System Description
Fluid Flow Diagram
The system is a compact rotary-valve,type power steering, connected to the steering gearbox. The fluid pressure is pro-
vided by a vane-type pump which is driven by the engine crank pulley. The amount of fluid and pressure is regulated by
the flow control valve built into the pump. The fluid pressure from the pump is delivered to the valve body unit around the
pinjon of the steering gearbox. The valve inside the valve body unit controls the hydraulic pressure and changes the direc-
tion of the flow. The fluid then flows to the power cylinder, where rack thrust is generated. Fluid returning from the power
cylinder flows back to the reservoir, where the fluid is
"filtered" and supplied to the pump again'
