SUMMARY -1- The equation W = PV defines fluid performance regarding conventional piston actuators. The work input for every .5” of the example conventional piston actuator’s travel requires 29.87in/lb of work. The input work matches the output work of 29.87 in/lb. The relationship is linear. -2- The equation W = PV does not define fluid performance regarding diamond-shaped actuators. The two example .5” travel segments of our model produced identical work output of 29.87 in/lb, but their work input was different, being 24.38 in/lb and 25.48 in/lb. Both the volume and pressure were different for each travel segment. In this case W = W; however, PV for the first segment of travel ≠ PV for the second segment of travel. WORK SUMMARY OF EXAMPLE ACTUATORS ACTUATOR STYLE TRAVEL RANGE WORK RELATIONSHIP CONVENTIONAL PISTON ANY .5” OF DRIVE WORK IN = WORK OUT (29.87 in/lb) (29.87 in/lb) DIAMOND-SHAPED .5” (1.25” TO 1.75”) WORK IN ≠ WORK OUT (24.38 in/lb) (29.87 in/lb) DIAMOND-SHAPED .5” (2.00” TO 2.5” ) WORK IN ≠ WORK OUT (25.48 in/lb) (29.87 in/lb) -3- The diamond-shaped actuator achieves more work relative to a conventional piston actuator with identical fluid input, regarding both pressure and volume. This occurs only during the first portion of the diamond-shaped actuator’s travel. -4- The diamond-shaped actuator is more efficient than the conventional piston actuator, at varying magnitudes, depending on the angle variation of the diamond-shaped actuator’s walls. -5- This is the main corner stone regarding the patented invention “DIAMOND-SHAPED FLUID POWERED LINKAGE, SYSTEM AND ENGINE”. The efficiency differential produces a work differential, allowing the diamond-shaped actuator to attain its complete source of fluid via pumping the fluid from the conventional piston actuator. The diamond-shaped actuator expends approximately 85% of its work potential generating the total fluid requirement of that action. The diamond-shaped actuator experiences a surplus work potential of approximately 15% after generating its own total fluid requirement relating to each stroke. 13.271
