Abstract
The piston with a valve for a hydraulic damper tube, comprises a piston body (116) having a fluid passage (112) interacting with a floating valve element (115) for controlling in both directions the amount of fluid flowing through the passage. The floating valve element includes a spring washer (115), the deflection (f) of which in the free state is between approximately 0.1 times and approximately 2 times the thickness (e) of the washer.
