FLUSHING RELIEF VALVE
When the oil is sent under pressure to the A port, the oil that activated the motor returns to the pump through the B port.

The pressurised oil sent to the A port is also introduced into the chamber C. It now pushes the selector valve (1) to the right ( ). This opens communication between the B port and the oil gallery D, which is connected to the overpressure limitation valve (2).

If the pressure present at port B exceeds the calibration value of the overpressure limitation valve (2), this valve will open and discharge the excess oil into the reduction gears.
