Actuating device
First Claim
1. An actuating device for regulating a control mechanism subjected to a force against the direction of regulation, whereby the actuating device comprises:
- a drive shaft;
a rotating spindle spaced axially apart from and connected in a moveable manner to said drive shaft;
an actuating element adapted to be axially displaced by said rotating spindle in the direction of regulation;
at least two electric motors, each motor adapted to be actuated and controlled both individually and in co-operation, each of the at least two electric motors being capable of rotating said drive shaft in a feed direction; and
a housing adapted to receive the actuating device.

Abstract
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.
