Nozzle which comprises at least one convergent section, with a throat area A8 controlled by an actuation ring 4 which actuates a perimeter mechanism composed of a connecting rod 6, crank 8 and biarticulated bar 7 assembly per master lobe of the convergent branch. The crank 8 is joined by means of a ball-and-socket joint 8a to one of the ends of the corresponding biarticulated bar 7, the other end of this bar being joined, by means of a ball-and-socket joint 10, to an intermediate point of the shaft perpendicular to the root of the adjacent, convergent master lobe, this shaft coinciding with the articulation shaft 9 of the crank 8 of said adjacent lobe. <IMAGE>
