When Pressure Compensation Mechanism Off; When The Pressure Compensating Mechanism Is Inactive - Toyota 7FBEF 15 Service Manual

When pressure compensation mechanism OFF

When solenoid C1 is not energized and the non-leak valve is open, the pressure oil from chamber (c)
flows through orifice Q, then returns to the tank via chamber (g). Now chamber (c) has the same
pressure as the tank, so all the pressure oil from port P returns to the tank via part E.
