Abstract (en)
The invention relates to a device for feeding oxidant to a combustion chamber (4) of a gas turbine comprising diaphragms (13-15) for regulating the flow of oxidant admitted, each diaphragm comprising a pivoting ring (15); the diaphragms are grouped in pairs; the rings (15) of two adjacent diaphragms each comprise a member (19) for regulating their pivoting; said members (19) for regulating the pivoting are connected (21) to a single control member (29). <??>According to the invention, the device for controlling the pivoting of the diaphragm comprises jacks (23) each comprising a working chamber (28) and a jack rod (29), the chambers of the different jacks being connected in parallel (40) to one and the same enclosure under pressure (41); the members for regulating the pivoting of two adjacent rings comprise, for each ring, a ball-joint housing (19) which is integral with said ring, a single ball-joint (21) being received in the housings of the two rings; and the ball-joint (21) is connected to said jack rod (29). <IMAGE>
