<p>An axial piston fluid pumping apparatus in which wobble pistons (46) are rigidly connected to arms (45) of a nutating plate (40) that is mounted on a bearing (43) which is mounted on a drive shaft (14). The axis of the bearing is at an acute angle to the axis of the shaft. The wobble pistons (46) move within cylinders (20) whose bores (22) are disposed about the axis of the shaft. The motion of the pistons (46) is in three dimensions within the bores (22).</p> |
