Gas springs and dampers for industrial applications
Gas springs and dampers for
industrial applications
For decades now, STABILUS gas springs
have been well known for their successful
use in the automobile industry.
Since the early 1960’s, STABILUS
products have also been used in the
furniture industry, notably for applications
in swivel chairs.
Today, the gas spring has become a
practical design element in more than
100 different applications.
Compact design, high level of operating
convenience and safety in use are some.
Operating principle of a gas
spring
The gas spring is a hydropneumatic
adjusting element, consisting of a
pressure tube with a connecting fitting,
a piston rod with piston system and a
piston rod connection fitting.
A special seal and guide system seals
off the interior to atmosphere. The gas
spring is filled with compressed nitrogen.
The filling pressure acts on the
cross-sectional area of the piston rod
and produces an extension force, which
can be freely selected within physical
limits. 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 less, it contracts.
