Description
Es sind Atmungsvorrichtungen zum Eindringen in Räume mit nichtatembarer Atmo-■ sphäre bekannt, bei denen ein Sauerstoffbe-■' halter mitgeführt wird, außerdem aber Außenluft durch einen Schlauch zugeführt sind. Beide Quellen für Frischluft können abwechselnd gebraucht werden.There are breathing devices for entering rooms with a non-breathable atmosphere sphere known, in which an oxygen load- ■ ' holder is carried, but outside air is also supplied through a hose. Both sources of fresh air can be used alternately.
Die Erfindung besteht darin, einen Dreiwegehahn mit der Kupplung, durch die der ίο Schlauch für die Außenluft an die Vorrichtung angeschlossen ist, derartig zu verbinden, daß der Schlauch durch die Verstellung des Drei-, wegehahnes an- oder abgekuppelt wird.The invention consists in a three-way valve with the coupling through which the ίο Hose for the outside air to the device is connected to connect in such a way that the hose by adjusting the three, the way valve is connected or disconnected.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Fig. 1 ist eine Ansicht der Vorrichtung, Fig. 2 ein Querschnitt des Wechselhahnes, Fig. 3 ein Längsschnitt des Wechselhahnes. The drawing shows an embodiment of the invention. Fig. 1 is a view of the Device, FIG. 2 a cross section of the changeover tap, FIG. 3 a longitudinal section of the changeover tap.
Zu dem den Anschluß an die Atmungsao organe bildenden Teil a, der hier als Helm dargestellt ist, führt das Luftrohr b. Es enthält an seinem Ende einen Dreiwegehahn c, dessen einer Weg dauernd nach dem Luftrohr b geöffnet ist, während die beiden anderen abwechselnd geöffneten Wege nach der Sauerstoffzuleitung d und dem Luftschlauch e .'.': führen. Die Sauerstoffzuleitung d ist fest mit dem Dreiwegehahn c verschraubt und wird aus der Sauerstoffflasche f durch das Absperrventil g und das Druckminderventil h gespeist. Der Luftschlauch e ist durch eine lösbare Kupplung mit dem Dreiwegehahn c verbunden. Der an dem Luftschlauch e befestigte Teil i der Kupplung hat zwei seitliche Zapfen k, um die je ein Haken / greifen kann, der mit dem Kücken m des Dreiwegehahnes verbunden ist. . STo the connection to the Respiratory organs forming part a, which is shown here as a helmet, the air tube b leads. At its end it contains a three-way valve c, one of which is permanently open to the air tube b , while the other two alternately open paths lead to the oxygen supply line d and the air hose e . '.': The oxygen supply line d is firmly screwed to the three-way valve c and is fed from the oxygen bottle f through the shut-off valve g and the pressure reducing valve h. The air hose e is connected to the three-way valve c by a releasable coupling. The part i of the coupling which is attached to the air hose e has two lateral pins k, around which a hook / can grip each, which is connected to the cock m of the three-way valve. . S.
In der gezeichneten Stellung des Dreiwegehahnes ist die Sauerstoffzufuhr aus dem Rohr d abgesperrt und die Luftzufuhr durch das Rohr |« geöffnet. In dieser Stellung halten die Haken Il die Schlauchkupplung des Luftzuführungsschlauches β geschlossen. Wird der Luftschlauch β zum Hindernis für die freie Bewegung des Trägers der Vorrichtung oder hört die Luftzufuhr durch ihn auf, so wird dais Hahnkücken m gedreht, bis es an einen entsprechend angebrachten Anschlag anstößt. Dadurch wird zugleich die Sauerstoffzuleitung geöffnet und der Luftschlauch e abgekuppelt, so daß er herunterfällt. IIn the drawn position of the three-way valve, the oxygen supply from the pipe d is shut off and the air supply through the pipe | «is opened. In this position, the hooks II keep the hose coupling of the air supply hose β closed. If the air hose β becomes an obstacle to the free movement of the wearer of the device or if the air supply through it stops, then the cock plug m is turned until it hits a correspondingly attached stop. This simultaneously opens the oxygen supply line and disconnects the air hose e so that it falls down. I.
Der Träger der Vorrichtung kann alsdann ohne Gefährdung durch Luftmangel weiter vordringen, den Rückweg antreten oder auch die Einklemmung des Lnftschlauches e beseitigen, den Luftschlauch wieder ankuppeln und weiter arbeiten. ' .· i ■The wearer of the device can then advance further without the risk of a lack of air, start the way back or also eliminate the jamming of the air hose e , reconnect the air hose and continue working.
