A gas spring is a highly versatile device that finds its application as a support, buffer, brake, height adjuster and angle adjuster in various industrial settings. It comprises several components such as a pressure cylinder, piston rod, sealing guide sleeve, piston, filler (oil-air mixture or inert gas), in-cylinder control elements, out-of-cylinder control elements (in the case of controllable gas springs), and joints.
Gas springs operate by filling a sealed cylinder with an inert gas or an oil and gas mixture, creating pressure several times higher than atmospheric pressure within the cavity. The piston rod moves as the pressure differential between the piston and the rod is utilized. This approach offers numerous advantages over conventional springs, such as slow speed, stable dynamic force (generally within a ratio of 1:1.2), and ease of control. However, compared to coil springs, gas springs have a larger relative volume, higher cost, and a shorter lifespan.
Gas springs, also known as support rods, angle adjusters, gas pressure rods, or dampers, are versatile components that find applications across several fields. They come in several types, depending on their structure and function. These include self-locking gas springs, free-type gas springs, traction gas springs, swivel chair gas springs, random stop gas springs, gas pressure rods, and dampers. Gas springs find extensive use in diverse fields such as aviation, machinery manufacturing, furniture, medical equipment, and automobiles, among others.
