The invention relates to a vibration damper (1) having a damper piston which can be moved back and forth in a main cylinder in an axial direction relative to the main cylinder by means of a hydraulic medium, the main cylinder being arranged in a container cylinder (5), an intermediate cylinder being arranged between the main cylinder and the container cylinder (5), the main cylinder, the intermediate cylinder and the container cylinder (5) are coaxially arranged in a three-cylinder damper (2), the damper piston is arranged at one end of the piston rod, and the three-cylinder damper (2) is equipped with a hydraulic end position damper and has a central valve block (12) with two damping valve devices (8, 9) at the end thereof facing away from the piston rod. In order to improve the vibration damper (1) in terms of function and/or manufacturing technology, the central valve block (12) is partially surrounded by an air spring which is supported on an axial support ring (15) which is connected to the container cylinder (5) and the central valve block (12) in a bonded manner by means of a single main weld, the three-cylinder damper (2) has a gas compensation volume at the piston rod-side end thereof, which gas compensation volume is arranged in the annular space between the intermediate cylinder and the container cylinder (5).
本发明涉及一种振动阻尼器(1),该振动阻尼器具有阻尼器活塞,阻尼器活塞在主筒中能够凭借液压介质沿相对于主筒的轴向方向来回移动,其中,主筒布置在容器筒(5)中,其中,在主筒与容器筒(5)之间布置有中间筒,其中,主筒、中间筒和容器筒(5)共轴地布置在三筒式阻尼器(2)中,其中,阻尼器活塞安置在活塞杆的一端,其中,三筒式阻尼器(2)配备有液压式端部位置阻尼件且在其背离活塞杆的端部处具有带两个阻尼阀装置(8、9)的中央阀块(12)。为了在功能和/或在制造技术方面改进振动阻尼器(1),中央阀块(12)部分地被空气弹簧环绕,空气弹簧支撑在轴向支撑环(15)上,轴向支撑环通过唯一的主焊缝材料配合地与容器筒(5)和中央阀块(12)相连接,其中,三筒式阻尼器(2)在其活塞杆侧的端部处具有气体补偿容积,气体补偿容积布置在中间筒与容器筒(5)之间的环形空间中。
