A controllable piston valve for a shock absorber in a piston cylinder structure includes a piston valve member controlling a throughflow area is actuated by a differential control piston. Oppositely directed effective surfaces of the control piston are subject to the pressure of the piston chamber and the annular chamber of the cylinder. The control piston and/or the piston valve member are additionally loaded with a pressure of a pressure source opposite to the larger of the effective surfaces, the pressure source being formed by a combination of a fluidic resistance and a fluidic capacitance and are supplied by the pressure in the piston chamber or the annular chamber of the piston cylinder structure.
