Zusammenfassung:	The apparatus has a rotor (8) i.e. flywheel, moved over a drive motor e.g. electromotor, in a rotating movement, and a spring accumulator (6) arranged over a releasable grip in a frictional engagement that is stretched by the rotor. A setting piston (4) is driven over the accumulator in a setting direction. A frictional clutch is arranged downstream of the rotor to connect the rotor and the setting piston. The drive motor is operated in a normal operation mode through a set of sequential driving processes without changing direction of rotation of the drive motor. The spring accumulator is selected from a group consisting of a gas spring such as pretensioned gas spring, and helical spring such as steel spring or carbon fiber spring.
