GAS SPRING DEVICE

摘要

A gas spring device (10) is provided with a safe and effective way to reduce to zero the velocity of a piston rod (30) which is traveling at a high velocity in the gas spring device (10) during a failure of the gas spring device (10). This is achieved by stopping the piston rod (30) in a controlled manner through a stepwise reduction in its energy and velocity to keep the force on the piston (32) to a minimum at all times during the failure. The reduction in energy is caused by a plurality of frangible components associated with the gas spring device (10) which are designed to break during a failure, thereby dissipating the kinetic energy of the piston rod (30).
