The Structure Of The Shock Absorber

The piston rod with the piston is inserted into the cylinder, and the cylinder is filled with oil. The piston has an orifice, so that the oil in the two spaces separated by the piston can supplement each other. Damping is produced when viscous oil passes through the orifice. The smaller the orifice, the greater the damping force, and the greater the viscosity of the oil, the greater the damping force. If the size of the orifice remains the same, when the shock absorber works fast, the damping will affect the shock absorption. Therefore, a disc-shaped leaf spring valve is installed at the outlet of the orifice. When the pressure increases, the valve is pushed open, the opening of the orifice becomes larger, and the damping becomes smaller. Since the piston moves in both directions, leaf spring valves are installed on both sides of the piston, which are called compression valves and expansion valves.
