Abstract

234,691. H³rner, M. L. Hofmann-. Sept. 26, 1924. Sparking - plugs. - An inwardly-widening cavity 6 is formed at the inner end of the plug; the end of the insulator is substantially flat and placed at the widest part of the cavity. The central electrode of the plug shown in Fig. 2 is reciprocated automatically by the varying cylinder pressures, and is formed with a collar 8 for rubbing against the casing attachment 4. Alternatively, the central rod may be fixed, and be surrounded bv a slidable sleeve on which the collar 8 is formed.
