Hydro-pneumatic vibration damper with alterable damping force

摘要

A cylinder (3) between a piston rod (1) guide and base valve contains a piston (2) possessing at least one valve and connected to a piston rod. The piston divides the interior of the cylinder filled with damping fluid into a piston rod side operating (4) space, and an underneath working space (5). A container (7) enclosing the cylinder with radial space between them forms a compensating space (8) filled with damping fluid and gas and to which the bottom working space is connected hydraulically by a base valve. (10). The entire electromagnetic valve arrangement (11) between the cylinder interior and the equalising space is positioned on the side of the base valve opposite the cylinder.
