GUIDING OF A SPARK PLUG INTO A TURBINE ENGINE COMBUSTION CHAMBER

摘要

The infunnelion relates to the combustion chamber of a turbine engine, comprising at least one spark plug (11) borne by an outer casing and extending inside guiding means (14) borne by a rotating wall (3) of the chamber, said guiding means (14) including a tubular guide (16) traversed axially by the spark plug (11) and mounted with axial (j1) and transverse (j2) clearance on a funnel (15) secured to, and opening at, the rotating wall (3) of the chamber. In addition, the guide (16) comprises a flange ring (19) inserted with clearance (j1, j2) into an inner annular groove (20) in the funnel (15). The flange ring (19) is urged against a wall (24) of the groove (20) by an elastic member (25) mounted in the groove (20).
