FIELD: machine building.
SUBSTANCE: present invention relates to an actuator which actuates valves or vent flaps. Fail-safe actuator for movement of part between two end positions in each case has drive (18, 118), by means of which the first or second power train (24, 26) can be moved. Power transmissions (24, 26) in each case have their own output shaft (34, 38) and can be actuated independently of each other. Energy storage device is connected to the second output shaft (38) besides, the holding device selectively retains energy or releases it from the energy storage device so that the second output shaft (38) can be moved. Engagement of the first output shaft (34) in rotation ensures that in case of failure of drive (18) it moves to the specified end position. These two output shafts (34, 38) are driven by gear wheels (32, 36), if the power transmissions are actuated. Also described is an assembly consisting of an actuator and a movable part.
EFFECT: broader functional capabilities.
