🔍 Key Concepts

• Identify the illustrated component (note the spring-loaded spindle and nozzle at the bottom) and what system it most likely belongs to on a Sulzer diesel engine. • Consider whether the arrows show inlet flow into the cylinder or leak‑off/return flow away from the working space. • Think about what normally must be safely returned from this type of valve to a tank or drain line during normal operation.

💭 Think About

• Look at where the arrows start and end: is the flow moving toward the combustion chamber or away from it? • Does the path of flow go through a cooling jacket, a gas passage, or around a valve/spindle where small leakage would be expected? • On a fuel or air starting valve, what happens to fluid that is not used for actual injection/start—does it get vented, cooled, or returned?

✅ Before You Answer

• Verify whether the lower tip (label 1) is a nozzle into the cylinder or a water/air connection external to the cylinder. • Check if the flow path passes through areas that are clearly liquid-tight clearances around a valve spindle, which would suggest fuel rather than air or cooling water. • Confirm that the outlet at the top (label 7) appears to go to a return line fitting, not to a safety relief discharge or cooling water header.
