  Rückzugs-und Warnsignal für Sauerstoffschutzgeräte. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 das Ventil immer nur für kurze Zeit geschlossen ist und die Hupe nur bei einer ganz bestimmten Druckgrenze in Tätigkeit tritt. 



   Schliesslich kommt der Ventilteller 6 mit dem Ventilsitz 61 in Berührung, wodurch die Hupe abermals als Warnsignal in Tätigkeit tritt und anzeigt, dass die Flasche leer ist. 



   Hat man vor der Benutzung des Gerätes vergessen, die Flasche zu öffnen, so bleibt der Membrankörper vollständig zusammengezogen, der Ventilteller 6 ruht auf dem Ventilsitz 61 und das Warnsignal ertönt so lange, bis die Flasche geöffnet wird. 



   PATENT-ANSPRÜCHE :
1. Rückzugs-und Warnsignal für Sauerstoffschutzgeräte, das durch eine unter dem Druck des Sauerstoffes stehende Membrane oder Membrankörper betätigt wird, dadurch gekennzeichnet, dass die Membrane oder der Membrankörper   (2)   mit einem Ventilkörper in Verbindung steht, auf dem zwei Ventilteller (5,   6)   angeordnet sind, die sich bei sinkendem Flaschendruck nacheinander auf ihre Ventilsitze (51,   61)   legen, wodurch jedesmal ein Signal in Tätigkeit gesetzt wird.

  Withdrawal and warning signal for oxygen protection devices.
 EMI1.1
 

 <Desc / Clms Page number 2>

 the valve is only closed for a short time and the horn only comes into action at a specific pressure limit



   Finally, the valve disk 6 comes into contact with the valve seat 61, whereby the horn again comes into operation as a warning signal and indicates that the bottle is empty.



   If you have forgotten to open the bottle before using the device, the membrane body remains completely contracted, the valve disk 6 rests on the valve seat 61 and the warning signal sounds until the bottle is opened.



   PATENT CLAIMS:
1. Withdrawal and warning signal for oxygen protection devices, which is actuated by a membrane or membrane body under pressure from the oxygen, characterized in that the membrane or membrane body (2) is connected to a valve body on which two valve plates (5, 6) are arranged, which lie one after the other on their valve seats (51, 61) when the cylinder pressure drops, whereby a signal is activated each time.

Claims (1)

2. Rückzugs-und Warnsignal nach Anspruch 1, dadurch gekennzeichnet, dass die Membrane oder der Membrankörper (2) unter dem Druck einer Feder (3) steht, die dem Sauerstoffdruck ent- EMI2.1 als auch bei 0 at, also wenn die Flasche leer oder nicht geöffnet ist, einer der Ventilteller (5, 6) sich auf seinen Sitz legt, wodurch die Atemluft gezwungen wird, durch das Signal, z. B. eine Pfeife, hindurchzuströmen. EMI2.2 2. withdrawal and warning signal according to claim 1, characterized in that the diaphragm or the diaphragm body (2) is under the pressure of a spring (3) which is generated by the oxygen pressure. EMI2.1 as well as at 0 at, so when the bottle is empty or not open, one of the valve plates (5, 6) lies on its seat, whereby the breathing air is forced by the signal, z. B. a pipe to flow through. EMI2.2
