Abstract
A device for adjusting a foot point of a vehicle spring element includes a first wall element for connecting to a vehicle, a second wall element spaced from the first wall element and connecting to the spring element, and a chamber disposed between the first wall element and the second wall element for changing the distance between the first wall element and the second wall element by changing a volume of the chamber, the chamber having an incompressible fluid and the first and/or second wall element including a passage opening for the incompressible fluid to the chamber. In embodiments, the passage opening is fluidly connectable to a supply/discharge device for the incompressible fluid, and the chamber has a chamber wall with a third wall element extending from the first wall element to the second wall element, the mass of which is constant when the volume of the chamber is changed.
