🔍 Key Concepts

• How an internal gear pump moves liquid from suction side to discharge side • The function of the crescent-shaped partition between the inner and outer gears • What happens to liquid trapped between gear teeth as the gears mesh and un-mesh

💭 Think About

• Look at where the crescent is located: does it create more space for liquid, or separate spaces of liquid as the gears rotate? • As the inner and outer gears pass the crescent, what happens to the volume between the teeth on the suction side versus the discharge side? • Which option describes a mechanical function between gears, and which options describe hydraulic side-effects that might or might not actually require a crescent?

✅ Before You Answer

• Identify which option specifically refers to the interaction between the inner and outer gears • Decide whether the crescent’s main job is to act on the liquid directly or to control the gear engagement and clearances • Eliminate any choices that sound like secondary effects (air removal, pulsation smoothing) rather than the primary geometric role of that crescent in the drawing
