It is light, and small in size, and can have a
Characteristics of the spring can be set freely.
Operation is smooth. (No mechanical friction is
made, and noise and shock during compression and tension can be
Operation is easy.
Installation is easy.
Principle of Operation:
As shown below, high-pressure gas is sealed in the
cylinder gas chamber of the free type gas spring, while the Piston Rod is
compressed. For this reason, the Piston Rod always carries repulsive power
in the direction of expansion. Hence, the degree of repulsive power is
dependent upon the pressure inside the gas chamber and the outer diameter
of the Piston Rod.
Pressure(P) applied to surface A creates Force
As Piston Rod is pressed, Gas Chamber of Cylinder
is reduced as much as volume of Piston Rod and Gas is expanded,
therefore pressure increases.
