摘要： An igniter assembly for a combustor of a gas turbine, the combustor being of a type including a case and a liner within said case, the assembly comprising an igniter including an elongate body having a first end, a second end, and a mounting feature intermediate said first and second ends, and the mounting feature includes a semi-hemispherical surface and an electrode extending through the body, and a base having an internal cavity with a first internal land, a second internal land opposite the first internal land, first seal A means in sealing contact with the first internal land, and biasing means, such as a spring, in contact with the second internal land and said mounting feature. The mounting feature is located within the cavity, the semi-hemispherical surface is proximate the first seal means, and the biasing means urges the semi-hemispherical surface into sealing contact with the first seal means to prevent the leakage of air therethrough.
