Abstract: A swash pump or turbine includes an inner swash sphere 103 supporting an annular swash plate 103A and having a central aperture 103B. The swash plate is housed within an enclosed pumping chamber 105 enclosed on each side by a fixed cone plate 101, 107 in the shape of a shallow cone so that the plate is enclosed outwardly by the internal surface 106 of a fixed partial sphere housing. The inner swash sphere nutates as the slanted section 102A of the rotatable common drive shaft 102 is rotated within the central aperture 103B whilst maintaining moving sealing lines between the swash plate and the cone plates. The common drive shaft 102 is entirely supported by two bearing elements being (A) a compound bearing supporting the swash plate and having an outer part which is the outer surface of the inner swash sphere slidably supported upon two concave part spherical bearings 109, 109A that are in turn supported against the housing and an inner part being journalled bearings 108 within the central aperture 103B of the inner swash sphere that rotatably support the slanted section of the drive shaft, and (B) a single bearing 110 rotatably supporting the straight section of the common drive shaft against the housing.
