2.3 OPERATION
2.3.1 IN NEUTRAL
If the steering wheel is not rotated, control valve (3)
keeps in neutral by centering spring (4).
This time oil flow will be formed between port p (from
pump) of control valve and port T of transmission case
and all oil supplied from gear pump will be drained to
port.
Besides, flow from cylinder port R and L will be shut off
at control valve.
Steering cylinder will not move and keeps front wheel
straight or at given angle without motion.

(3) Control valve (6) Steering cylinder
2.3.2 TURNING TO THE RIGHT
When the steering wheel is rotated to the right, the
movement will be passed to control valve through drive
plate, Gerotor and drive link.
Control valve (3) rotates to the right on the manifold and
located on the opposite direction of control valve (3). Port
P flow of control valve is connected to Gerotor (5).
STATOR of Gerotor (5) rotates passing oil as steering
wheel moves.
Oil passed through Gerotor (5) will flow to the front of
control valve, connected to cylinder port R and moves
steering cylinder (6).
Front wheel moves as the oil passes through the steer-
ing cylinder (6) as it goes on to the control valve and
returned to transmission case.
