Integral Gear Power Steering Fluid Flow Diagram - Ford Bronco Gear Box Schematic

This schematic, titled "Integral Gear Power Steering Function," illustrates the hydraulic fluid flow inside an integral power steering gear box under three operating conditions: Straight, Right Turn, and Left Turn. Each of the three cutaway drawings shows the steering gear assembly with two labeled hydraulic connections, the Pressure Port and the Return Port, indicated by arrows. A legend at the lower right distinguishes Low Pressure Oil (shown as white/unshaded areas) from High Pressure Oil (shown as black/shaded areas). In the Straight-ahead view, no areas are shaded high pressure, indicating balanced pressure. In the Right Turn view, high-pressure oil fills one side of the gear housing, and in the Left Turn view, high-pressure oil fills the opposite side and areas around the valve body, demonstrating how the rotary valve directs pressurized fluid to opposite sides of the power piston depending on steering direction. The document contains no year, make, model, part numbers, torque specifications, or fluid capacities, it is purely a functional/hydraulic flow illustration. It was uploaded as reference for a 1990 Ford Bronco, and nothing in the diagram contradicts that application, though the diagram itself is generic and unbranded.
