A rotational mechanism which consists of a circular armature fitted with a plurality of radial vanes which rotates within a stationary, cylindrical, containment structure with a circular bore. The rotational armature is concentrically installed on a rotational shaft which passes through the axial ends of the containment structure and which is supported by low friction rotational bearings such as to rotate on an axis which is parallel to, but radially separated from, the axis of the containment cylinder. The axial ends of the shaft provide the interface with external mechanically dynamic systems. The armature is a hollow cylinder which incorporates a plurality of uniformly distributed radial slots each of which extends through the annulus. The axial slots are each sized such as to provide annular support for a radial vane but allow relative sliding movement of the vane in axial and radial directions. The radial vanes are radially and axially constrained at each end such by means a rotating vane end constraint assemblies. The vane end constraint assemblies are supported by low friction rotational bearings such as to rotate on an axis which is concentric with the axis of the containment cylinder. The vane end constraint assemblies each consist of a disk with an axially extended rim, an axial compression spring, and a wear ring. The axially extended rim of the said disk radially constrains each vane such that the outermost peripheral edge of the vane is in close proximity to, but not in contact with, the inside surface of the containment cylinder. The cavity formed by the axial face and the axially extended rim of the disk accommodates the axial spring and the wear ring.
