The invention relates to a hydraulic transmission unit for an actuator, which hydraulic transmission unit can be filled with a hydraulic fluid and has a first and a second chamber which are hydraulically interconnected and of which one is designed as a drive chamber and the other one is designed as an output chamber. At least in the first chamber, a piston is arranged movably along a piston axis, such that this piston subdivides the first chamber into a variable-volume working chamber and a rear-side chamber, the rear-side chamber being delimited at least partially by a bellows element having a variable axial length. The invention further relates to an actuator having such a hydraulic transmission unit.

An assembly for preloading a cable rotary-pendulum kinematic system is provided. The assembly includes a rotational body of a cable rotary-pendulum kinematic system. The rotational body is configured to rotate about the longitudinal axis thereof and is immovable in the direction of the longitudinal axis. The assembly further includes at least one gas spring surrounding the rotational body and which may be compressed in the direction of the longitudinal axis. The assembly further includes primary cables, which force-lockingly connect the rotational body to the gas spring in such a way that a rotational motion of the rotational body causes compression of the gas spring, whereby the assembly is preloaded.

Various embodiments may include a coupling element for an electrical switching device comprising: a first switching contact at a first end of a winding body; a second switching contact; and a rotating body through which the winding body extends. The rotating body rotates on the winding body and the winding body translates along its longitudinal axis. A cord is arranged on each of the two sides of the rotating body between the rotating body and the winding body so that winding and unwinding of the cord is caused by opposite rotational movements of the rotating body driving a translational movement of the winding body. The rotating body is coupled to two springs so that a spring force always acts on the rotating body in both directions of rotation. A lock blocks the rotating body in at least two extreme positions of the translational movement of the winding body.
