| 摘要 |
The invention relates to an actuating device (1) for displacing a control device (3), against a force in the opposing direction (2) to the displacement, comprising an operating element (7) in a device housing (4), which may be axially displaced, at least in the direction of displacement by means of a feed mechanism (6). In order to improve said actuating device such that it may be simply operated without any impairment in emergency, when, for example the energy supply fails, or other problems occur, said actuating device comprises an emergency actuator, which may be externally operated and which may be connected to the feed mechanism (5) by means of a directional coupling device.
