Design and Function
ECKOLD Gas Springs are hydropneumatic, closed and maintenance-free adjustable elements.
The spring force F1 results from the internal pressure (160 bars without load) which is generated by the filling gas, nitrogen.
The piston rod is extended when no load is applied, once a load is applied to the piston rod pushing it inwards, the volume in the cylinder is reduced, and the gas is compressed. The gas spring force increases (progression) depending on the diameter of the piston rod and the volume of the cylinder.
Eckold gas springs contain an oil filling for lubrication and end damping.
Eckold gas springs are available in steel, in AISI 303/304 and AISI 316L/316Ti.
