Gas Spring
Gas spring is a part that can realize the functions of support, cushioning, braking, height and Angle adjustment, etc. In construction machinery, it is mainly used in cover, door and other parts.The gas spring is mainly composed of piston rod, piston, sealing guide sleeve, filler, pressure cylinder and joint, among which the pressure cylinder is a closed chamber, filled with inert gas or oil and gas mixture, the pressure in the chamber is several times or dozens of times of atmospheric pressure. When the hydraulic gas spring acts, the pressure difference between the two sides of the piston is used to realize the movement of the hollow piston rod. Adjustable gas struts has different structures and types to meet different use needs, construction machinery mainly uses compression gas spring, this type of gas spring mainly plays a supporting role, only the shortest and longest two working positions, can not stop itself in the stroke.
