What is gas spring?
Gas springs, also known as gas struts or gas lift supports, are devices used to support and control the movement of various objects, such as automobile tailgates, office chair seats, hoods of vehicles, and more. They work based on the principles of pneumatics and use compressed gas, typically nitrogen, to provide a controlled force to assist in lifting or lowering an object.
How does gas spring work?
Gas springs consist of a cylinder filled with high-pressure nitrogen gas and a piston rod. The piston rod is connected to the object that needs to be lifted or supported. When the gas spring is in its resting state, the gas is compressed on one side of the piston, and the rod is extended.When you apply force to the object connected to the gas spring, such as when you press down on an office chair seat or lower the tailgate of a car, the gas spring supports the weight of the object. It counteracts the force you apply, making it easier to lift or lower the object.Some gas springs have a locking feature that allows them to hold an object in a specific position until you release the lock. This is often seen in chairs or car hoods. By releasing the lock or applying force in the opposite direction, the gas spring allows the object to move again.
How Gas Springs Differ From Mechanical Springs?
Gas Springs: Gas springs use compressed gas (typically nitrogen) to store and release energy. They rely on the pressure of the gas within a sealed cylinder to exert a force. The gas spring extends when force is applied and compresses when force is released.
Mechanical Springs: Mechanical springs, also known as coil springs or leaf springs, store and release energy through the deformation of a solid material, such as metal or plastic. When a mechanical spring is compressed or stretched, it stores potential energy, which is released when the spring returns to its original shape.
