Patent ID: 8690520

Claim:
A system for controlling at least two variable geometry equipment items of a gas turbine engine, the engine including at least one first body rotating at a first speed and a second body rotating at a second speed, the first equipment item being a variable-angle stator vane stage of a compressor of the first body moving between a closed position when idling and an open position at high speed, the second equipment item being at least one discharge valve of a compressor of the second body moving between an open position when idling and a closed position at high speed, the system comprising: an actuator that actuates both equipment items, and that comprises a disk that rotates about an axis linked to the equipment items by a mechanical transmission means comprising a pin that travels along a guiding track, a profile of the track defining actuation laws of the two equipment items when the disk is driven in rotation about its axis by the actuator.
