Abstract
A high pressure axial piston pump displaces high pressure, high volume fluid into a 1994-2003 7.3 liter power stroke or T444E International engine. A pump housing forms a central borehole, an intake port, and two discharge ports angled about 122 degrees from each other and in fluid communication with engine. A drive shaft rotates a cylinder block about an axis of rotation. A cam is tilted at an angle relative to axis of rotation. Multiple pistons, having a cam end and a block end, reciprocate through cylinder block. The cam end is constrained to follow surface of cam. When pistons move proximally to tilted cam, the block end restricts intake of fluid, and cam end enables discharge of fluid. When pistons move distally from tilted cam, the block end enables intake of fluid, and cam end restricts passage through discharge ports. The pump is fabricated from billet aluminum material.
