Abstract
An actuator includes a screw mounted on a body to pivot, a nut connected to an element for moving, and that is engaged on the screw to be moved between an over-retracted first position and a deployed second position on either side of a retracted third position that is spaced apart from the over-retracted position by a distance corresponding to the screw rotating through a first angular sector and an anti-extension device comprising a friction disk having at least one smooth surface and an obstacle both for co-operating with at least one pawl, thereby defining both at least one second angular sector of free rotation for the friction disk and also a position for blocking the friction disk.
