Suspension system for motor vehicles as well as damping valve for said suspension system

摘要

A suspension system with at least one hydraulic spring strut. At least a portion of the hydraulic medium is displaced into a hydropneumatic spring reservoir during the compression movement of the spring strut, and that portion of the hydraulic medium flows back into the spring strut during the expansion movement. At least the expansion flow is conveyed through the flow path of a damping valve and damped due to the fact that the flow path is continuously closed and reopened in an alternating fashion by means of a valve element once a expansion flow is present. The valve element is bypassed via a bypass which is constructed in such a way that a pressure compensation between the sections of the flow path arranged on both sides of the valve element is ensured in the static condition in which essentially no flow is present; and that the bypass essentially loses this pressure compensation function in the dynamic condition in which a flow is present.
