  Einrichtung zur Dämpfung des Hochspannungsstromes von Zündvorrichtungen, insbesondere von   Magnetzündern.   



   Die Erfindung bezieht sich auf eine Einrichtung zur Dämpfung des Hoehspannungsstromes an Zündvorrichtungen, insbesondere an   Magnetzündern,   um einen grossen Elektrodenabbrand an der Kerze und   Ankerrückwirkung   am   Magnetzunder   zu vermeiden. Zu diesem Zweck hat man bisher entweder einen Kondensator oder einen Dämpfungswiderstand in den Hochspannungsstromkreis eingeschaltet. Der Kondensator hat den Nachteil, dass er zu   Rückzündungen   im Hochspannungskreis führt und dass er den abfallenden Lichtbogen nicht vollständig unterbindet. Der Dämpfungswiderstand hat den Nachteil, dass er den kapazitiven Funkenkopf des Zündfunkens schwächt und die Spitzenspannung an der Kerze herabsetzt.

   Zweck der Erfindung ist es nun, den Funkensehwanz des Zündfunkens an der Kerze zu unterdrücken, ohne den Funkenkopf zu schwächen und ohne die Spitzenspannung   herunterzuset7. en.

  Device for damping the high-voltage current from ignition devices, in particular magneto-igniters.



   The invention relates to a device for damping the high voltage current on ignition devices, in particular on magneto igniters, in order to avoid large electrode burn-off on the candle and armature reaction on the magneto-magneto. For this purpose, either a capacitor or a damping resistor has been switched into the high-voltage circuit. The capacitor has the disadvantage that it leads to reignitions in the high-voltage circuit and that it does not completely prevent the falling arc. The damping resistor has the disadvantage that it weakens the capacitive spark head of the ignition spark and lowers the peak voltage at the plug.

   The purpose of the invention is to suppress the spark tail of the ignition spark on the plug without weakening the spark head and without lowering the peak voltage7. en.
 EMI1.1
 an ohmic damping resistor is connected in parallel to this.



   In the drawing, the subject matter of the invention is a schematic picture of an ignition system
 EMI1.2
 In the circuit of the low-voltage winding there is a breaker c in the usual way. In the line from the high-voltage winding to the spark plugs! is a capacitor e and to this an ohmic resistor f connected in parallel.
 EMI1.3
 with a parallel resistor or a special capacitor with a resistor in front of each candle.



   The capacitor and the resistor can also be placed in the high-voltage circuit of the ignition device. By combining the capacitor with a damping resistor, both can be selected so that on the one hand the. Capacitor allows the spark head (capacitive part of the ignition spark) to pass through without weakening and, on the other hand, the resistance causes the spark tail (inductive part of the ignition spark) to die down quickly.



   PATENT CLAIMS:
1. A device for damping the high-voltage current from ignition devices, in particular magneto ignition devices with a capacitor in the high-voltage circuit, characterized in that an ohmic resistor is connected in parallel with the capacitor.
