There is an orifice on the piston, so that the oil in the two spaces separated by the piston can supplement each other
Damping is generated when viscous oil passes through the throttle hole. The smaller the throttle hole, the greater the damping force. The greater the oil viscosity, the greater the damping force
If the size of the orifice remains the same, when the pneumatic ball valve operates at a high speed, excessive damping will affect impact absorption
Matching skill 1) Check whether the product provides 2-3 inch lifting requirements, some products only provide 2 inch lifting, and it is easy to pull to a greater extent in off-road after barely using the 3 inch lifting
2） Whether the diameter of the central telescopic rod of the shock absorber can reach more than 16 mm is a basic indicator of strength
3） Whether the upper and lower connecting sleeves of the shock absorber are high-strength polyurethane sleeves is also an important basis for ensuring long-term high-strength use, because it is difficult for ordinary people to use them for a long time under high strength
