ABSTRACT:
A fluid pumping apparatus is disclosed in which wobble pistons are rigidly connected to arms of a swashplate that is rotatably mounted on bearings which are mounted on a drive shaft. The axis of the bearings is at an acute angle to the axis of the shaft. The wobble pistons move within cylinders whose bores are parallel to the axis of the shaft. Two or more pistons and cylinders are arranged symmetrically about the shaft axis, and cylinder-piston combinations are mounted at opposite ends of a through shaft.
