Description

Zündkerze, insbesondere mit Quarzisolierung Die Erfindung betrifft eine Verbesserung der Zündkerze, insbesondere mit Quarzisolierung, nach Patent 464843 und will durch eine besondere Anordnung und Ausbildung des in dem Kerzenkörper befestigten, das konische Quarzrohr umgebenden Glimmerpakets das Herausnehmen und Wiedereinsetzen desselben sowie seine Befestigung unter Druck erleichtern.Spark plug, in particular with quartz insulation. The invention relates to an improvement of the spark plug, especially with quartz insulation, according to patent 464843 and wants by a special arrangement and design of the fixed in the candle body, The mica packet surrounding the conical quartz tube allows removal and reinsertion facilitate the same as well as its fastening under pressure.

Es sind Zündkerzen bekannt, bei denen die Befestigung des Isolators durch eine in einem Einschraubstöpsel befestigte konische Glimmerschicht ausgeführt ist. Solche Ausführungen haben aber den Nachteil, daß durch die Druckbeanspruchungen während des Betriebs die konische Glimmerschicht nicht genügend Halt findet und in der Druckrichtung hierdurch verschoben wird, was zu mancherlei Störungen Veranlassung geben kann. Durch die vorliegende Erfindung soll nun dadurch Abhilfe geschaffen werden, daß eine Verschiebung des Glimmerpakets in der Druckrichtung unmöglich gemacht wird.There are known spark plugs in which the attachment of the insulator carried out by a conical mica layer fastened in a screw-in plug is. However, such designs have the disadvantage that the compressive stresses the conical mica layer does not have sufficient hold during operation and is thereby shifted in the direction of pressure, which gives rise to various disturbances can give. The present invention is intended to provide a remedy that a displacement of the mica packet in the printing direction is made impossible will.

In der Zeichnung ist ein Ausführungsbeispiel im Längsschnitt dargestellt.In the drawing, an embodiment is shown in longitudinal section.

Es ist i die innere Elektrode und m das dieselbe lose umgebende Quarzrohr, das am äußeren Ende durch eine Mutter b unter Zwischenlage eines Spannringes c auf der Elektrode i befestigt ist und am inneren Ende sich gegen Glimmerscheiben l abstützt.It is i the inner electrode and m the loosely surrounding quartz tube, which is fastened to the electrode i at the outer end by a nut b with a clamping ring c in between and is supported against mica washers l at the inner end.

Das das Quarzrohr in umgebende, mit Druck in den Kerzenkörper einzusetzende Glimmerpaket f ist auch am Außenumfang konisch gestaltet und von unten in eine innen entsprechend konisch gestaltete Büchse i mit Außengewinde eingesetzt, die in den Kerzenkörper g eingeschraubt ist. Die Büchse i besitzt am inneren Ende einen Rand 2, der ebenso wie der am oberen Ende der Büchse befindliche Rand 2 nach dem Einsetzen des Glimmerpakets nach innen umgebogen wird und so das Paket unter Druck hält.The mica packet f, which surrounds the quartz tube and is to be inserted into the candle body with pressure, is also designed conically on the outer circumference and inserted from below into an internally correspondingly conical sleeve i with an external thread, which is screwed into the candle body g. The sleeve i has at the inner end an edge 2 which, like the edge 2 located at the upper end of the sleeve, is bent inward after the insertion of the mica packet and thus keeps the packet under pressure.

Zündkerzen mit zweiteiligem Kerzenkörper sind an sich bekannt.Spark plugs with a two-part plug body are known per se.
