The spool in valve (3) was last moved by solenoid
(3b): oil flowing in from P3 flows through the internal
galleries of the spool and exits at port A3. From
here, oil enters valve (2), whose spool was last
moved by solenoid (2b). Oil flows through port P2
and exits through port T2, cutting off flow to the rear
steering cylinder. Now the oil returns in valve (3),
entering through port B3 and flowing out through
port T3. From here, oil enters the front steering cyl-
inder.
