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.

摘要： The invention relates to a closure device, especially one used to close channels guiding a pressure medium in a valve receiving body, comprising a rotationally symmetrical closure body (3) which is caulked in a receiving borehole (2) of a housing (11). The caulk point is embodied in the form of a ball (1), whereby the receiving borehole forms a funnel-shaped contraction in the direction of the closure body (3), said contraction overlapping with the periphery of the closure body (3) in a band-type region (4). A second housing stage (6) which is expanded in relation to a first housing stage (5) adjoins the caulk ball (1). Said second housing stage is formed as a result of plastic deformation of the housing material with respect to the funnel-shaped contraction of the receiving borehole (2).
