ABSTRACT:
An electrical igniter device for a gas turbine includes a conductive tubular shell having a spark electrode section and an integral body section with an open breach end and a conductive sleeve coaxial with the body section for coaxially supporting one end of a helical spring. Means are described for retractably supporting the shell, sleeve and spring within a protective cylinder wherein the pressure in the combustion chamber exceeds the force exerted by the spring.
