Welcome to shuangyuan,manufacturer of gas spring, disc spring, die spring etc.

Prev: A simple classification of gas springs Next:About compression spring

Gas spring is the principle gas pressure in the sealed cylinder filled inert gas or gas mixture, so that the pressure chamber is several times higher than the atmospheric pressure, or a few times, using cross-sectional area smaller than the piston rod cross-sectional area to the pressure difference to achieve the movement of the piston rod.

As a fundamental principle of the different gas spring than normal spring has very significant advantages: a relatively slow pace, little change in the dynamic force (generally less than 1:1.2), easy to control;

Drawback is that relatively small volume without coil spring, high cost, relatively short life.

The difference is that with mechanical springs, gas springs with near-linear elastic curve. Standard gas springs between the elastic coefficient of X between 1.2 and 1.4, other parameters can be flexible according to the definition of requirements and conditions.
