Compression gas springs are a multipurpose product of a simple cylindrical shape with di erent mounting variants producing an extending power under pressurized nitrogen. The compression of the piston rod into the cylinder compresses nitrogen, resulting in the formation of force, which extends the piston from the cylinder. The amount of force depends on the cross section of the piston rod, the cylinder volume and the amount of nitrogen therein. Gas springs are nished with a welded mesh with a diameter of 8.1 mm and a mesh thickness of 5 mm.
