摘要： The invention relates to a pressure regulating valve (1) having a compression spring fixed in a valve housing for positioning a valve plunger (3) connected to a magnetic armature (4) in the position above a valve seat (2) and not electromagnetically excited, in order to create a connection between at least two pressure medium channels opening into the valve housing (1), and having a further compression spring disposed coaxially to the first compression spring in the valve housing (1), having the characteristic that the first compression spring is designed as a control spring (6) forming a stroke and force-specific spring drive by adjusting the spring rates of both compression springs to the force/distance curve of an electromagnet by varying the current in an exciter coil (10), wherein the further compression spring is designed as a variably adjustable spring (7) acting opposite to the control spring (6).

摘要： The invention relates to a proportional control valve for the variable hydraulic adjustment of the damping force of a shock absorber, for which purpose the proportional control valve has a throttle function which can be set by varying the strength I of the electric current. The invention provides that on the basis of an instantaneous level of the electrical current Iist the proportional control valve is first closed by increasing the current to a maximum current strength Imax for a short time period toverdrive in order to change the damping force F, and the proportional control valve is then opened again by reducing the current strength I to a defined average current strength I in which the proportional valve assumes an intermediate position which results in a volume flow Q which corresponds to the desired change in the damping force F.
