HAHN gas springs with the ballpoint pen principle are hydropneumatic, self-contained and maintenance-free adjustment elements. They are filled with compressed gas (nitrogen), which is used to provide the spring force. The spring force results from the internal pressure in the cylinder, which is generated by the filling medium nitrogen. With the gas spring, this pressure acts on the cross-sectional area of the piston rod. In the unloaded state, the piston rod is always extended. Pushing in the piston rod reduces the volume in the cylinder and the gas is compressed. This results in an increase in force (progression) of the gas spring depending on the diameter of the piston rod and the volume of the cylinder.
In addition, the gas spring can be mechanically locked in the pushed-in position using the principle of a ballpoint pen. Similar to the principle of a ballpoint pen, the lock can be released by gently pressing it in, after which the gas spring extends automatically. A large number of suitable connections and fittings ensure that the gas spring is optimally attached to your application.
