shock absorber
A hydraulic shock absorber dampens suspension movement by forcing a piston to move through oil. Holes in the piston are covered by spring-loaded valves. These valves slow the flow of oil through the holes to control damping rate: the smaller the valve opening, the slower the oil flow and the greater the damping. Adjustable shock absorbers vary the shock’s damping rate by varying the size of the valve opening, either by adjusting the spring preload or by selecting a different size oil flow orifice. By using a small motor or a solenoid to operate the valve, damping rate can be adjusted “on-the-fly” by the driver and/or by the computer.
