A piston/damper tube assembly may include a damper tube with damping fluid, a movable piston rod, a working piston, a controllable 4-way bottom valve with a control member, and a compensation space. Two flow passage ways of the bottom valve connect the working space remote from the piston rod via the control member to the compensation space. Two control ways of the bottom valve load the control member on a first side with a pressure of the piston rod-side working space and on a second side with a pressure of the compensation space. The control member may control the flow passage ways in a manner dependent on the pressure of the piston-rod-side working space that prevails on the control member on the first side via a fluidic connection, and on the pressure of the compensation space that prevails on the control member on the second side via an opening.
