Operating Pressure (P-A)
The inscribed gear type oil pump is installed into the torque converter housing and is driven via the drive flange of the
torque converter.
The operating pressure produced from oil pump supplies oil pressure to main line in hydraulic system to operate the
actuator. The operating pressure is the highest pressure in the hydraulic system. All other pressures are derived
from it.
The operating pressure is regulated at the operating pressure control valve depending on load (modulating pressure)
and driving range (C1, C2 pressure). The spring in the operating pressure control valve adjusts a minimum pressure
level (base pressure).
Lubricating Pressure (P-sm)
This pressure limits the pressure in torque converter and lubricates and cools down the mechanical transmission
parts. At the operating pressure control valve, excess fluid is diverted to the lubricating pressure control valve (1) and,
from there, regulated for transmission lubrication use (including torque converter).
