L4-8 Steering Circuit L04037
Steering Right
(Refer to Figure 4-5):
Only a few differences occur between steer left and
steer right. When the operator turns the steering
wheel right, oil is supplied out ports R and LS of the
steering control unit. The oil enters the flow amplifier
assembly at port R and shifts the directional valve
the opposite direction. The oils flow through the
amplifier valve exactly the same.
The combined oil from the amplifier valve passes
through the center area Q of the directional valve to
port CR where it goes to the opposite ends of the
steering cylinders to turn the wheels right. The
returning oil comes back through port CL to go to the
tank. The LS oil operates exactly the same as steer
left.
