Line-Pressure Control
- The oil pump delivery pressure (line pressure) is regulated to the constant pilot pressure by the pilot valve.
- The pilot pressure applied to the pressure modifier valve is regulated by the line pressure controlling line pressure duty solenoid and changed into the pressure modifier pressure.
- The pressure modifier valve is an auxiliary valve for the pressure regulator valve, and it creates a signal pressure (pressure modifier pressure) for regulating the line pressure to an optimum pressure corresponding to the driving conditions.
- This pressure modifier pressure is applied to the pressure regulator valve to control the oil pump delivery pressure.
- The pressure modifier pressure regulated by the pressure modifier valve is smoothed by the pressure modifier accumulator and pulsation in the line pressure is eliminated.
