The invention relates to an actuating device (1) for regulating a control mechanism which is subjected to a force against the direction of regulation (6). Said actuating device comprises a drive device (3) which has a drive shaft (2) and is connected in a moveable manner to a rotating spindle (4), by which means an actuating element (5) can be axially displaced in the direction of regulation (6), in a housing (7) 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 (3) comprises at least two electric motors (8, 9) which can respectively be actuated and controlled for the rotation of the drive shaft (2). |
