Abstract

A damping unit includes a cylinder which is filled with a damping fluid and in which a piston rod is guided, the piston rod associated with a bottom surface which has at least one axial through-hole which defines an effective flow cross section for the damping fluid; wherein the piston rod includes: a sleeve element which is fixed on the piston rod in the axial direction; a piston bottom element which is supported on the piston rod so as to be axially slidable and includes the bottom surface; a resilient element; and a termination element which is fixed on the piston rod in the axial direction and forms an indirect or direct stop for the piston bottom element in the insertion direction of the piston rod.
