The function of each major component is described below:

Power Steering Unit
Refer to the previous page.

Oil Pump

The oil pump uses the power of the engine to send hydraulic fluid to the power steering unit.
An oil pressure relief valve and an oil flow relief valve are installed to the oil pump.
The oil pressure relief valve prevents any excessive oil pressure from reaching the hydraulic circuit.
The oil flow control valve controls the hydraulic fluid volume within the hydraulic system.  It prevents too much fluid
from entering the system.  This, in turn, prevents harmful heat build-up.

Oil Reservoir and Piping

The oil reservoir stores and filters the hydraulic fluid.
