ABSTRACT:
A control device makes it possible to rapidly shift the bleed valves of an aircraft turbojet engine to a large opening position when the engine is under low power operation in order to prevent flame-out. The device allows for instantaneously interrupting the action of a control return cable when the valves are open from a certain given value. The device includes a drive support integral with a crank handle, in order to bring about the translation of the return cable, when the latter is not blocked by a translation stop member. The control device is used for opening of bleed valves of turbojet engines having two concentric annular jets.
