Description

Die Erfindung betrifft eine Radioröhre, deren Glaskolben unter Zwischenlage eines Abdichtungsringes abnehmbar mit dem Sockel verbunden ist, in den ein mit dem Sockelsowie dem Kolbeninnern in Verbindung stehendes Glasröhrchen eingesetzt ist, das nach Evakuierung des Glaskolbens zugeschmolzen wird.The invention relates to a radio tube, the glass bulb with the interposition of a Sealing ring is detachably connected to the base, in the one with the base as well as the inside of the flask connected to the glass tube is inserted, which is melted shut after evacuation of the glass flask will.

Nach dem Erfindungsgedanken ist nun derAccording to the idea of the invention is now the

ίο Glaskolben unten mit einem rechtwinkligen Ringansatz versehen, der unter Zwischenlage des an sich bekannten Abdichtungsringes auf die obere, entsprechend breite Fläche des Sockels aufgesetzt ist, wodurch man eine ausreichend große Abdichtungsfläche erhält, so daß die Röhre auch bei längster Gebrauchsdauer ein einwandfreies Vakuum behält. Weiterhin ist nach dem Erfindungsgedanken zur Herausführung des Evakuierröhrchens aus dem Sockel eine von der Außenwand des Sockels aus in das Innere des Sockels führende waagerechte Bohrung vorgesehen, in die man ein ganz kurzes, horizontales Röhrchen einsetzen kann, wodurch die Lampe bei großer Betriebssicherheit billiger und das Ansetzen und Handhaben einer Evakuierungspumpe wesentlich einfacher wird.ίο glass bulb at the bottom with a right-angled Provided ring approach, with the interposition of the sealing ring known per se the upper, correspondingly wide surface of the base is placed, which gives a sufficient large sealing surface, so that the tube even with the longest period of use maintains a perfect vacuum. Furthermore, according to the idea of the invention, to lead out the evacuation tube is from the base a leading from the outer wall of the base into the interior of the base horizontal hole is provided, into which you can insert a very short, horizontal tube can use, making the lamp cheaper and the attachment with great operational reliability and handling an evacuation pump becomes much easier.

Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel veranschaulicht, und zwar zeigtIn the drawing, the invention is illustrated in an exemplary embodiment, namely shows

Fig. 2 eine Seitenansicht der zusammengesetzten neuen Radioröhre mit teilweisem Schnitt.Fig. 2 is a side view of the assembled new radio tube with partial Cut.

Im einzelnen besteht die Vorrichtung nun aus dem Kolben«, der unter Zwischenlage eines Gummiringes b o. dgl. auf den beispielsweise ebenfalls aus Glas bestehenden Sockel c aufgesetzt wird. In das seitliche Lochöi des Sockels wird nun beispielsweise zwecks Evakuierens des Inhaltes ein Glasröhrchen e eingekittet, an das die Vorrichtungen zum Auspumpen oder Aussaugen der Luft angeschlossen werden. Nach erfolgter Evakuierung wird dann das Röhrchen zugeschmolzen. In detail, the device now consists of the piston, which is placed on the base c, which is also made of glass, for example , with the interposition of a rubber ring b or the like. In the side hole of the base, for example, for the purpose of evacuating the contents, a glass tube e is cemented, to which the devices for pumping out or sucking out the air are connected. After the evacuation has taken place, the tube is then melted shut.

Die Wirkungsweise der Vorrichtung ist bereits in der Einleitung beschrieben und im übrigen aus der beiliegenden Zeichnung er- s° sichtlich.The operation of the device is already described in the introduction and in the rest can be seen in the accompanying drawing.
