🔍 Key Concepts

• Pressure control vs. flow control in lubrication systems • How positive displacement pumps behave when discharge is restricted • Common method used on engines to protect piping and maintain set pressure

💭 Think About

• Which device will automatically open and recirculate oil if discharge pressure gets too high? • Which option actually controls pressure, not just flow rate or pump speed? • If a downstream line suddenly plugs, which component prevents damage to the pump and system?

✅ Before You Answer

• Identify which choice is specifically designed as a pressure limiting device. • Eliminate any option that mainly controls flow quantity instead of system pressure. • Consider which component is normally mounted right at or near the pump discharge on diesel engines.
