Abstract: A fluidic machine operable primarily as a pump or a fluid motor having primary and secondary vaned members hinged together within a spherical pump chamber to define four intake and exhaust spaces of varying volumes. A tracking mechanism which includes an annular raceway forces the secondary member to rotate about an oblique axis as the primary member rotates about a primary axis.

The pump chamber is provided with four ports in positions which are coordinated with the tracking mechanism to ensure one port is in fluid communication with each space throughout each pivotal stroke of the secondary member.
