System for controlling at least two variable-geometry equipments of a gas turbine engine, particularly by cam mechanism

A system for controlling at least two variable-geometry equipments of a gas turbine engine, the engine comprising at least a first core rotating at a first speed and a second core rotating at a second speed, the first equipment comprising at least one variable-pitch stator blade of a compressor of the first core moving between a closed position at idle speed and an open position at high speed, the second equipment comprising at least one compressor air bleed valve of the second engine core traveling between an open position at idle speed and a closed position at high speed, said system comprising:

• an actuator which actuates both equipments,
• wherein the actuator comprises at least one movable actuation member which actuates the variable-geometry equipments, and
• wherein the actuator comprises a cam mechanism, the cam being arranged to move means for transmitting movement connected to the variable-geometry equipments and actuate the variable-geometry equipments.
