  "textContent": "A vibration damper with a damper piston which is arranged in a main tube with hydraulic medium and can be moved to and fro in an axial direction relative to the main tube. The main tube is arranged in a container tube, wherein an intermediate tube is arranged between the main tube and the container tube. The main tube, the intermediate tube and the container tube are arranged coaxially in a three-tube damper. The damper piston is attached at one end of a piston rod. The three-tube damper is equipped with a hydraulic end-position damping and at its end opposite the piston rod, has a central valve block with two damper valve devices. The central valve block is partially fitted with an air spring resting on an axial support ring which is connected by a single main weld seam to the container tube and central valve block by substance bonding.",
