Abstract
A steering column comprises a pressure tube and a piston rod extending inwards and outwards of said pressure tube. The outer end of the piston rod is connected with a steering wheel. The pressure tube at its end remote from said steering wheel is connected with a steering mechanism of a motor vehicle. The pressure tube is rotatably mounted in a bearing tube. The piston rod is axially movable but non-rotatable with respect to the pressure tube. A liquid chamber is confined within the pressure tube and has a variable volume dependent on the axial position of the piston rod with respect to the pressure tube. The liquid chamber is connectable through a pivotal connection selectively with a pressure liquid source or with a pressure liquid receiving space or can be separated from both of them. A spring acts on the piston rod and is in balance with the liquid in the fluid chamber.
