Der Pol 6'muss aus einem möglichst unverbrennbaren Stoffe von guter Leitungsfähigkeit bestehen, wie z. B. Platin, Iridium oder einer geeigneten Legierung. Zweckmässig wird der dünne Draht 6 in das Porzellan eingeführt, ehe dieses in den Brennofen gelangt, wodurch die Anwendung

Der Pol 6 kann um ein Geringes vor dem Isolationskörper vorragen, jedoch ist es zweck- mässig, ihn dicht an der Fläche des Körpers abzuschneiden, da in diesem Falle die freiliegende Fläche des Poles bis auf den Querschnitt des Drahtes verringert ist. Auch ergeben sich andere Vorteile bei dem glatten Abschneiden des Drahtes an der vorderen Fläche des Isolationskörpers, selbst wenn der Querschnitt ein grösserer ist. die doch nicht erzielt werden können, wenn der Pol vorragt,. Gcwülschtenfalls können auch beide Pole 6 und 3 im l soliermaterial eingebettet sein. Hindurch werden jede h die vorzuziehenden Wege verlassen, ohne dass ein besseres Er- gebnis zu erwarten ist.
Die in Fig. 2 gezeigte Ausführungsform unterscheidet sich von der erstbeschriebenen im wesentlichen nur dadurch, dass die kleine Öffnung 6'an Stelle des Pols 6 tritt. Das Ende der

result in a spark between the poles or between a pole and the surrounding short-circuit means. The spark was always enough to ignite the charge in the cylinder. The tests have further shown that no matter how weak the electric

Fig. 1 shows the longitudinal section of a spark generator manufactured according to the invention, and Fig. 2 shows the longitudinal section of a modified embodiment.
The spark generator consists of an insulation body A, which is suitably made of porcelain or another glass-like material and has a diametrical thickening that

held by a bushing / which is fin-screwed into the housing behind the thickening of the insulator. The insulating body serves to isolate the pole 6 from the pole 3 which is carried by the housing: 2.
The pole 6 'must consist of a material that is as incombustible as possible and has good conductivity, such as B. platinum, iridium or a suitable alloy. The thin wire 6 is expediently inserted into the porcelain before it gets into the furnace, whereby the application

breaking thin conductor 6 when the device is assembled.
The pole 6 can protrude slightly in front of the insulation body, but it is expedient to cut it off close to the surface of the body, since in this case the exposed surface of the pole is reduced to the cross section of the wire. There are also other advantages in the smooth cutting of the wire on the front surface of the insulating body, even if the cross section is larger. which cannot be achieved if the pole protrudes. If necessary, both poles 6 and 3 can also be embedded in the insulating material. As a result, every h will leave the preferable path without a better result being expected.
The embodiment shown in FIG. 2 differs from the first described essentially only in that the small opening 6 ′ takes the place of the pole 6. The end of
EMI2.6
both constructions are essentially the same.
