What is an integral power-steering system?

An integral power-steering system is a type of power steering system in which the power steering pump, control valve, and steering rack are all integrated into a single unit. This design simplifies the power steering system and reduces the number of components that can fail.

Integral power-steering systems are typically used in smaller vehicles, such as passenger cars and light trucks. They are also used in some larger vehicles, such as SUVs and vans.

Here is a more detailed explanation of how an integral power-steering system works:

1. The power steering pump draws fluid from the power steering reservoir and pumps it through a high-pressure hose to the control valve.

2. The control valve directs the high-pressure fluid to the steering rack.

3. The high-pressure fluid acts on the steering rack to assist the driver in turning the wheels.

4. When the driver turns the steering wheel, the control valve also opens a return line, which allows the high-pressure fluid to return to the power steering reservoir.

Integral power-steering systems are a reliable and efficient way to provide power steering to vehicles. They are also relatively easy to maintain, as there are fewer components that can fail.
