Abstract: A fluid damper comprises a housing having a working chamber, a damping fluid disposed in the working chamber, a piston unit arranged in the working chamber, the piston unit comprising a piston rod, a piston secured to the piston rod in such a way as to divide the working chamber in a first working chamber part and a second working chamber part, at least one flow duct interconnecting the first working chamber part and the second working chamber part, at least one bypass duct interconnecting the first working chamber part and the second working chamber part, an overload valve that blocks a fluid flow through the bypass duct in a blocking position and is arranged in a release position as soon as a minimum fluid pressure is reached, wherein in said release position, a fluid flow through the bypass duct is possible.

Abstract: A piston rod is guided with freedom of axial movement in a cylinder, where the position of the piston rod is detected by a first position-measuring device, which travels along with the piston rod, and by a second position-measuring device on the cylinder side. The two position-measuring devices are radially adjacent and axially parallel, and are supported in such a way that they cannot rotate with respect to each other.
