Abstract
An axial piston fluid engine having single-acting cylinders incorporating swivel-joint attachment of the cylinders to rotary control valves wherein straight-line piston movement is established for the elimination of side forces on the pistons. The pistons and the control valves are operatively connected to a common wobble drive member and arranged in geometry of lever positions to coactively time the drive fluid into and out of the cylinders intermittently.
