Damped Gas Springs are compact devices integrating a gas spring and a damper in one unit, commonly used in moving masses at a specific velocity such as gates and door panels. As with dampers, the mass “M”, stroke “S” and time, ”T” are required to specify a damped gas spring. However, unlike dampers which generate a resisting force, damped gas springs output a controlled drive force capable of displacing the mass at the required velocity.

IGS damped gas springs are mainly categorized as fully damped and partially damped gas springs:

Partially damped gas springs can be described as compression gas springs filled with high volumes of oil (Figure 5). These springs create a two-stage damping effect as the piston is passing through the gas (considerably less viscous than oil) and oil regions.
