🔍 Key Concepts

• Study the internal parts: the check ball, spring, and oil passage shown in the illustration. • Think about which device in an engine valve train automatically keeps zero valve lash (no clearance) as parts expand and contract with temperature. • Compare a pressure‑relief valve (how many flow paths, where the spring sits) with a valve‑train component that rides between the cam and the valve stem.

💭 Think About

• Ask yourself: Does this device look like something mounted in a piping system to control flow, or something that would sit in the engine’s valve train under the rocker arm or over the cam? • How many directions can fluid actually flow here? Does the drawing clearly show three separate flow outlets, or is it mainly a single feed with a check ball to trap oil? • Which of the choices would require an internal plunger with a trapped oil chamber and spring to maintain constant length under changing load?

✅ Before You Answer

• Verify whether the component body is cylindrical like a tappet/lifter rather than a flanged line valve body. • Check if the ball and spring are arranged to trap oil and create a solid but slightly movable column, typical of an automatic lash‑taking device. • Confirm whether there is any clear valve stem or spring cap shape, or if instead you see an enclosed hydraulic unit that would be hidden inside the engine.
