The damping valve for a vibration damper has a flow passage (9) in a piston (3) which is closed by a valve plate (5) biased by a plate spring (7). A second passage (29) can be connected to the first when a valve (25) opens. This consists of a valve plate (23) biased by a spring (27) fitted between it and the plate (5) of the first valve.
