Steering
9803/7130 Issue 1
Steer Unit Operation 4
- Right Turn, Unassisted
The illustration shows the circuit operation with the
engine stopped. Turning the steering wheel rotates
the inner spool A until the cross pin engages with
and rotates outer sleeve B, metering oil to the
stator D, and pumping it out to rams 40 and 41
under manual pressure only.
As there is no supply from the pump, oil from one
side of the rams, supplemented by exhaust oil if
necessary, is used to feed the other side via non-
return valve F.
