Question: A new hydraulic reservoir is being fabricated. To facilitate proper de-aeration of the hydraulic fluid, what internal feature is essential?
Answer options: ✅ A baffle plate separating the pump suction line from the return line.
- A highly polished internal surface to reduce fluid friction.
- An internally mounted heat exchanger for cooling.
- A submerged, unrestricted filler neck.
Correct answer: A baffle plate separating the pump suction line from the return line.
Explanation: A baffle plate strategically placed within the reservoir is crucial. It directs the returning fluid along a longer path, allowing more time for air bubbles to escape to the surface and for contaminants to settle, preventing them from being immediately drawn back into the pump.
