1. A system for controlling discharge doors of a turbomachine, the system comprising:
a ring; and
means for connecting the ring to each discharge door,
wherein the ring is formed by bars connected end to end by rotary connections ensuring that a pivoting of one bar induces a pivoting of the other bars, each discharge door being connected to a corresponding bar in order to open or close when the corresponding bar pivots, and
wherein the means for connecting the ring to each discharge door includes the corresponding bar connected to the corresponding discharge door by an arrangement comprising a lever with an end rigidly attached to the corresponding bar, and a connecting rod with a first end connected to the corresponding discharge door and a second end connected to the lever, the first and second ends of the connecting rod being connected to the corresponding discharge door and to the lever by pivot connections with axes parallel to the corresponding bar.
