SUMMARY • The formula W = P∆V applies the conventional hydraulic piston. • The formula W ≠ P∆V applies to the Diamond-Shaped Actuator. • Scientists who tested the actual physical models confirm the mechanical advantage of the Diamond-Shaped actuator at +15% over the conventional piston. • The mechanical advantage of < 4% produces a work advantage in favour of the Diamond-Shaped Actuator. • The Diamond-shaped Actuator generates its total fluid requirement by pumping the fluid from a conventional piston with > 11% mechanical advantage remaining. ( +15% - 4% ≥ 11%) • A reciprocating machine can be produced which produces enough work to run itself and deliver surplus work externally, suiting other requirements. • The machine will only stop if commanded to do so by blocking fluid flow, depressurization or mechanical failure. • A control circuit is presented on pages 13.255 to 13.257 and page 13.254 illustrates the mechanical advantage of the Diamond-Shaped Actuator. • Please send questions or comments.
