Gas springs with hydraulic damping

The pressure tube of the gas spring with hydraulic damping is filled with gas and oil. When the piston rod is extended, the piston comes into contact with the oil on leaving the gas section and is dampened depending on the viscosity of the oil and the amount used.
Gas springs with hydraulic damping can be designed in accordance with the following principles:

  • gas spring dampened on extension extended (standard version)
  • gas spring dampened on compression (special version)
  • gas spring dampened on compression and extension (special version)
  • gas spring without damping (special versions)


Gas springs with hydraulic damping are installed in principle in the relevant flap with the piston rod pointing downwards. Despite the simple structure, this gas spring offers a wide range of design options.

In the case of a gas spring dampened on extension (standard version) the spring characteristics and the force level look as follows:
