A fluid pressure damping device in which the filling medium 4 is under high pressure comprises a cylinder 1, a piston 2 and a piston - rod 3 extending through a first wall of the cylinder. An end part 5 freely passes through a second wall of the cylinder and is provided with an annular flange 6 within the cylinder. An elastic sealing ring 9 is placed between the flange 6 and a corresponding annular surface of the second wall such that, in its uncompressed state, a gap is left between the cylinder and the outer surface of the sealing ring for filling the damping element with fluid. When the pressure is cut off externally of the damping device the internal pressure acts on the flange to compress the sealing ring against the annular surface of the cylinder. The construction may be incorporated in hydraulic, pneumatic or hydro-pneumatic damping devices. The filling may be an inert gas, e.g. nitrogen, at from 50 to 200 atmospheres. |
