Power steering system.

When the driver is not exerting force such as when driving in a straight line the system shouldn t provide any assist. Power assisted steering overcomes the problem. Valves in the steering rack or box open whenever the driver turns the wheel allowing oil into the cylinder. The electric power steering system is typically part of the hi speed can bus on the vehicle.

A power steering system should assist the driver only when he is exerting force on the steering wheel such as when starting a turn. The oil works a piston that helps to push the steering in the appropriate direction. In motor vehicles a power steering system helps drivers steer the vehicle by augmenting steering effort needed to turn the steering wheel making it easier for the vehicle to turn or maneuver. The engine drives a pump that supplies oil under high pressure to the rack or the steering box.

The device that senses the force on the steering wheel is called the rotary valve.
