Multiple Choice

The basic working principle of a hydraulic shock absorber is based on which mechanism?

The damping action comes from hydraulic fluid being forced through a restricted path as the piston moves. When the suspension compresses or rebounds, fluid must flow through small orifices or valves, creating resistance that converts kinetic energy into heat. The size and design of these orifices control how much damping occurs. Gas pressure can help with ride quality and prevent cavitation, but the basic mechanism that provides damping is the controlled flow of hydraulic fluid through an orifice.
