A shock absorber is disclosed consisting of a piston rod and a piston with damping valves, whereby parallel to the damping valves of the piston there is a bypass connecting the work chambers, and in the cavity of the piston rod there is an axially movable control rod to modify the cross section of the bypass. To create a simple and economical bypass adjustment device and a simple, easily interchangeable or adaptable adjustment device, the invention teaches that the control rod is actuated by a drive device, and with a longitudinal hole forms a seat valve.
