The steering gear power steering function is schematically displayed in Fig 1 and Figure.
The force of oil pressure built up in the power steering pump affects the piston on the steering rack. The oil flow to the right or left-hand side of the piston is regulated in the valve housing. External pipes lead to both sides from the valve housing.
The rotary valve has three radial grooves, a small one that is fed by servo pump and an upper and a lower groove that are connected with the working cylinders via the outer pipes.
