Abstract
An annular device generates essentially radial displacements of a shaft disposed within the device includes a frame, a swiveling ring and in internal ring with which the shaft is associated. Actuators and guide rods within the housing cause the swiveling ring to rotate relative to the frame and the internal ring to be displaced radially such that a shaft associated with the internal ring is radially displaced. The device is useful for drilling trajectory control devices.
