Gas springs are a proven and reliable method of counterbalancing covers, flaps and objects. A gas spring is an energy-storage device filled with nitrogen. A gas spring stores energy by compressing the nitrogen gas within the gas spring. While the gas spring is compressed, the gas chamber volume is reduced due to the intrusion of the shaft into the gas spring tube; thereby causing the gas pressure to rise-storing more energy.

This stored energy produces a force in the extension direction making the gas spring extend. More versatile than mechanical springs, Destek gas springs offer the advantages of speed-controlled dampening, cushioned end motion, simple mounting, compact size, flat force curve, and a wide range of available forces.
