General Description of Power Steering

The power steering system consists of three parts: the power steering pump, the fluid reservoir and the power steering rack and pinion. The steering pump is a vane pump that provides hydraulic pressure to the system and is driven by the engine. It pumps from the steering fluid reservoir, which is in turn connected to the steering gear. A relief valve inside the flow control valve limits the pump pressure. Power steering rack and pinion has a rotary control valve that directs hydraulic fluid from the power steering pump to one side or the other of the rack plunger. One-piece rail plunger is connected to the rail. The rack plunger converts hydraulic pressure into a linear force that moves the rack left or right. This force is then transmitted through the inner and outer tie rods to the steering knuckles, which turn the wheels.
