HELI CPC 25 User Manual

Fig.4-4 Control valve
4.4.2 Pressure valve
It is used to keep the oil pressure within 1.1-1.4MPa. Through the valve and the
relief valve, the pressure oil is sent to the torque converter.
4.4.3 Adjusting valve
It is positioned between the inching valve and the operation slide valve. The
adjusting valve comes to work as soon as the operation slide valve is opened, so as to
reduce the shock from the engagement of either clutch.
4.4.4 Relief valve
The relief valve connected with the transmission case keeps the oil pressure in
the torque converter within 0.5-0.7MPa to prevent air corrosion.
4.4.5 Inching valve
It is fixed in the outside of the transmission. Its spool is connected with a
connection rod of the inching pedal. When the pedal is stressed, the spool moves to
right, and the oil pressure in the clutches is lowered temporarily to get the inching of
the truck (See Fig.4-5).
