Abstract
A controllable vibration damper with damping force control may include a damper tube housing that is filled with damping medium. The controllable vibration damper may also include a damping valve element that is structurally and fluidically connected to the damper tube housing for damping force control. The damping valve element may be configured as a pilot-controlled pressure-limiting valve having a pilot valve. Further, a two-stage pre-throttle valve assembly placed in front of the pilot valve. The damping valve element may be arranged internally with respect to the damper tube housing in some cases. In other cases, the tamping valve element may be arranged externally with respect to the damper tube housing.
