Description

Vorrichtung zur Erzeugung von atembarer Luft. In den bisher bekannten Vorrichtungen verdampft die flüssige Luft .mehr oder weniger gleichmäßig, und es fehlt die Möglichkeit, die fortschreitende Verdampfung der flüssigen Luft zu verhindern für den Fall, daß die Entnahme von Atmungsgasen nicht erforderlich ist, oder sie in dem Augenblick einsetzen zu lassen, wo die Verdampfung gewünscht wird.Device for generating breathable air. In the previously known Devices evaporates the liquid air .more or less evenly, and it there is no possibility of preventing the progressive evaporation of the liquid air in the event that the withdrawal of breathing gases is not required, or they to start at the moment when evaporation is desired.

Da derartige Apparate demnach sofort nach ihrer Füllung, also ehe sie in Betrieb genommen werden können, erhebliche Verluste an verdampfender flüssiger Luft haben, hat die vorgeschlagene Vorrichtung bzw. Einrichtung den Vorteil, nur während der Zeit der Benutzung flüssige Luft in dampfförmigen Zustand überzuführen. Hieraus ergibt. sich eine bedeutend größere Gebrauchsfähigkeit. .Since such devices are therefore immediately after their filling, i.e. before They can be put into operation, considerable losses of evaporating liquid Have air, the proposed device or device has the advantage of only to convert liquid air into a vaporous state during the period of use. From this it follows. a significantly greater usability. .

Eine beliebige Regulierfähigkeit der Menge verdampfender flüssiger Luft ist bisher noch nicht vorgeschlagen worden. Für die Ausführungsmöglichkeit vorliegender Erfindung ist die Aufbewahrung der flüssigen Luft in einem absoluten Vakuum in einem gegen Wärme geschützten Behälter sehr vorteilhaft. Auf der Zeichnung ist ein Ausführungsbeispel veranschaulicht.Any ability to regulate the amount of evaporating liquid Air has not yet been proposed. For the possibility of execution The present invention is the storage of liquid air in an absolute Vacuum in a container protected from heat is very advantageous. On the drawing an exemplary embodiment is illustrated.

Die in einem Gefäß a (Hochvakuumflasche) gegen unbeabsichtigte Verdampfung durch einen Außenbehälter b .geschützte Menge flüssiger Luft wird in dem Augenblicke der Verwendung vergaster flüssiger Luft durch einen eingeführten Stab i zum Verdampfen gezwungen. Durch das Rohr k steigt infolge des über der Flüssigkeit sich bildenden Druckes -eine geringe Menge flüssiger Luft empor und spritzt in den ersten Vergaser d aus. Die sich bildenden Dämpfe und die eventuell mitgerissene Flüssigkeit werden in den zweiten Vergaser d und eventuell in einen dritten geleitet. .The in a vessel a (high vacuum bottle) against unintentional evaporation amount of liquid air protected by an external container b. is at the moment the use of gasified liquid air by an inserted rod i for evaporation forced. Through the pipe k rises as a result of the forming above the liquid Pressure - a small amount of liquid air rises and squirts into the first carburetor d from. The vapors that are formed and any liquid that may be entrained into the second carburetor d and possibly into a third. .

Von dem zweiten Vergaser d steigt die Luft weiter durch Rohrschlangen h o. dgl. bis zu dem Druckregler. V, wo ihr auf diesem möglichst langen Wege eine große Berührungsfläche mit der warmen Außenluft gewährleistet wird. Von dem Druckregler v steigt die von Flüssigkeit vollständig befreite und auf genügende Wärme gebrachte gasförmige Luft in bekannter Weise durch einen Schlauch m zu der Gasmaske u des Verbrauchers: ' Die vorliegende Erfindung -besteht im wesentlichen darin, daß durch Vermehrung oder Verminderung des über der Flüssigkeit stehenden Druckes ein Mehr oder Weniger an Flüssigkeit in den Vergaser d und damit zur Atmungsmaske u gebracht wird. Wird nun bei Inbetriebsetzung der Flasche diese mittels der Verschraubung g abgeschlossen, so entweicht der entstehende Überdruck durch das Rohr e hindurch bis zum Ventilsitz f. An dieses Ventil, welches in Ruhestellung offen steht, ist das Rohr e und e1 angeordnet. Drosselt man das Ventil f etwas, so beginnt der Druck auf die Flüssigkeit zu drücken uni bringt einen entsprechenden Teil derselben, durch das Rohr k aufsteigend in den Vergaser d. Wird die Drosselung stärker, so steigt eine entsprechend größere Menge im Rohr k auf; wird das Ventil gänzlich geschlossen, so erreicht der Apparat seine höchste Leistungsfähigkeit. Um einen gefährlichen Überdruck abzuleiten, können an geeigneten Stellen Sicherheitsventile p, p angebracht werden. Zweckmäßig ist auch die Vereinigung der Atmungseinrichtung mit einem Dewar-Heylandt=Gefäß, um durch diese Kombination die Gebrauchsfähigkeit und Betriebsbereitschaft bedeutend zu fördern. Ein Zeiger z ermöglicht ein Einstellen des Ventils nach der Skala s. Das Vakuum wird mit einem Absorptionsmittel o gebildet und erhalten.From the second carburetor d the air rises further through pipe coils h or the like to the pressure regulator. V, where you are guaranteed a large contact area with the warm outside air on this longest possible path. From the pressure regulator v, the gaseous air, completely freed of liquid and brought to sufficient heat, rises in a known manner through a hose m to the gas mask u of the consumer: The present invention consists essentially in the fact that by increasing or reducing the amount above the liquid standing pressure a more or less liquid is brought into the carburetor d and thus to the breathing mask u. If the bottle is now closed by means of the screw connection g when the bottle is put into operation, the resulting overpressure escapes through the pipe e to the valve seat f. The pipes e and e1 are arranged on this valve, which is open in the rest position. If the valve f is throttled somewhat, the pressure begins to press the liquid and brings a corresponding part of it, ascending through the pipe k, into the carburetor d. If the throttling becomes greater, a correspondingly larger amount rises in the pipe k; if the valve is completely closed, the apparatus reaches its maximum efficiency. Safety valves p, p can be installed at suitable points in order to divert dangerous overpressure. It is also advisable to combine the breathing device with a Dewar-Heylandt = vessel in order to significantly promote usability and operational readiness through this combination. A pointer z enables the valve to be adjusted according to the scale s. The vacuum is created and maintained with an absorbent o.
