WHAT IS GAS SPRING
A gas spring (also called a gas strut, gas lift, or gas shock) is a type of mechanical device that uses compressed gas—usually nitrogen—sealed inside a cylinder to exert force and provide controlled motion. It works like a spring, but instead of using coiled metal, it relies on gas pressure and hydraulic oil for smooth operation.
Key Components:
Cylinder: The outer tube that holds the gas and oil.
Piston rod: Moves in and out of the cylinder.
Piston: Inside the cylinder, helps regulate the movement of gas.
Seals and guides: Prevent leaks and guide the piston rod.
What are the types of gas springs?
Gas Springs can be divided into several types according to their function and structure:
Standard Gas Springs:
In its most basic form, an air spring can only provide one-way support (e. g. , when a chair is falling, it provides resistance, but can not actively rise) .
On the basis of the standard gas spring, the"Lockable gas spring function" is added, which can be fixed in any position like the brake, and is suitable for hovering scenes (such as car trunks, surgical beds) .
By adjusting the internal air pressure, the support force can be varied to suit scenarios requiring flexible adjustments (such as heavy machinery support) .
Hydraulic damping is added to the air spring to make the movement slower and smoother, which is suitable for cushioning scenarios (e. g. Furniture Lowering, car seat adjustment) .
