Shock absorber

The structure of the Shock Absorber is that a Piston rod with a piston is inserted into the barrel, and the barrel is filled with oil.   The piston has an orifice so that the oil in the two parts separated by the piston can complement each other.   Damping is generated when viscous oil passes through the orifice.   The smaller the orifice, the greater the damping force.   The greater the viscosity of the oil, the greater the damping force.   If the size of the orifice is constant, when the damper operates at a high speed, the damping will influence the absorption of the shock.   Therefore, a disk-shaped leaf spring valve is provided at the outlet of the orifice.   When the pressure becomes large, the valve is opened, and the opening of the orifice is increased, and the damping becomes smaller.   As the piston moves in both directions, leaf spring valves are mounted on both sides of the piston, called the compression valve and the extension valve.
