⚙️ Radial-Piston Pump: Eccentric Cam, Delivery Ripple, Torque and Leakage (2D)

End view of a radial-piston hydraulic pump with an eccentric cam and up to nine pistons, showing which pistons fill and which discharge as the shaft turns. Set the number of pistons, bore, eccentricity, speed, pressure and leakage, and see the delivered flow, the flow ripple, the shaft torque and the volumetric efficiency. Mean flow, ripple, stroke and power balance are checked numerically, with four in-page numerical checks.
