How is the lube oil supplied to each bearing in a gas turbine engine controlled?

🔍 Key Concepts

• How lube oil flow is DISTRIBUTED to multiple bearings in a gas turbine • The difference between a device that MOVES oil (creates pressure/flow) and a device that METERS or SPLITS oil flow • How small fixed restrictions are used to CONTROL flow rate to individual components

💭 Think About

• Which choice specifically controls the AMOUNT of oil going to each individual bearing rather than just supplying pressure to the whole system? • In a multi‑bearing gas turbine, would you more likely use one common control element for all bearings or a separate, fixed metering element at each bearing? • Which option is commonly used as a simple, reliable flow‑metering device with no moving parts in high‑speed engines?

✅ Before You Answer

• Identify which components are pumps or general system regulators versus individual flow‑metering devices • Ask yourself which option would be placed right at or near each bearing to set its specific flow rate • Eliminate any option whose main job is to pressurize or regulate system pressure, not to meter flow to each bearing
