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 Ifor a short time period tin 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.

A diaphragm-type accumulator for a slip-controlled vehicle brake system has a media-separating element in a housing bore including a diaphragm made of an elastic material, which has a concave design with respect to a pressure fluid inlet for the purpose of pressure fluid intake. The diaphragm is acted upon indirectly by an accumulator spring, with a diaphragm plate interposed, and wherein the diaphragm plate has a concave design with respect to the pressure fluid inlet.
