Additional Technical Detail: Flushing Relief Valve

When oil is pressurized to the A port, it returns the activated motor oil to the pump through the B port. The pressurized oil in the A port is directed into chamber C, moving the selector valve to the right, establishing a connection between the B port and oil gallery D, linked to the overpressure limitation valve. If the pressure at port B surpasses the valveu2019s calibration, the valve activates, channeling excess oil into the reduction gears.
