Abstract

Bujía de incandescencia del tipo de espiga (10) para su disposición en el espacio de combustión de motores de combustión interna para compresión de aire, con una carcasa metálica (11) con forma tubular, en cuyo taladro longitudinal (12) está fijada herméticamente una espiga de incandescencia (16) con una parte de su longitud, encontrándose entre la espiga de incandescencia (16) y la carcasa (11) de la bujía por lo menos parcialmente una hendidura anular (21), que sale desde el extremo de la carcasa de la bujía en el lado del espacio de combustión, caracterizada porque la hendidura anular está formada por una zona (16C) con diámetro reducido en la espiga de incandescencia (16).Incandescent spark plug of the pin type (10) for its arrangement in the combustion space of internal combustion engines for air compression, with a tubular shaped metal casing (11), in whose longitudinal bore (12) a hermetically fixed glow plug (16) with a part of its length, being at least partially an annular groove (21) between the glow plug (16) and the spark plug housing (11), which emerges from the end of the housing of the spark plug on the side of the combustion space, characterized in that the annular groove is formed by an area (16C) with reduced diameter in the glow plug (16).
