It is composed of the following parts: the device comprises a pressure cylinder, a piston rod, a piston, a sealing guide sleeve, a filler (inert gas or oil-gas mixture), an in-cylinder control element, an out-cylinder control element (a controllable gas spring), a joint and the like. The principle is that inert gas or oil-gas mixture is filled in a closed pressure cylinder, the pressure in a cavity is several times or dozens of times higher than the atmospheric pressure, and the motion of a piston rod is realized by utilizing the pressure difference generated by the cross section area of the piston rod smaller than that of the piston.
The controllable spring component of the gas spring, which is filled with compressed air and whose end is fitted with a needle-type seal, can be reset by the action of air pressure when the other components are pressed down, is one of the important components. In the prior production process, after the needle-type sealing element is installed, a worker manually uses a tool to charge compressed air into the spring body, the time duration is controlled by the worker by the sense of the worker, and the pressure value is difficult to ensure to be consistent due to the fact that the process parameters require the air pressure to reach a certain value, so that defective products and waste products are frequently generated.
