Abstract
The invention relates to an actuating device, especially for use in a throttle device, comprising a turning spindle rotatably mounted in the device housing. Said turning spindle is functionally linked via a transmission device with a drive device to displace an actuating element that is linked with the turning spindle. The aim of the invention is to provide an improved actuating device that is secure and has a simple design and that can be telecontrolled in a simple manner without major maintenance work, without losses of functionality of the actuating device and at reduced costs. To this end, the actuating device comprises at least two separately or synchronously operated motors and the transmission device has at least one self-locking transmission unit, said transmission unit being functionally linked with the two motors for turning the turning spindle.
