Description

Die bisher bekannten Zündkerzen weisen verschiedene Mängel auf, wie z. B. Verrußen, die Fehlzündungen und die Funkstörung. Um diese Nachteile beseitigen zu können, wurde eine Zündkerze in ihrem Aufbau grundlegend geändert, wie dieses in der beigefügten Zeichnung dargestellt ist.The previously known spark plugs have various shortcomings, such. B. Soot, the misfire and the radio interference. In order to be able to eliminate these disadvantages, a spark plug has been fundamentally changed in its structure, as shown in the accompanying drawing.

In den Kerzenkörper a wird die Mittelelektrode b, welche beinahe in ihrer ganzen Länge von einer Korundröhre c umgeben ist, mit einer Kupferbuchse d eingepresst. Zur weiteren Stabilisierung und Isolation wird in den oberen Hohlraum des Kerzenkörpers a der Sillimanitmantel e eingekittet. Die Masseelektrode f wird entweder, wie in der Zeichnung in Figur 2 dargestellt, über der Mittelelektrode b umgebogen oder von zwei Seiten in bekannter Weise durch den Kerzenkörper hindurchgesteckt.The center electrode b, which is surrounded by a corundum tube c for almost its entire length, is pressed into the plug body a with a copper bushing d. For further stabilization and insulation, the sillimanite casing e is cemented into the upper cavity of the candle body a. The ground electrode f is either bent over the center electrode b, as shown in the drawing in FIG. 2, or pushed through the plug body from two sides in a known manner.

Der Anschluß des Zündkabels erfolgt in bekannter Weise.The ignition cable is connected in a known manner.

Claims (3)

1. Zündkerze, dadurch gekennzeichnet, daß die in bekannter Weise an den oberen Enden mit Gewinde versehene Mittelelektrode (b) beinahe in ihrer ganzen Länge von einer Korundröhre (c) umgeben ist.1. Spark plug, characterized in that the central electrode (b), which is provided in a known manner at the upper ends with a thread, is surrounded by a corundum tube (c) for almost its entire length. 2. Zündkerze nach Anspruch 1), dadurch gekennzeichnet, daß die Mittelelektrode (b) mittels einer Kupferbuchse (d) zwischen Korundröhre (d) und Kerzenkörper (a) eingepresst ist.2. Spark plug according to claim 1), characterized in that the center electrode (b) is pressed in by means of a copper bushing (d) between the corundum tube (d) and the plug body (a). 3. Zündkerze nach Anspruch 1) und 2), dadurch gekennzeichnet, daß über der Kupferbuchse (d) der Mittelelektrode (b) ein Silimanitmantel (e) angeordnet ist, der der Kerze größere Festigkeit und bessere Isolation verleiht.3. Spark plug according to claim 1) and 2), characterized in that a Silimanitmantel (e) is arranged over the copper socket (d) of the center electrode (b), which gives the plug greater strength and better insulation.
