The type gas spring has a longer length in the free state (small stroke), and can be compressed to a small length (large stroke) after being subjected to external pressure greater than its own thrust. The free-type gas spring has only a compressed state (two kinds of external pressure and free state), and it cannot lock itself during its stroke. The free-type gas spring mainly plays a supporting role. The principle of the free-type gas spring is that the pressure tube is filled with high-pressure gas, and the moving piston has a through hole to ensure that the pressure in the entire pressure tube […]
