Abstract
Improvements in spark plugs with a central electrode composed of several parts and passing through an insulating body, forming one of the parts of the central electrode a disturbance regulating resistance and leaving the part of the electrode oriented towards the end of the hermetically closed ignition inside the insulating body. A powdered mass pressurized and secured against longitudinal displacements by means of a molten plug, characterized in that the inner end of the central electrode is passed on its side facing towards the tip both by a powder closing mass and also by a molten plug disposed next to the hermetic powder mass thereby establishing the conductive connection with the resistor.
