Zusammenfassung:	An axial piston pump has a rotatable input shaft integral with a rotatable swash plate. A non-rotatable cylinder contains a plurality of axially movable pistons having spherical ends extending through the cylinder journaled in slipper assemblies that are in contact with the swash plate. A retainer plate in contact with the slipper assemblies is spring biased to urge the slippers against the swash plate to maintain the swash plate in fixed axial position. The input shaft is journaled only by a sleeve bearing while an annular thrust bearing plate between pump housing and a swash plate axial end allows for swash plate rotation within the pump housing. The swash plate has a cam shaped circumferential edge surface. An auxiliary pump having a prime mover in contact with the cam shaped edge of the swash plate is mounted between the axial ends of the piston pump.
