Abstract
An actuating drive () including a ball screw drive () for activating a self-closing, linearly activated fitting () and a method of use are provided. While the opening of the fitting () with the actuating drive () takes place by an electric motor by the ball screw drive (), a restoring movement is transmitted to the spindle () when closing the automatically closing fitting (). The restoring movement, and thus also a closing movement of the fitting (), can be at least indirectly decelerated by way of the ball screw drive (), this being able to protect the fitting () and ultimately also the ball screw drive () and optionally further components connected to the fitting () and/or the ball screw drive () from damage, and facilitating a fail-safe function.
