    Working Principle

    The gas spring is a hydropneumatic adjusting element, It is filled with compressed nitrogen, which acts with equal pressure on differently dimensioned cross-sectional areas of the piston.This produces a force in the extension direction.This extension force can be exactly defined within physical limits through the appropriate selection of the filling pressure.
