Guide for the piston rod of a piston-cylinder assembly, especially for a vibration damper, a shock-absorbing strut, or a level-control element, where the guide body holds the cylinder tube and the outside tube and simultaneously centers the piston rod in a central bore. The guide body has two axially spaced sealing elements which rest on the outside surface of the piston rod and seal off the interior space of the piston-cylinder assembly from the atmosphere. A flow connection, starting from the area of the intermediate space between the seals, extends to the interior space and is provided with a nonreturn valve, through which a flow can proceed only in the direction of the interior space.
