Die Erfindung betrifft einen Acetylenentwickler derjenigen bekannten Gattung, bei welcher der Karbidbehälter über dem Wasserbehälter angeordnet ist und die Karbideinfall-Öffnung von einem ausdehnbaren Balg gesteuert wird. Siebezweckt, diese Art Acetylenentwickler für Fahrzeuge geeignet zu machen. ,Bei dieser Verwendung wird das Wasser leicht durch die Erschütterungen umher- und ausgespritzt.The invention relates to an acetylene developer of the known type in which the carbide container is arranged above the water container and the carbide inlet opening controlled by an expandable bellows. The purpose of the sieve is this type of acetylene generator to make it suitable for vehicles. , With this use, the water flows through easily the tremors splashed around and out.

ίο Um dies zu vermeiden, ist gemäß der Erfindung der Balg mit einem Karbidzuführungsrohr verbunden, welches beim Sinken des im Balg herrschenden Gasdruckes über einen an den Bewegungen des Balges nicht teilnehmenden Kolben so geführt wird, daß der Kolben die Karbideinfallöffnung erst freigibt, nachdem das Karbidzuführungsrohr in das Wasser eingetaucht ist, so daß das Karbid durch einen allseitig geschlossenen Schacht in das Wasser fällt.ίο To avoid this is according to the invention the bellows is connected to a carbide feed pipe which, when the gas pressure in the bellows drops, via a the movements of the bellows not participating piston is guided so that the piston only releases the carbide inlet opening after the carbide feed pipe is immersed in the water so that the carbide enters the water through a shaft that is closed on all sides falls.

Damit das Wasser bei angehobenem Karbidzuführungsrohr nicht umherspritzen kann, ist zAvischen der Wasseroberfläche und dem unteren Ende des Karbidzuführungsrohres eine an sich bekannte, geschlitzte, elastische Membran angeordnet; wenn sich das Karbidzuführungsrohr auf diese Membran senkt, drückt es die durch die Schlitzung entstandenen Lappen in das Wasser, so daß eine Art Tasche entsteht, auf deren Flächen das Karbid sanft in das Wasser hinuntergleitet. So that the water cannot splash around when the carbide supply pipe is raised zAvic the water surface and the lower end of the carbide feed pipe a per se known, slotted, elastic membrane arranged; when the carbide feed tube lowers on this membrane, it presses the rag created by the slit into the water, so that a kind of pocket is created on the surfaces of which the carbide slides gently down into the water.

Gemäß einer weiteren Ausführungsform der Erfindung erhält der Kolben, über welchen das Karbidzuführungsrohr geführt wird, zu diesem eine kurze, begrenzte Relativbewegung, vermöge welcher er beim Beginn des Zusammenziehens des Balges .,den Zeitpunkt der Eröffnung des Karbidzuführungsrohres verspätet; hierdurch wird erreicht, daß der im Balg herrschende Gasdruck mehr ausgenutzt werden kann, als es der Fall wäre, wenn der Kolben diese Bewegung nicht ausführte. Beim Beginn der. Aufwärtsbewegung dient die Relativbewegung dazu, um den oberen Teil des Karbidzuführungsrohres von etwaigem Kalkansatz zu reinigen.According to a further embodiment of the invention, the piston receives over which the carbide feed pipe is guided, a short, limited relative movement to it, by virtue of which it is at the beginning of the contraction of the bellows., the point in time the opening of the carbide feed tube delayed; this achieves that the gas pressure in the bellows can be used more than would be the case, if the piston did not make this movement. At the beginning of the. Upward movement the relative movement serves to move the upper part of the carbide feed tube from to clean any limescale deposits.

Die Erfindung ist in der Zeichnung dargestellt, und zwar zeigtThe invention is illustrated in the drawing, namely shows

Fig. ι eine für Fahrzeuge bestimmte Lampe im Aufriß;Fig. Ι a lamp intended for vehicles in elevation;

Fig. 2 einen Längsschnitt nach der Linie III-I1I der Fig. 1;FIG. 2 shows a longitudinal section along the line III-I1I of FIG. 1;

Fig. 3 die zwischen der Wasseroberfläche und dem unteren Ende des Karbidzuführungsrohres angeordnete elastische „ Membran im Grundriß.3 shows that between the water surface and the lower end of the carbide feed pipe arranged elastic "membrane in plan.

Über dem Wasserbehälter 1 ist der Karbidbehälter 2 angeordnet; beide sind durch Ringe 3, 4 abnehmbar miteinander verbunden. Der untere Teil des Karbidbehälters 2 ist bei 5 eingezogen, um den Gasraum zu verkleinern und der Lampe eine gefällige Form zu geben. In seinem oberen Teil besitzt der Karbidbehälter 2 eine Scheidewand 6, während der untere Teil gegen den Wasserbehälter ι durch einen kegelförmigen Boden 7 mit Flansch 8 abgeschlossen ist.The carbide container 2 is arranged above the water container 1; both are through Rings 3, 4 detachably connected to one another. The lower part of the carbide container 2 is moved in at 5 to reduce the gas space and give the lamp a pleasing shape admit. In its upper part, the carbide container 2 has a partition 6, while the lower part against the water tank ι through a conical bottom 7 with flange 8 is completed.

Der Karbidbehälter 2 ist durch einen Deckel 9 oben abgeschlossen. Auf der Scheidewand 6 liegt der ausdehnbare Balg 10; beide Teile sind durch einen Ring 11 mit Flansch 12,The carbide container 2 is closed at the top by a cover 9. On the septum 6 lies the expandable bellows 10; both parts are through a ring 11 with flange 12,

Claims

on which the housing 13 is screwed, connected to one another. A hollow rod 14 is connected to the cover of the bellows 10 and carries the carbide feed tube 16, 29 by means of the arms 15. The upper part 16 of the supply pipe is connected, close to its entrance opening 17, to a flexible sack 18 which is fastened at 19 to the flange 8 of the funnel 7. In the hollow rod 14, the rod 20 is loosely guided with collars 2011 of the piston 21 closing the entrance opening 17. The rod 20 has a finger 22 which passes through a slot 23 in the hollow rod 14 and lies between the stops 24 of the fixed housing 13. One end of a helical spring 25 surrounding the hollow rod is fastened to the upper end of the hollow rod 14, while the other end engages a fixed flange 26 which lies below the drawn-in point 27 of the housing 13. By the tension of the spring the bellows is usually held in the folded position and the piston 21 is thereby pressed so far downwards that it lies within the part 16 of the feed tube so that no carbide can collapse. In the opening of the water container 1 sits a tubular insert 30 which carries a membrane 31, known per se, provided with slits 32 (FIG. 3). The insert 30 is provided with a lateral opening 3ο3 through which the gas that has possibly accumulated above the water can escape into the gas space. The evolved gas is fed to a burner 33 (FIG. 1) through a pipe 34 which is connected to the carbide container 2 by a nut 35. Within the carbide space, the tube is surrounded by a filter 36; According to FIG. 1, the tube 34 consists of two parts which are united by a sleeve 34 ″ in order to be able to easily separate the connection when the carbide container is lifted from the water container. The screw 38 connected to the hollow rod 14 with nut 37 is used The housing 13 is perforated at the top and is surrounded by a filter 13 °, which is held at a certain distance by a ring 13 *. The working method of the developer is as follows 2.7 screwed so high (FIG. 2) that the bellows 10 can move freely, the spring 25 pulls the bellows 10 together so that the carbide feed tube moves downwards so far that its lower part 29 hits the membrane 31 During this movement the inlet opening 17 has left the piston 21, the piston rests with its finger 22 on the lower stop 24 and the inlet opening 17 is t free. The carbide falls into the water and gas begins to develop. As soon as the gas pressure overcomes the tension of the spring 25, the bellows 10 expands and the feed pipe 29 is raised. The incidence opening 17 first strikes the piston 21 and is closed by this. The piston 21 is raised until the finger 22 meets the upper stop 24, then the upper part 16 of the feed tube is guided over the piston until the arm 15 lying under the lower stop 24 hits this stop. As soon as the gas pressure drops, the finger 22 first lowers to the lower stop 24, whereby the piston 21 is fixed. This gives the piston 21 a lower position than it would assume if the movement relative to the hollow rod 14 did not take place. It releases the incidence opening 17 only after the feed pipe 29 has moved further downwards. Patent-A ν proverbs:
