How does a power assisted steering system work?

Heavy gearing can be troublesome when parking in confined spaces. Power-assisted steering overcomes the problem. The engine drives a pump that supplies oil under high pressure to the rack or the steering box. Valves in the steering rack or box open whenever the driver turns the wheel, allowing oil into the cylinder.
