In this case the volume required driving piston "B" is the same as the volume displaced in piston "A". The pressure of the fluid in piston "B" is very slightly higher than the pressure of the fluid displaced from piston "A". The work potential relationship of the two fluid volumes is linear. NEW CONSIDERATIONS The accepted facts from the Laws of Thermodynamics in the previous part of this paper are the basic building blocks to understand the operation of the hydraulic motor. There is one significant alteration to the arrangement of piston "B". It is rotated forty-five degrees, hinged at its walls and anchored at two points to make a different piston, "B2", as in FIGURE 4 (Page 13.294). This arrangement allows piston "B2" to expand in a diamond shaped form with piston "B2's" external force, the total of four moving walls, culminating at the tip connected to piston "A". The face area of each of piston "B2's" walls is equal to the boundary face of piston "A". This relationship assures that when piston "B2" expands to displace the fluid in piston "A", the amount of fluid required causing movement in piston "B2" will always be less than the volume of fluid displaced from piston "A". The volume displacement relationship of piston "A" and piston "B2" is NOT linear. This relationship allows a lesser volume of fluid to displace a greater volume of fluid for the same linear travel. The larger volume of displaced fluid in piston "A" has to attain a pressure equal to or greater than the pressure of the fluid in piston "B2" in order for the hydraulic motor to function. This is achieved, as the force at the tip of piston "B2" is greater than the force applied to any one of piston "B2's" four equal walls. The boundary area of piston "A" is equal to each wall of piston "B2". Our experiments indicate that there is a force advantage from zero degree expansion to about twenty-two degree expansion. The power gain starts in the range of fifteen to twenty percent and decreases to zero percent at about twenty-two degree rotation. The net result of these considerations is that a smaller volume of fluid at a lesser pressure can displace a larger volume of fluid at a higher pressure. A circuit has been developed, using this fact, to build a machine that runs itself with no energy input other than the initial start. The machine can be opposed to extract a percentage of the surplus power generated in each cycle while the machine continues to run. 13.292
