🔍 Key Concepts

• Hydraulic cylinder cushioning at the end of piston travel • The role of flow restriction vs. check valves in controlling speed • How an adjustable needle valve differs from fixed design features

💭 Think About

• When a piston nears the end of its stroke, what actually slows it down: blocking flow, redirecting flow, or changing pressure? • Which component in the options can be adjusted during operation or maintenance to increase or decrease the cushioning effect? • Which parts are fixed by design and which are meant to fine‑tune the system’s behavior?

✅ Before You Answer

• Identify which option describes an adjustable flow restriction rather than a fixed passage or shape. • Decide which component directly affects how fast oil can escape from the cylinder at the end of the stroke. • Confirm which device is used in practice when a mechanic wants to increase or decrease end‑of‑stroke cushioning without changing hardware.
