Which component is primarily responsible for handling pressure surges in the hydraulic system?

• A. Hydraulic accumulator
• B. HYD SOV
• C. Anti-skid controller
• D. ADG

Answer: (A)

Pressure transients in a hydraulic system are smoothed by the hydraulic accumulator. An accumulator acts as a buffer by storing hydraulic energy as a precharged gas (or spring) behind a piston or bladder. When a surge occurs—such as a sudden valve closure or a rapid change in pump flow—the fluid compresses the gas, absorbing the energy and keeping the pressure from spiking. Later, as demand drops or the pump lag catches up, the accumulator releases fluid back into the line to maintain steadier pressure. This damping effect helps protect components and keeps actuators operating smoothly. The hydraulic SOV is mainly a flow-control valve that directs where fluid goes; it doesn’t inherently damp pressure surges. The anti-skid controller governs braking-related hydraulics, not surge management. The ADG provides electrical power in emergencies, not hydraulic pressure stabilization.
