Functional principle of gas struts

Gas springs are used wherever masses are pushed, lowered, pulled or positioned. Controlled travel speeds and damping properties can be set using various nozzles and oils. In contrast to conventional spiral springs, gas springs are characterized by a flat force line, which can be influenced by varying various factors.

  • Controlled travel speed
  • damping
  • maintenance-free construction detail
  • simple assembly
  • Flat spring characteristic curve
  • lockable
  • The gas strut essentially consists of a piston rod, seal and a pressurized cylinder tube. It thus represents a force accumulator. Nitrogen (N2) is used for filling and oil for lubrication. A physical property is used to push out the piston rod. Closed filling media spread out evenly in all directions under pressure. Gas can be compressed, but not oil.


    Due to the pressure filled in, there is overpressure in the sealed cylinder compared to the outside. Accordingly, the same gas pressure is present on both sides of the nozzle due to the nozzle bore. The piston rod surface, on which the gas pressure acts, remains as the effective contact surface.
