Abstract
A rotatable drive shaft in the swash pump or turbine for liquids is supported by one bearing at each end. An integrated motor or dynamo uses the same two bearings. The compound first bearing supports a slanted section of the drive shaft placed inside the inner swash sphere, and transfers rotational power to the attached nutatable swash plate. The second bearing confines rotation of the drive shaft in a defined axis. Either one of the bearings is made to prevent axial movement of the drive shaft, preventing swash pump misalignment. A resilient drive, and an immersed pump are described.
