Abstract

1370762 Sparking plugs ROBERT BOSCH GmbH 7 Feb 1973 [8 Feb 1972] 6019/73 Heading F1B A sparking plug has an annular breathing space 20 formed between the earth electrode 17 and an insulator neck 12 and partially closed by the end of the earth electrode, the spark gap of the sparking plug consisting of a creeping-spark gap over the end 13 of the insulator neck and an air spark gap over an annular gap or clearance 23 between the end of the insulator neck and the earth electrode. The end of the insulator neck has a radial thickness of between 1À2 mm. and 3 mm. and the radial width of the annular gap or clearance is in the range of 0À16 mm. to 1 mm. The plug may comprise a control electrode 24 welded to the earth electrode 17. The central electrode 10 and the end 13 of the insulator neck may be flush.
