A hydraulic shock absorber comprising a shock absorber tube enclosing a hollow piston rod which moves in an oscillating manner corresponding to successive compression stages and rebound stages. The piston rod connects to a working piston that divides the interior of the shock absorber tube into two working areas. A bypass connects the two working areas of the shock absorber tube. The piston slide valve which is used to block and release the bypass is actuated by the pressure of a control pressure medium. The piston slide valve contains a piston slide which can be displaced by the control pressure medium against the force of a restoring spring, and which blocks or releases the bypass. The shock absorber is configured to be switched to a lower damping effect of the rebound stage by means of a controlled pressure application and without changing the damping effect of the compression stage.
