KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Gegenstand der Erfindung betrifft eine Zündkerze für Explosionskraftmaschinen, bei welcher der Contactstift gegen die Metallhülse durch zwei Hohlkegel aus Isolirmaterial isolirt ist. Diese Isolirung unterscheidet sich von ähnlichen Isolirungen dadurch, dafs die inneren spitzen Enden der Hohlkegel fest in· bezw. über einander greifen.The subject matter of the invention relates to a spark plug for explosion engines which the contact pin isolates from the metal sleeve by two hollow cones made of insulating material is. This insulation differs from similar insulations in that the inner ones pointed ends of the hollow cones firmly in · or. grab each other.
Auf der Zeichnung ■· ist diese Isolirung der Zündkerze veranschaulicht.This insulation of the spark plug is illustrated in the drawing.
Der centrale Contactstift α wird hierbei mittelst zweier Druckkegel b und c in der Metallhülse d festgehalten, wobei zwischen die Druckkegel und die Hülse die beiden Isolirhohlkegel f und g eingeschoben sind. Zieht man die Muttern des Contactstiftes α an, so werden die Druckkegel b und c und damit auch die Isolirhohlkegel f und g mit ihren entsprechend ausgebildeten Spitzen axial verschoben. Die Isolirhohlkegel greifen dabei fest mit ihren Spitzen in einander. Dadurch wird der Contactstift α auch im Innern der Zündkerze in seiner ganzen Länge lediglich durch die beiden Isolirhohlkegel isolirt und gleichzeitig ein überaus fester Aufbau der Zündkerze erreicht.The central contact pin α is held in place in the metal sleeve d by means of two pressure cones b and c , the two hollow insulating cones f and g being inserted between the pressure cone and the sleeve. Taking α nuts of the contact pin, so the pressure cone b and c and thus also the Isolirhohlkegel f and g with their correspondingly formed peaks displaced axially. The hollow cones of the Isolirhohlkegel grip firmly into one another with their tips. Thereby, the contact pin is also insulated in the interior of the spark plug in its entire length only by the two Isolirhohlkegel while achieving a very solid construction of the spark plug α.
Den Isolirhohlkegel/ läfst man zweckmäfsig auf der dem Explosionsraum zugekehrten Seite etwas hervorstehen, so dafs zwischen den Polen α und h der Funkenstrecke eine Scheidewand gebildet wird, welche ein Ueberspringen von Funken aufserhalb der eigentlichen Funkenstrecke verhindert.The hollow insulating cone / is expediently made to protrude somewhat on the side facing the explosion space, so that a partition is formed between the poles α and h of the spark gap, which prevents sparks from jumping over outside the actual spark gap.
. Um einen Stromübergang auch an der nach aufsen gekehrten Seite der Zündkerze auszuschliefsen, ist es vortheilhaft, eine Isolirscheibe i zwischen den Druckkegeln und den Anzugsmuttern anzuordnen. . In order to exclude a current transfer also on the outward facing side of the spark plug, it is advantageous to arrange an insulating washer i between the pressure cones and the tightening nuts.
Als Material zur Herstellung der Isolirkegel können mit Vortheil aufgerollte Glimmerblätter Anwendung finden.Rolled up mica sheets can be used with advantage as the material for the production of the insulating cones Find application.
