EXECUTIVE SUMMARY The fluid equation WORK = PRESSURE x VOLUME (W = PV) applies to the linear fluid performance regarding conventional piston actuators. In these cases work input = work output (WI = WO). The fluid equation WORK = PRESSURE x VOLUME (W = PV) does not apply to the non-linear fluid performance regarding diamond-shaped actuators. In the initial stages of the diamond-shaped actuators’ stroke, work input is less than work output (WI < WO). Many engineer/scientists have tested the physical model concluding this fact. Diamond-shaped actuators are more efficient than conventional piston actuators in the early stages of the diamond-shaped actuators’ stroke.

The remaining 15% of the diamond-shaped actuator’s work potential may be extracted, addressing work requirements other than producing its own fluid source. 15% net work achieved = ((force “X” – force “Y”) x travel) VC1 (volume change one) < VC2 ( volume change two) FLUID FLOW (TYPICAL) VC2 13.267
