ABSTRACT:
A gas spring comprises a cylindrical casing, in which a piston rod is guided for displacement concentric of a central longitudinal axis. A damping piston is mounted on the piston rod, dividing the interior of the casing into two sectional casing chambers. A filling of compressed gas is provided inside the casing. A damping device is provided for velocity-dependent damping of a motion of stroke of the damping piston and another damping device is provided for path-dependent damping of a motion of stroke of the damping piston. The result is a gas spring of excellently controllable stroke behaviour.
