ABSTRACT:
In a turbomachine in which the stator includes at least one stage of pivole blades and a ring which is movable axially to operate the levers which rotate the blades, the ring is moved by varying the pressure of gas which is contained in sealed chambers and which exerts a force between the movable ring and another fixed ring. This arrangement enables a better distribution of the forces to be achieved than purely mechanical movement control systems.
