What ARE Twin-Tube Shocks?

Twin-tube design shock absorbers, sometimes referred to as hydraulic or gas-hydraulic shock absorbers, havetwo tubes one for the piston to work in and one known as a reservoir tube for the excess oil to move in and out of. As the piston rod moves in and out of the shock the oil moves through valves between the two tubes ensuring controlled damping occurs to control the suspension of the vehicle. When the piston rod is pushed in, oil flows without resistance from below the piston through the orifices and the non-return valve to the volume above the piston. Simultaneously, a quantity of oil is displaced and forced to flow through the bottom valve into the reservoir tube. The resistance, encountered by the oil on passing through the bottom valve, generates the bump damping. When the piston rod is pulled out, the oil above the piston is pressurized and forced to flow through the piston. The resistance, encountered by the oil on passing through the piston, generates the rebound damping.
