Power steering was invented earlier in the century to deal with the excessive weight of
modern vehicles.

Power steering relies on a simple principle- a hydraulic pump running off a belt driven
by the engine places a small amount of fluid under pressure, which in turn assists the
steering mechanism in directing the tires as you turn the steering wheel. The system
typically includes a pump, a pressure hose assembly, a control valve, and a return line.

There are three types of power steering systems used on passenger vehicles. The first
and most popular is known as power rack-and-pinion steering. It utilizes a power unit
built directly into the rack assembly. When the wheel turns, an internal rotary valve
directs the flow of power steering fluid to the proper end of the power cylinder. The
difference in pressure on either side of this cylinder assists in moving the rack, thereby
easing steering. A control valve then returns excess fluid to the main reservoir.
