What is a traction gas spring?

A device that provides controlled tension without the use of external energy.
Traction gas springs produce controlled tension and are used in many components.
A traction gas spring usually helps lift an object, helping it return to its original position and remain in its final position.
What is the difference between a compression gas spring and a traction gas spring?
The starting position of the piston rod that pulls the gas spring is unloaded in the cylinder.
The piston rod speed of the standard traction gas spring cannot be adjusted and is specified as fast.
Sodemann's traction gas spring is not damped because the cylinder does not contain oil, but a special grease - used to lubricate the pressure seals.
The service life of a traction gas spring is about half that of a conventional gas spring with compression characteristics. Usually, the compressed gas spring is referred to as a "gas spring".
It is only when we look at the traction gas spring that we add a word for a specific property.
