In this case, additional force is provided by high-pressure hydraulic fluid, which presses on a piston connected to a toothed rack
By rotating the steering wheel, the driver determines which cavity the fluid will flow into. This rotation is transmitted to a system of valves that regulates the direction and volume of the fluid flow. The pressure in the hydraulic system is created by a vane pump, driven by the engine via a V-belt or poly-V-belt.
