Abstract:
A bearing arrangement 24 for a wobble plate piston pump 10 includes first, second, third, and fourth bearing assemblies 90, 92, 94, 96. The first and second bearing assemblies 90, 92 support the drive shaft portion 70 for rotation within the housing 16, 18 about the central longitudinal axis 74, while the third and fourth bearing assemblies 94, 96 support the load plate 28 for rotation relative to the offset shaft portion 72 of the shaft 26. The second bearing assembly 92 is distally disposed from the first 90, the third 94 disposed distally to second 92, and the fourth 96 disposed distally to third 94. The fourth bearing assembly 96 is the most distally disposed bearing assembly along the shaft 26.
