Lift Arm Lower
Fig 20.
Fig 20. (
X E-24) shows lift arm lower selected. On servo
machines, when the joystick is moved servo oil is supplied
to the appropriate end of the tilt spool 8b which moves to
select the lower service. On manual valves the spool is
operated mechanically by movement of the control lever.
The oil entering the valve block is diverted by the lift spool
8b to load hold check valve 8g which opens to allow
pressurised oil to flow out of the valve block to operate the
lift ram.
Oil returning from the opposite end of the lift ram enters the
valve block and lifts check spool 8j which allows the oil
restricted flow though the centre of spool 8b before it
enters the neutral circuit gallery and returns to tank.
