How do holid oil shock absorbers work?

If you have ever waved your hand back and forth through water, then, in principle, you know how a shock absorber works. The resistance to motion you feel with your hand changes with speed – the faster you move your hand, the more energy it takes to push against the resistance of the water.A pneumatic shock absorber works much the same way. Inside the shock absorber there’s a piston that moves inside a tube that is filled with oil. As the piston moves, the oil is forced through tiny holes and valves within the piston, precisely controlling the amount of resistance to movement. This resistance to the motion converts the energy into heat. (Yes, a shock absorber that has been doing its job over a rough road does get warm!)

Although shock absorber supply have been many different designs for shock absorbers over the course of automotive history, today there are four basic types available:Twin-tube、Mono-tube、Gas-filled mono-tube、External reservoir.Sometimes these types of shock absorbers are incorporated into a strut-type suspension that uses the shock absorber as part of the spring support, but the basic principles still apply.
