Abstract
An actuation device for adjusting a powered control device opposite the adjusting direction. The actuation device comprises an actuation element axially displaceable in a housing by a feed device at least in the adjusting direction. The actuation device includes an emergency actuation arrangement that may be actuated from outside the housing of the device. The emergency actuation arrangement is connected in motion with the feed device via a direction-switched coupling device. The feed device includes at least one motor for turning a rotating spindle. The at least one motor is rigidly connected with a rotating sleeve mounted capable of rotating in the housing and surrounding the rotating spindle. The rotating sleeve is capable of being set in a direction opposite the feed direction of the rotating spindle relative to the housing.
