AP—7 PUMP

Variable-displacement axial piston machine · 7-cylinder cutaway

ENGINEERING / INTERACTIVE LABORATORY

A rotating barrel.
Seven reciprocating pistons.

The shaft turns the cylinder block while each piston follows the tilted swashplate. Changing its angle alters stroke, displacement and hydraulic output.

Model: stroke = 2R tan(α) · V_rev = 7πr² stroke
Q = V_rev n η_v · T = Δp V_rev / (2π η_m)
Assumed η_v = 0.92, η_m = 0.89. Illustrative, not a certified pump curve.

INLETHIGH PRESSURE

Switch to exploded view to inspect the valve plate, piston shoes and mounting flange. Changes to angle modify every piston’s axial movement, not just a visual gauge.
