What is the Principle of Gas Springs?

Gas spring is a kind of can realize the support, cushioning, braking, height and angle adjustment functions of the part, in the construction machinery, mainly used in the cover, door and other parts. The gas spring is mainly composed of piston rod, piston, seal guide sleeve, filler, pressure cylinder and joint, in which the pressure cylinder is a closed cavity, the internal filled with inert gas or oil and gas mixture, the pressure in the cavity body is several times or dozens of times the atmospheric pressure. When the gas spring is in effect, the pressure difference on both sides of the piston is used to realize the movement of the piston rod. Gas springs have different structures and types, to meet different use needs, the main use of compressed gas springs on construction machinery, the main gas spring plays a supporting role, only the shortest, longest two working positions, in the trip can not stop on their own.

Performance of gas springs:

Air spring is a can be a force-saving lift spring, can be divided into self-locking gas spring (e.g. seat bottom lift, boss chair backrest, etc.), can not self-lock air spring (e.g. car tailbox, closet door lift support), gas spring structure is mainly composed of sleeve, piston and piston rod, etc., in the sleeve to add high-pressure air or high-pressure nitrogen, due to the piston end area of different pressure difference, push and move the rod and support.
