Abstract
An arrangement for operating shut-off members in gas turbine engines, particularly turbojet engines. Circumferential rotation of an actuating ring is converted into axial opening or closing movement by transmission element. These transmission elements are in the form of bellcranks which are pivotally supported in their elbow area on a fixed casing of the engine. A free arm end of each bellcrank is hinged to the actuating ring. Another free end of each bellcrank is hinged to a pull rod engaging at least one axially moveable shut-off member, or an axially adjustable shut-off element thereon. Two pull rods associated with respective shut-off members, are each pivotally connected on a side opposite the associated shut-off members at various points of an arm of the bellcrank. The arrangement is such that co-directional movement of the shut-off members produces different travels or strokes of the shut-off members.
