ABSTRACT:
A drive system for a moveable wing, especially for a door or a window, is described. The drive system includes at least one energy storage device by whose discharge of energy the wing is moved. The energy storage device is hereby controllable in its energy discharge by means of a control system. The control system has an electrically controllable control element. The motion of the wing is directly or indirectly detected by a sensor, whose output signal is fed into a regulating device, which controls the control element. The regulating device is realized in a way, that the influence of the control element, dependent on the motion of the wing, can change the energy discharge of the energy storage device.
