6.1 IN NEUTRAL
If the steering wheel is not rotated, valve plate (3) keeps
in neutral by using a 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 the gear pump will be drained
to the port.
Besides, flow from cylinder port R and L will be shut off
at control valve.
The steering cylinder will not move and it keeps the
front wheels straight or at given angle without motion.

6.2 TURNING TO THE RIGHT
If the steering wheel is rotated to the right, the move-
ment will be passed to control valve through the drive
plate, GEROTOR and drive link.
Valve plate (3) rotates to the right on the manifold and
is located in the opposite direction of the valve plate
(3). Port P flow of control valve is connected to
GEROTOR (5).
STATOR of GEROTOR (5) rotates as the steering wheel
(2) is rotated, and performs metering function and
passes oil as steering wheel (2) is rotated.
Oil that passed through GEROTOR (5) will flow to the
rear of control valve, connected to cylinder port R and
moves the steering cylinder (6).
Front wheel moves as corresponding angle as oil
passed. If steering cylinder (6) operated, returned oil
will be flown to cylinder port L, connected to port T from
control valve and returned to transmission case.
