The question now is: “What is the counter force requirement to displace fluid from a pressurized cylindrical actuator?” The physical model, presented in the photograph on this page, demonstrates that <4% greater counter force is required, forcing fluid from a cylindrical actuator. The diamondshaped actuator develops >15% greater counter force based on investigations via scientist/engineers. When the relationship illustrated in FIGURE 5 is employed, with the appropriate control system, the diamond-shaped actuator can produce its own source of pressurized fluid with >11% power potential remaining in each stroke. PHYSICAL MODEL USED IN DETERMINING THE FORCE DIFFERENTIAL REQUIRED, DISPLACING FLUID FROM AN ACTUATOR, WHEN OPPOSED BY A MORE POWERFUL ACTUATOR. The control drawing relating to the system in the above photograph is on page four. ACT1 ACT2 PB2 PB1 RC1 RC2 BR1 PT2 PT1 GS1 PRV1 BEHIND GAUGE PRV2 CALIPER 13.263
