AUTOMATIC VARIATION DEVICE OF THE GENERAL STEP, FOR MECHANICAL HELICOPTERS OF THE OSCILLATING BUSHING TYPE, to simplify piloting and increase flight safety, characterized by that, based on the principle of variation of the driving angle proportional to the variation of the torque engine, is performed mechanically by making the oscillating bushing receive a piece that places the blade in the space at the same time that the cardan rises, to allow the movements of the blade, both "abatement" and "drag".
