A method for switching over a solenoid valve having a movable valve body between a first position and a second position, wherein the method comprises at least the following method steps: a) adjusting a switching current to a pre-energization current intensity, in which the valve body remains in the present position, for a first time interval, and b) adjusting the switching current to a first switchover current intensity, which introduces a switchover movement of the valve body, for a second time interval.

Method for switching over a solenoid valve

A magnetic valve device includes a valve receiving device and a valve insert of a magnetic valve which is received in the valve receiving device. A high pressure resistance is obtained in one of the modes of embodiment. The magnetic valve device includes either a pressure mechanism configured to press the valve insert against the valve receiving element or a sealing element arranged in a notch in the valve insert or a sealing element arranged between an axial filter and the valve insert.

An electromagnetically actuatable valve for brake systems in motor vehicles, comprises a hydraulic part and an electric part. The valve is partially placed inside a valve block, in which an inlet borehole and an outlet borehole for a hydraulic fluid are made. The hydraulic part comprises a valve element inside of which a transversal borehole is made that communicates with the inlet borehole. In addition, a number of longitudinal boreholes, which are connected to the outlet borehole, are made in the valve element. The transversal borehole and the longitudinal boreholes are connected via a closing element. The valve enables a controlled opening and closing of the closing element thereby making a low-noise switching of the valve possible.

Method and apparatus for driving a solenoid valve

A hydraulic unit for wheel slip control, which is located between a master cylinder and wheel brake cylinders. Reflection damping devices are installed in main brake lines located between the hydraulic unit and the master cylinder which damp pressure waves that originate at control valves of the hydraulic unit. When the control valves are triggered in the wheel slip control mode the pressure waves are largely kept away from the master cylinder. By the means of length adaptation of the main brake lines, the brake lines can also contribute to the damping.
