Abstract
A bearing arrangement for a wobble plate piston pump includes first, second, third, and fourth bearing assemblies. The first and second bearing assemblies support the drive shaft portion for rotation within the housing about the central longitudinal axis, while the third and fourth bearing assemblies support the load plate for rotation relative to the offset shaft portion of the shaft. The second bearing assembly is distally disposed from the first, the third disposed distally to second, and the fourth disposed distally to third. The fourth bearing assembly is the most distally disposed bearing assembly along the shaft.
