A system for the displacement of two thrust reversers for two jet engines of an airplane. Each thrust reverser has a drive motor operated by compressed air, a valve controlling the flow of compressed air to the motor, a set-point indicator including an input piston controllable by the action of compressed air, a differential transmission, and a feedback system from the motor to the differential transmission. The valve is actuated by the input piston and the motor via the differential transmission. The displacement of the two thrust reversers is halted by a system of stops acting on the input pistons at identical intermediate points in the paths of travel thereof and the displacement is thereafter continued after the thrust reversers have both reached their intermediate points in their paths of travel by deactivation of the stops.
