What component inside the transfer modules stops the leak if it is in the HYD pump?

• A. The Transfer Valve
• B. The Relief Valve
• C. The Check Valve
• D. The APU Accumulator

Answer: (A)

The transfer valve is the component that isolates and blocks the flow within the transfer module when theHYD pump is active. Its job is to close off the path from the HYD pump to the rest of the system, preventing fluid from leaking into other circuits. By seating into position, it effectively stops the leak path inside the transfer module.

Relief valves only vent excess pressure, not isolate leaks. Check valves prevent reverse flow but don’t isolate a leak path when the pump is in use. The APU accumulator stores hydraulic energy for the APU and isn’t involved in stopping a leak in the HYD pump.
