Abstract

258,666. Napoli, M. de. June 25, 1925. Sparking-plugs. - Artificial quartz or similar material 3 possessing a small coefficient of expansion is moulded in position in the casing 1 which is formed with ribs 4 to obtain a better union. The insulation is hollow being closed at its outer end by a stopper 7, and the central conductor 8 is so placed that the sparkgap is substantially in alignment with the bore 5.
