Zündkerze für HeizgeräteSpark plug for heating devices

Die Brennkammern von Heizgeräten haben einen iiinlaßstutzen für das Brennstoff-Luft-Gemisch und außerdem einen ßlnschraubgewinde stutzen für eine Zündkerze. Bei Geräten mit kleiner Brennkammer ytlvü die Zündkerze thermisch so hoch beansprucht, daß der den Flammen ausgesetzte Isolator der Kerze gekühlt werden muß.The combustion chambers of heaters have an inlet connection for the fuel-air mixture and also a screw-in connection for a spark plug. For devices with small combustion chamber, the spark plug ytlvü thermally highly stressed so that the flame of the candle exposed insulator must be cooled.

Gemäß der Erfindung ist zu diesem Zweck der mit dem Einschraub·· gewinde versehene Schaft des Kerzengehäuses als Einlaßstutzen für das ßrennstoff-Luft-Gemisch ausgebildet, derart^, daß das Ge^ mls,ch radial in den nach der Brennkammer hin offenen Hohlraum des Schafts einströmt und an dem die Mittelelektrode tragenden Isolator entlang und an der Funkenstrecke vorbei in die Brennkammer gelangt.According to the invention, for this purpose the screw-in threaded shaft of the candle housing designed as an inlet port for the ßrennstoff-air mixture, such ^ that the Ge ^ mls, ch radially into the cavity of the open towards the combustion chamber Shaft flows in and passes along the insulator carrying the center electrode and past the spark gap into the combustion chamber.

Diese Führung des Brennstoff-Luft^Gemiechee hat noch den Vorteil, « daß sich an der Innenwandung des hohlen Schaftes Gemisch nieder« schlägt, das reicher' an Brennstoff und daher zUndwilliger ist als bei getrennt von der Zündkerze zugeführtem Brennetoff"Luft«Gemisqh, Sie hat außerdem auch noch konstruktive Vorteile durch den Wegfall eines besonderen Einlaßstutzens für das Brennstoff-Luft-Gemisch,This management of the fuel-air mixture has the advantage, " that mixture settles on the inner wall of the hollow shaft " suggests 'richer' in fuel and therefore more willing than with fuel "air" mixed in separately from the spark plug, It also has structural advantages due to the omission a special inlet connection for the fuel-air mixture,
