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"

.  By  means  of  turning  on  the

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.  By  these

instructions  from  microcomputer  of  ECU,  the

proportional  reducing  valve  adjusts  pressure  in  the

clutch to become a appropriate acceleration.
