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.

Abstract: A hydraulic vibration damper having an inner tube arranged in a container; a piston arranged such that it is axially movable in the inner tube and the internal space of which is divided into a first working chamber and a second working chamber; a sealing element via which the piston rests against the inner tube in order to seal the first and second working chambers against one joining the first and second working chambers and arranged on the piston; and a bottom valve arranged on an axial end section of the inner tube in order to join the second working chamber to a compensation space formed between the container and the inner tube. The bottom valve projects axially into the second working chamber with a section. The piston has an operating position, in which same radially surrounds the section of the bottom valve projecting into the second working chamber.
