Regulator Valve
The regulator valve maintains a constant hydraulic pressure sent from the oil pump to the hydraulic control system, while
also furnishing oil to the lubricating system and torque converter.
Oil flows through B and B’. The oil which enters through B flows through the valve orifice to A pushing the regulator
valve to the right. According to the level of hydraulic pressure through B, the position of the valve changes, and the
amount of the oil through B’ from D thus changes. This operation is continued, thus maintaining the line pressure.

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