Abstract

827,944. Sparking plugs. CHAMPION SPARK PLUG CO. Jan. 28, 1958, No. 2794/58. Class 7(4) A sparking plug for gas turbine engines or jet engines comprises an inner sparking portion having spaced centre and shell electrodes 11, 13 disposed at an end extending into an engine combustion chamber and a heat shielding outer shell 2 surrounding and radially spaced from the inner portion over the length of the end extending into the combustion chamber, the outer shell having a portion 18 in contact with the inner portion when cool and which is moved away from the inner portion by thermal expansion when at normal operating temperatures and the outer shell having an opening 20 for admission of cooling air into the radial space 10 between the inner portion and the outer shell. As shown the central electrode 11 is electrically and physically connected to a body of semi-conductive material 12 but the semi-conductive body will be eliminated in certain types of igniters. Gas leakage around the semi-conductive body may be prevented by tamping masses of granular material 13, 14 in place in known manner. When the engine is at operating temperature cooling air exits largely through the space between the flanges 16 and 18
