An axial piston fluid pumping apparatus is disclosed in which wobble pistons are rigidly connected to arms of a nutating plate that is rotatably mounted on a bearing which is mounted on a drive shaft. The axis of the bearing is at an acute angle to the axis of the shaft. The wobble pistons move within cylinders whose bores are disposed about the axis of the shaft. The motion of the pistons is in three dimensions within the bores.
