Solenoid Modulator Valve

This valve Repressurizes the hydraulic pressure (line pressure) generated by the oil pump and sends the fluid to the throttle pressure control solenoid. The hydraulic pressure (line pressure) applied to (2) passes the fluid passage in the valve into the chamber (A), trying to move the valve to the left. On the other hand, as a spring force to push the valve to the right is also applied to adjust the valve opening between (1) and (2), the Repressurized hydraulic pressure acts on the throttle pressure control solenoid through (1).
