeit   in dem Steingerohr d aufwärts und   durchfliesst   bei teilweiser Verdampfung die Rohr- spirale e, welche in den Verdampfer f mündet, wobei die Flüssigkeit in die Verdampfer-

 darin erwärmend, nach dem Reglerventil k und von da aus durch das Rohr l nach dem Entnahmestutzen r.

   Dieser nimmt den Gasausgleichbeutel m und die Schlauchleitung auf, welche die Sauerstoffgase nach den Atmungsorganen bzw. der Verwendungsstelle führt. Wird der Zeiger des Reglerventiles k beispielsweise auf die Entnahmeziffer 5 (Liter) eingestellt, so gibt die Vorrichtung in einer Höhe von etwa 6000 m über der Erdoberfläche das verzeichnete Quantum Gas pro Minute, also in diesem Falle 5   1,   ab. Gelangt die Vorrichtung in einer Höhe von etwa   WOO 111   über der Erde, so wird, ohne dass irgend welche Regelung nötig ist, das für diese Höhe benötigte Quantum, gleich etwa 3 l pro Minute, abgegeben. 



   Falls ein übermässiger   Druck über der flüssigen Luft   im Behälter a entsteht, tritt das   Sicherheitsventil   o in Wirkung und bläst ab. 



   Das erfundene Verfahren kann überall da verwendet werden, wo eine sich dem   äusseren  
Arbeitsdtucke genau anpassende Druckgaserzeugung in entsprechender   Höhe des Druckes h'' <      selbsttätiger Wirkung gewünscht wird.   



   PATENT-ANSPRÜCHE :   l.   Verfahren zur Abgabe von Sauerstoff oder sauerstoffhaltigen Gasen, insbesondere für Atmungszwecke, in wechselnden Druckhöhen der Atmosphäre, dadruch gekennzeichnet, dass der verminderte bzw. der erhöhte äussere Druck. unter welchem die Gase verarbeitet bzw. ein-    geat, met   werden sollen, benutzt wird, um mit Hilfe der Einstellung eines vorteilhaft am äussersten Ende der Vorrichtung befindlichen Regler- oder Reduzierventiles mehr oder minder grosse Saut-   stossmengen aus füssigem   oder komprimiertem Sauerstoff selbsttätig entsprechend dem Wechsel   desDruckes bzw..dem erhöhten   oder vermindetten Gasverbrauch zu entnehmen, wodurch sich dieser Verbrauch in sparsamer Weise regelt.

 Gas and for connecting individual parts of the device to one another. Through the pipe the device is in connection with a pressure gauge p and a safety valve o as well as with the regulating valve k, from which a pipe l branches off with a gas equalization bag m.



   The effect. The vision of this equipment is as follows:
After the filling screw c has been closed, a slight overpressure develops over the liquid oxygen in the container a, the level of which can be read on the pressure gauge p outside. Provided that the regulator valve k is opened a little, the activity in the stone pipe d then rises and, with partial evaporation, flows through the pipe spiral e, which opens into the evaporator f, whereby the liquid enters the evaporator

 heating in it, after the regulator valve k and from there through the pipe l to the extraction nozzle r.

   This takes the gas compensation bag m and the hose line, which leads the oxygen gases to the respiratory system or the point of use. If the pointer of the regulator valve k is set, for example, to the withdrawal number 5 (liters), the device emits the recorded quantity of gas per minute, in this case 5 liters, at an altitude of about 6000 m above the earth's surface. If the device reaches a height of about WOO 111 above the earth, the quantity required for this height, equal to about 3 liters per minute, is delivered without any regulation being necessary.



   If there is excessive pressure above the liquid air in the container a, the safety valve o takes effect and blows off.



   The invented method can be used wherever one looks outward
Working pressure exactly matching compressed gas generation at the corresponding level of the pressure h '' <automatic effect is desired.



   PATENT CLAIMS: l. Process for the delivery of oxygen or oxygen-containing gases, in particular for respiratory purposes, at changing pressure levels in the atmosphere, characterized in that the reduced or increased external pressure. under which the gases are to be processed or inhaled or inhaled, is used to automatically generate more or less large amounts of liquid or compressed oxygen according to the setting of a regulator or reducing valve located at the extreme end of the device Change in pressure or the increased or decreased gas consumption, whereby this consumption is regulated in an economical manner.
