  • Valve piston arrangement for a vibration damper
    Patent number: 10415663
    Abstract: A valve piston arrangement for a vibration damper has an electrically controllable valve for regulating flow and a hydraulic valve unit, which includes at least one hydraulic valve and is hydraulically connected in series to the electrically controllable valve. The electrically controllable valve and the at least one hydraulic valve of the hydraulic valve unit are surrounded by a shared housing, which is provided for arrangement on a piston rod of the vibration damper. The housing forms at least one first opening for communication with a first working chamber of vibration damper and at least one second opening for communication with a second working chamber of vibration damper. A flow path between the at least one first opening and the at least one second opening is guided within the shared housing over the electrically controllable valve and the at least one hydraulic valve of the hydraulic valve unit.
