🔍 Key Concepts

• Trace the oil flow path on the diagram from oil inlet, through the heater, separator, and to the oil outlet line and pressure sensor/indicator. • Look at the function of the three-way valve (V1) and how it diverts oil between recirculation and outlet. • Consider what system conditions would actually reduce pressure at the outlet line versus just affecting separation quality or sludge build‑up.

💭 Think About

• If the outlet pressure is low, is that more likely caused by a restriction/blockage, or by a valve position that prevents flow from reaching the outlet line? • How would insufficient heating of the oil change viscosity and separation, and would that mainly affect quality of separation or pressure in the outlet line? • Compare what would happen to outlet pressure if sludge accumulates in the bowl versus if the three‑way valve stays closed to the outlet side.

✅ Before You Answer

• Identify exactly where the pressure is being sensed in relation to V1, the heater, and the separator on MO-0127. • Verify which choice(s) would directly affect flow to the outlet line, rather than just separation efficiency or bowl condition. • Check how the normal (proper) setting of any valve in the outlet line would influence pressure: would it tend to maintain, raise, or lower outlet pressure?
