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 for opening and closing an electrical contact; a second switching contact; a push rod mounted to translate along a longitudinal axis; an actuator connected to the push rod causing the push rod to translate; a pulse mass element; and a spring element coupling the pulse mass element to the push rod. The first switching contact is connected to the push rod.

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.

In addition to liquid in a thermal volume-neutral stroke transmitter, first and/or second displacement body(ies) is/are positioned in the stroke transmitter, for displacing the liquid. These three materials in the closed system are designed so that the stroke transmitter remains pressure-free during temperature changes.

Thermally volume-neutral stroke transmitter, in particular for metering valve without hydraulic compensator

The hydraulic temperature compensator has at least one longitudinally extensible hydraulic chamber and a gas-filled chamber which is at least partly enclosed by the hydraulic chamber, wherein the hydraulic chamber is subdivided into a first sub-chamber and a second sub-chamber which are hydraulically connected to each other by at least one throttle point and wherein the second sub-chamber adjoins the gas-filled chamber. The stroke transmitter has at least the hydraulic temperature compensator, a stroke actuator acting on the temperature compensator, and a further hydraulic chamber which is fluidically connected to the first sub-chamber of the hydraulic chamber of the temperature compensator, wherein the further hydraulic chamber is in fluidic connection with a displaceably mounted actuating element.

A stroke translator or an injector having a solid-state actuator for generating a stroke and a hydraulic system for the hydraulic transmission of the stroke of the solid-state actuator to a control element such as a jet needle of a valve. The hydraulic system has hydraulic volumes hermetically sealed to the outside by metal bellows and constitute a hydraulic bearing with compensation for play. The advantages over known hydraulic levers are such that a complete metal seal is provided, and that a lower-wear design can be realized. Furthermore, a modular structure can be produced.

A pressure regulator can be used particularly in a CNG-operated motor vehicle as an electronically controlled pressure reducer for maintaining the gas pressure constant on the injection valve used for filling the respective cylinder. The pressure regulator is composed of a control unit (), a pressure reducer () that is controlled by the control unit (), and a throttle () which connects the gas outlets () of the working chamber () of the control unit () and the pressure reducer (). A piezoelectric actuator () which affects the valve () of an overflow device () makes it possible to specifically modify the gas pressure (P) in the working chamber () of the control unit () and simultaneously influence the position of the valve () of the overflow device () of the pressure reducer (), thus allowing the output pressure (Pout) of the pressure reducer () to be adjusted to a predefined desired value.
