3. 4WD / BI-SPEED VALVE
This solenoid valve is a double acting solenoid type of
4-ports and 3-positions one. Being not electrified, it is
kept in neutral position. Therefore, oil is flowed to
neither Bi-speed clutch nor 4WD clutch when the 4WD
/ Bi-speed turn switch is switched to OFF position.
When the solenoid A (4) or solenoid B (3) is
electrified, the plunger (5) is pulled by its
electromagnetic force and its position is switched.
Then, oil pressure-fed from the hydraulic pump to P port
is flowed from A or B port to 4WD side (8) or Bi-speed
turn side (9) of the clutch (6). The return oil from the
other side is flowed to the transmission case through T
port.
