🔍 Key Concepts

• Radial piston hydraulic pump/motor construction in the illustration (reaction ring/rotor, cylinder block, pistons, pintle valve) • How eccentricity (off-center position) between two circular parts changes piston stroke and therefore flow rate and direction • Difference between changing pump geometry vs. changing prime mover speed/direction

💭 Think About

• Look at how the pistons would move if the cylinder block center and reaction ring center were perfectly aligned. Would there be any piston stroke and fluid displacement? • If you slowly shift one circular component off-center from the other, what happens to the length and direction of each piston’s stroke as the assembly rotates? • Which choice involves changing the internal geometry of the pump itself, rather than just changing the driving motor’s speed or throttling the outlet?

✅ Before You Answer

• Identify which option talks about eccentricity or off-center positioning of parts clearly shown in the illustration (reaction ring and cylinder block). • Confirm which method would allow both reversal of flow direction and variation of flow quantity without wasting power across a throttle valve. • Eliminate any answers that depend only on prime mover speed or throttling, since those do not use the variable-displacement feature shown in the drawing.
