An actuating device for regulating a control mechanism which is subject to a force against the direction of regulation. The actuating device includes a drive device which has a drive shaft and is connected in a moveable manner to a rotating spindle, by which means an actuating element can be axially displaced in the direction of regulation, in a housing receiving the device. The aim of the invention is to improve one such actuating device in such a way that actuation of the control mechanism is guaranteed in a constructively simple and cost-effective manner. In order to achieve this, the drive device comprises at least two electric motors which can respectively be actuated and controlled for the rotation of the drive shaft. |
