Abstract
An actuator (1) having an energy accumulator (6), with which an emergency drive (5) can be supplied, is configured to be tensioned by an electric motor (2). The motor (2) displaces at least one engaging element (41, 42) of the energy accumulator (6), on which a restoring force of the energy accumulator (6) acts, along an actuating travel in normal operating mode.

An actuating drive (1), comprising:
- a motor (2);
- an output (4) which is driveable by the motor (2) and is couplable to a fitting;
- an emergency drive (5) with an energy store (6), by which the output (4) is driveable as an alternative to the motor (2),
- the energy store (6) being a pneumatic energy store (7);
- the energy store (6) including a pressure chamber (8) with an expandable volume;
- wherein, during operation of the emergency drive, an expansion movement of the pressure chamber (8) is conducted to the output (4);
- and
- the energy store (6) is loaded by the motor (2) by actuation of the motor (2) against an end position of the actuating drive (1).
The actuating drive (1) as claimed claim 1, wherein the emergency drive (5) and the motor (2) are arranged in series in relation to the output (4), with the emergency drive (5) being arranged in a drive train between the motor (2) and the output (4), or the emergency drive (5) and the motor (2) are arranged in parallel in relation to the output (4).
