🔍 Key Concepts

• Hydraulic replenishing circuit in an anchor windlass system and what it normally supplies besides makeup oil • The function of the components labeled J, K, L, C, D, E, M in the diagram and which of them must have continuous pressurized oil available • Difference between oil used for control/actuation (valve shifting, brakes, limiters) vs. oil used for filtration/conditioning only

💭 Think About

• Trace the pressurized fluid line used for automatic replenishment and see what other component that same line feeds in the diagram • Ask yourself which option would logically require a steady, reliable source of pressure any time the system is pressurized • Consider which listed functions (horsepower limiter, brake, shifting valve L, oil conditioning) are usually controlled by small pilot lines versus large flow working lines

✅ Before You Answer

• Verify which symbol in the diagram represents the replenishing pump / source of pressurized fluid and follow its discharge line • Confirm what component the replenishing line feeds after passing the point marked for automatic replenishment • Check whether the function described in your chosen option would realistically be powered by the same low‑volume, continuous-pressure line that handles makeup oil, instead of by the main high‑flow circuit
