ライン圧制御装置。 A regulator valve adjusts the oil discharged from the oil pump to line pressure, and the regulator valve is equipped with a signal pressure proportional to the throttle opening to control the line pressure by applying a signal pressure to the valve spool in the pressure increasing direction. In the line pressure control device for an automatic transmission, the line pressure control means is provided with line pressure drop delay means for delaying a sudden drop in line pressure when the accelerator pedal is suddenly returned. An automatic transmission line pressure control device featuring:
