Gas Springs, also known as Gas Struts are versatile and essential components used across various industries due to their functionality and efficiency.
Here you can explore the various types and how they work.
Back to Gas Strut and Cam-Stays
Gas springs, also known as gas struts, are versatile devices that provide support and motion control in various applications, from automotive to furniture. These components function by utilising compressed gas, contained within a cylinder and compressed by a piston, to exert a force. This force is typically used to support the weight of an object, making it easier to lift or sustain in an open position. The key to their operation lies in the balance between the gas pressure and the mechanical parts of the strut, allowing for smooth and controlled movement. Gas springs can be designed to provide different levels of resistance, making them suitable for a wide range of uses.
At JET PRESS we stock a wide range of Gas Struts, if you are looking to replace an existing Gas Strut, use our configurator tool to find your exact match.
A gas strut or gas spring is a sealed energy source containing an inert gas (nitrogen) and oil. Being self-contained units, these useful devices require no power source or maintenance.
Nitrogen is forced under pressure into the cylinder of the unit. The internal pressure exceeds atmospheric pressure and generates an outward force on the rod, making the rod of the unit extend.
With the pressure being equal on both sides of the piston, there is more force acting in direction ‘B’ than in direction ‘A’. This forces the rod of the gas spring out.
When the rod is compressed into the cylinder, the internal pressure and the output force increase according to the volume displaced by the rod. On extension or compression, gas is metered from one side of the piston to the other via a small orifice.
