<p>The actuator (100) has a lever (110) with two ends (112, 114), and pivoted around a movable pivot (120), and elastic returning units e.g. spring (130), exerting return force (F1) to the end (112) of the lever under the effect of which, combined with a pivot reaction force (R). The lever applies actuating force to a rotative element (150) via the end (114). A pivot actuator (170) displaces the movable pivot with respect to the lever according to a received set point so that intensity of the actuating force is varied. An independent claim is also included for an element position controlling system comprising a sensor permitting periodically taking of a position of an end of a lever or actuated element.</p> |
