Abstract
An adjustable damping valve for use on a hydraulic vibration damper, gas pressure damper or hydropneumatic suspension, which regulates the damping force, regardless of the orientation, and is variable in the regulation of the throughput, thereby providing a rapid switching frequency response. The damping valve has at least one electromagnet. In the preferred embodiment, each electromagnet can be controlled individually. Further, each electromagnet has a coil body with a winding and an armature. The armature is immersed in a fluid in the flow connection during operation. The armatures of the electromagnets interrupt and open directly the flow connection variably and quickly between an upper damping chamber of the vibration damper and a pressure equalization chamber. In one embodiment, there are a number of individual flow connections with corresponding electromagnets distributed over the circumference for fast action.
