Claim:
1. A differential fluid transmission comprising: a fluid; a series of piston and cylinder sets wherein said pistons are connected to a crankshaft that rotates as said pistons traverse back and forth within said cylinders; one multi port input valve per each of said piston and cylinder sets in fluid connection with said piston and cylinder, said input valve having one outlet port and multiple inlet ports, wherein the admission of a fluid into said piston and cylinder set passes through said outlet port; one multi port output valve per each of said piston and cylinder sets in fluid connection with said piston and cylinder, said output valve having one inlet port and multiple outlet ports, where the ejection of said fluid from said piston and cylinder passes through said inlet port; a flow controller in operational contact with said input valve and said output valve of a single piston and cylinder set that synchronizes the admission and ejection of said fluid into and out of said piston and cylinder set through an isolated inlet path connected to a dedicated port of said multi port inlet valve attached to said piston and cylinder set; a control system in operational contact with all said input valves and all said output valves of all said piston and cylinder sets that operates the opening and closing of said multiple outlet ports on said input valves and said multiple inlet ports on said outlet valves; wherein said fluid is provided by at least one fluid energy source to the multiple ports of said multi port input valve for admission into said piston and cylinder set; wherein said fluid from said piston and cylinder set is directed through the multiple ports of said multi port output valve to a fluid powered equipment; and wherein the admission and ejection of said fluid into and out of said piston and cylinder sets rotates said crankshaft to store energy as torque and to distribute said energy to said fluid powered equipment and wherein said fluid powered equipment has a common output path for the flow of said fluid back to said fluid reservoir.
