HYDRAULIC DISPLACEMENT MOTOR FUNDAMENTAL SCIENCE The foundational point of the following discovery establishes that a diamond-shaped actuator can produce 100% of it’s fluid requirements, as illustrated in FIGURE “D”, forcing the fluid from a standard piston, while using only 85% of its work potential. The remaining 15% work potential can be captured as free work. No other energy source is required. This paper develops an understanding of this fact. 13.233 FIGURE “A” illustrates a standard piston with a constant fluid source at 10 PSIG pressure, applied to the piston’s 10 in² boundary face, resulting in 100 pounds of force applied to the piston’s shaft. The travel distance is one inch, consuming 10 in³ of fluid.

A 102-pound force is applied to the shaft, over-powering the 100 pounds of force generated by the pressurized fluid. The shaft travels one inch forcing 10 in³ of pressurized fluid from the standard piston back into the cushion tank at 10 PSIG pressure.
