Abstract
A piston-cylinder unit configured to provide a level adjustment function based on internal pressure includes a working cylinder, a piston rod, a working piston mounted on the piston rod, and fastening elements coupled to the piston rod and the working cylinder. Each fastening element is configured to attach to a chassis or a vehicle body. One of the fastening elements is mountable with freedom of axial movement relative to the piston rod or the working cylinder and includes a cylindrical bore and a chamber disposed between the cylindrical bore and an end surface of the piston rod or a journal of the working cylinder. The end surface of the piston rod or the journal includes a first effective pressure-actuated cross-sectional area approximately the same as a second effective pressure-actuated cross-sectional area of the piston rod. The first and the second cross-sectional areas are actuated by system pressure.
