Description

Die Erfindung betrifft ein Ausatmungsventil mit Rückschlag für Atmungsvorrichtungen zur. Rettung aus Erstickungsgefahr. Das Xeue besteht darin, daß der durch Federdruck geschlossene Ventilteller mit einer biegsamen Platte verbunden ist, die einesteils durch einen Kanal unter dem Druck der Ausatmungsluft, -andernteils durch Öffnungen des Ventildeckels unter gewöhnlichem LuftdruckThe invention relates to a non-return exhalation valve for breathing devices to the. Rescue from danger of suffocation. The Xeue is that the spring pressure closed valve disc is connected to a flexible plate, one part through a channel under the pressure of the exhaled air, -other part through openings of the Valve cover under normal air pressure

xo steht, während die Ausatmungsluft durch die vom Ventilteller überdeckte, mittlere Bohrung abzieht. Hierdurch wird der Flächendruck auf den Ventilsitz möglichst groß, ohne daß dadurch eine Erhöhung des Ausatmungs-Widerstandes herbeigeführt wird.xo stands while the exhaled air passes through the central hole covered by the valve disk withdraws. As a result, the surface pressure on the valve seat is as great as possible without that thereby an increase in the exhalation resistance is brought about.

Bei der in der Zeichnung im Schnitt dargestellten Ausführung· des Ausatmungsventiles ist die biegsame Platte α mit dem Ventilteller b zu einem einzigen Körper verschmolzen. welcher durch die Feder c gegen den Ventilsitz gedrückt wird. Sobald nun beim Ausatmen der Atniungsbeutel gefüllt und der entsprechende Überdruck erreicht ist, überwindet die durch die Öffnungd eintretende Ausatmungsluft mit Hilfe der biegsamen Platte α den Widerstand des federbelasteten Ventiltellers b und entweicht durch, die mit einem Siebe f versehene Ausgangsöftnung g. Verschwindet der Überdruck der Ausatmungsluft wieder, so wird das \"entil durch den Druck der auf den Ventilteller b wirkenden Feder c und den Gegendruck der durch die Öffnungen h ein- und ausströmenden Außenluft wieder geschlossen. Das Gesamtgewicht der bewegten Teile σ und b ist möglichst klein gehalten, damit die Unterschiede der Ventilbelastung in den verschiedenen Stellungen und Lagen des Ventiles so klein wie möglich ausfallen.In the embodiment of the exhalation valve shown in section in the drawing, the flexible plate α is fused with the valve disk b to form a single body. which is pressed against the valve seat by the spring c. As soon as the breathing bag is filled when exhaling and the corresponding overpressure is reached, the exhaled air entering through the opening d overcomes the resistance of the spring-loaded valve disk b with the help of the flexible plate α and escapes through the outlet opening g provided with a sieve f. If the overpressure of the exhaled air disappears again, the valve is closed again by the pressure of the spring c acting on the valve disk b and the counter pressure of the outside air flowing in and out through the openings h . The total weight of the moving parts σ and b is as close as possible kept small so that the differences in valve loading in the various positions and positions of the valve are as small as possible.
