Abstract

709,829. Sparking plugs. LUCAS (INDUSTRIES), Ltd., J. Oct. 2, 1952 [Oct. 5, 1951], No. 23208/51. Class 7(4) In a sparking plug of the kind adapted for the discharge to occur at a low voltage between a pair electrodes and across the intermediate surface of an insulator, one of the electrodes c being provided at the inner end of a stem b which is contained in the insulator a and the other electrode being in the form of a sleeve d which embraces the insulator a, there is provided an annular gas pocket g surrounding the sleeve d and having a restricted entrance h adjacent the discharge surface. The metal sleeve d either closely fits an annular shoulder e in the body or is integral with the latter; the entrance h is formed by a metal ring in the body or as shown by an annular shoulder i in one with the body. In a modification, the sleeve is shortened and the insulator is made to closely fit the shoulder whilst the opening into the gas pocket is through a gapped or perforated flange attached to the sleeve and secured in the body. The flow of gas into and out of the pocket keeps the spark gap clean.
