Gas spring performance

It is a stand-alone device capable of supporting very heavy forces. Gas springs are used to safely and easily raise or lower an object, such as lids, bonnets, gates, etc., without the use of external energy.

A piston and a rod move within a cylinder containing pressurised nitrogen gas, which depends on the force to be moved. The amount of pressure depends on how much force in the spring you need to do a particular job.

Gas springs offer a wide selection of sizes, force variants, retention and fixings. They have a compact design, do not require much space, providing a quick and easy assemble.

ALONTEC springs have much more innovative, comfortable and ergonomic mechanisms, as well as a long maintenance free life, increasing its added value.



The movement cycle of a gas spring is the trajectory of its strength along its route, from the state of extension to compression and vice versa.

Movement depends on the relation between the volume of the rod and the volume inside the cylinder. Different combinations of the trajectory, the diameter of the rod and the cylinder allow for infinite variations of movement.

The movement represents the behaviour of the forces in the direction of the extension (Movement = F2 / F1). Force F1 is measured 2mm before the end of the extension movement and determines the value of the spring force.



Diagram of your Gas Spring Route versus Time

Here we show the path our spring makes in millimetres from position A, in which the rod is contracted, to position B, in which the rod is extended, or conversely, when the process would be compressed.

Two types of damping can be distinguished; a pneumatic cushioned zone, containing gas in the spring and a hydraulic cushioned zone, exerted by oil.



The Influence of Temperature on Force

In the following diagram we can see the increase and decrease percentage applicable to the force of the spring depending on the temperature.
