The two graphs below illustrate that only 3.53% more counter force is required on a cylindrical actuator’s shaft to force fluid from that pressurized cylindrical actuator. The scientist/engineers’ testing demonstrates that the diamond-shaped actuator’s efficiency advantage over cylindrical actuators is >15%; therefore, produces >15% counter force compared to the opposing cylindrical actuator illustrated in FIGURE 5. The volume of fluid required by the diamond-shaped actuator is less than the volume of fluid it forces from the cylindrical actuator; therefore, the diamond-shaped actuator can generate its own source of pressurized fluid, while having >11% work potential remaining in each stroke. 13.265
