Abstract
A hydropneumatic telescopic strut includes a shock absorber having a damper cylinder filled with an incompressible damper fluid, a damper piston displaceable in the damper cylinder, and a damper piston rod. A gas pressure spring has a spring cylinder filled with a compressible suspension fluid and a spring piston arranged such that the spring piston is displaceable in the spring cylinder. The shock absorber and the gas pressure spring are connected in parallel with one another and the shock absorber and the gas pressure spring are movable telescopically upon spring deflection and rebound of the telescopic strut. An equalization reservoir is connected with the damper cylinder such that the damper fluid is provided for volume equalization of a time-variable displacement of the damper fluid by the damper piston rod upon spring deflection and rebound of the telescopic strut.
