Vibration damper having two adjustable damping valve devices

Abstract

The disclosure relates to a vibration damper comprising two adjustable damping valve devices, wherein a damping valve device is connected to a piston-rod-side working chamber via a fluid connection and a damping valve device is connected to a working chamber spaced apart from a piston rod within a cylinder filled with damping medium. A fluid connection between the damping valve device and the working chamber occurs via at least one tube element. Both adjustable damping valve devices are connected to a common balancing chamber for receiving the damping medium displaced out of the working chambers by the piston rod. A line block is connected to the cylinder, which forms a first fluid connection to the damping valve device for one of the working chambers and forms an intermediate tube, encasing the cylinder, for a second fluid connection to the damping valve device for the other of the two working chambers. The second fluid connection is also connected to the line block. Both fluid connections have a separate radial channel within the line block, each being connected to an inlet opening of the damping valve devices. A reducer part is arranged between the cylinder and the first fluid line of the line block, and the second fluid line runs within the line block within a projection surface of the cylinder.
