    • A valve device is formed with a through-channel and a field generating device. A fluid which can be influenced by a field is provided in the through-channel and the field generating device is configured to act on the field-influenced fluid in the through-channel by way of a field. At least one adjustment device is provided with which the field that is active in the through-channel can be adjusted. A portion of the cross-sectional area of the through-channel can be adjusted, the portion being exposed to a field of a specific intensity so that the through-channel can also only partly be exposed to a field of a specific intensity. Thus, the through-channel, as seen in the direction of the flow, can be divided into regions of different flow resistance, whereby characteristic curves, which were previously attained only with difficulty, are easily obtained when using the valve device in a damper, for example.
    • 阀装置形成有通道和场产生装置。 在通道中提供可以受场影响的流体,并且场产生装置被配置为通过场作用于通道中的场效应流体。 提供至少一个调节装置,可以调整在通道中有效的场。 可以调节通道的横截面积的一部分,该部分暴露于特定强度的场,使得通道也可以仅部分地暴露于特定强度的场。 因此,从流动方向观察的通道可以分为不同流动阻力的区域,由此在阻尼器中使用阀装置时容易获得先前难以获得的特性曲线, 例如。

    • The invention relates to a method for regulating the current flow of a coil that controls the viscosity of a magnetorheological fluid of a controllable energy absorber in a steering system for a motor vehicle, wherein during an accident the energy absorber acts as a hydraulic damper between two parts movable with respect to one another, whose damping force is determined by the current flow through the magnetic coil, wherein the following steps are provided: the relative velocity between a first part of the steering column movable with the steering wheel and a second part of the steering column fixed to the vehicle body is determined continuously or at intervals, the acceleration required for the braking from the measured relative velocity at standstill up to the end of the travel path is calculated, the current flow is calculated from the calculated acceleration in such a way that the value of the acceleration is approximately reached during the further travel of the parts movable with respect to one another.

    • A valve for magnetorheological fluids is formed with a control duct in which the magnetic field of a magnetic device, consisting of a permanent magnet and coil, acts on the fluid. The viscosity of the fluid is directly proportional to the magnetic field strength, with the result that the flow resistance of the valve can be varied via the coil current. The respective control duct is arranged in the end-face region of the coil and runs radially with respect to the center line of the valve, with the result that high flux densities can be achieved in the control duct. A permanent magnet is arranged in the inner space of the coil and, even under currentless operating conditions, can close the valve up to a certain blocking pressure.
    • 用于磁流变流体的阀门形成有控制管道,其中由永磁体和线圈组成的磁性装置的磁场作用在流体上。 流体的粘度与磁场强度成正比,从而可以通过线圈电流来改变阀的流动阻力。 相应的控制管道布置在线圈的端面区域中并相对于阀的中心线径向延伸,从而可以在控制管道中实现高的通量密度。 永久磁铁布置在线圈的内部空间中,并且即使在无电流操作条件下,也可以将阀关闭至一定的阻塞压力。
