The gas spring is filled with non-toxic nitrogen under high pressure. This produces a charging pressure that acts on the cross-sectional area of the piston rod. This generates the extension force. If the extension force of the gas spring is higher than the force of the counterweight, the piston rod extends. If the extension force is lower, then the piston rod retracts. The flow cross-section in the damping system determines how quickly the extension occurs. In addition to nitrogen, there is a defined amount of oil in the interior for lubrication and end position damping. The suspension comfort of a pneumatic spring can be determined as needed and for the respective task.
