Abstract
A control mechanism for a machine element of the type including a fixed part and a movable part movable between two limit positions, e.g. an automotive vehicle clutch. A spring biasses the movable part to one of its limit positions. The control mechanism comprises a linkage for controlling the displacement of the movable part between its limit positions. A motor drives the linkage, and a resilient device is coupled to the linkage for reducing the force applied by the motor for displacing the movable part between its limit positions.
