Clutch Valve
The clutch valve (5) changes the flow of the oil
flowing to the GST clutch to do
"ENGAGE"
/
"DISENGAGED"
of the clutch.
Except for during gear shifting, the oil of the pilot
circuit flows in from the
A
-port to push the spool to the
right when the pilot circuit is pressurized. Therefore, the
oil from the low-pass valve (7) and proportional reducing
valve (8) flows in from
B
and
C
-port, flows out from the
D
-port, and flows to the GST clutch (6).
When the pilot circuit pressure is zero, that is, from
the start to the left with the spring (3) to cut the oil flow of
B
and
C
-port, and stopping the oil flow to the GST clutch
(6). Furthermore, the oil of the GST clutch flows in from
D
-port, and is drained from
E
-port, and then the GST
clutch is disengaged.
