An actuator device for producing a linear movement, has a hydraulic actuator which includes a first piston element for actuating the actuator and a second piston element for producing the linear movement. The piston elements are assigned respective fluidically coupled working chambers, the volumes of which can be changed by movement of the respective piston element. A piezoelectric actuator is provided for exerting a force on the first piston element.

Actuator device and method for setting a position of a linearly movable element

An actuating device for a vacuum switching tube has a connecting element which can be connected to an electric contact of the vacuum switching tube, an electromagnetic actuating device for displacing the connecting element between a first and a second position, and a retaining yoke, relative to which the connecting element can be displaced and has a first magnetic element. The first magnetic element generates a first and a second magnetic circuit in the retaining yoke. The actuating device further has a ferromagnetic retaining anchor, which is arranged on the connecting element. The retaining anchor is located in the first position of the connecting element in the first magnetic circuit and in the second position of the connecting element in the second magnetic circuit. The connecting element is held in the first and in the second position by a respective magnetic force between the retaining yoke and the retaining anchor.

Actuating apparatus for a vacuum interrupter and disconnecting arrangement

A simplified magnetic reluctance coupling for coupling a first shaft to a second shaft, has a hollow cylindrical stator which has at least one magnet that is/are distributed around the circumference of the stator. The reluctance coupling also has a first rotor, which is supported in such a way that it can rotate within the stator, is connected to a first shaft in a rotationally fixed manner, and has a plurality of ferromagnetic first portions distributed around the circumference thereof and spatially separated from one another, as well as a second rotor, which is supported in such a way that it can rotate within the first rotor, is connected to the second shaft in a rotationally fixed manner, and has a plurality of ferromagnetic second portions distributed around the circumference thereof.

Magnetic reluctance coupling having two rotors

A mechanical circuit breaker unit for interrupting a line includes a contact arrangement and an electromagnetic drive. The contact arrangement has first and second fixed contacts and a guided moving contact. The electromagnetic drive moves the moving contact. The separating unit can assume a first state and a second state. No electric connection exists between the first and second fixed contacts in the first state. The moving contact electrically connects the two fixed contacts to each other in the second state. The separating unit can be transferred from the second state into the first state by moving the moving contact. The second fixed contact has a recess for receiving the moving contact, and the moving contact engages at least partly into the recess when the separating unit is in the first state.

Separating unit with electromagnetic drive

A brake may include a bellows having an opening that leads into the interior of the bellows, a brake element joined to the bellows, a rotational element arranged at a distance from the brake element, a fluid reservoir or a pressure production unit, and a first conduit between the fluid reservoir or the pressure production unit and the opening.
