Proportional Reducing Valve
After the gear shifting is completed, this valve has
function which gradually rises the pressure in the clutch
(4) in order to make a clutch engaging for without shock
and smoothly.
When the gear shifting is completed, the pressure
switch is turned ON.
pressure switch, the microcomputer of ECU calculates
and judges the charging of pressure and its time
according to the oil temperature sensor and gear shifting
period, and the traveling speed and speed acceleration
according to the traveling speed sensor.
instructions from
proportional reducing valve adjusts pressure in the clutch
to become a appropriate acceleration.
