Rcgulator Valve
The r€gulator valve maintains a constant hydraulic pressure from the oil pump to the hydraulic control system, whil€
alEo furnishing oil to the lubricating system and torque convener.
Oil flows through B and B'. The oil which enters through B flows thfough the valve orifice to A, pushing the regulator
valve to the right. Acco.ding to the level of hydraulic pressure through B, the position of the valve changes, and the
amount of the oil thlough D from B'thus changes. This operation is continued. thus maintaining the line pressure.

Siator Reaction Hydtaulic Pressure Control
Hydraulic pressure increase, according to torque, is performed by the regulator vslve using stator torque reaction. The
stator shaft is splined to the stator and its a.m end contacts the fegulator spring cap. When the car is accelerating or
climbing (Torque Convener Range). stator torque reaction acts on the stator shalt and the stator shaft arm pushes the
rsgulator spring cap in this - direction in proportion to the reaction. The spring compresses and the regulator valve moves
to increase the regulated control pressure or line pressure. Line pressure is maximum when the stator reaction is maximum.
