1. A device for generating a radial displacement of a mechanical part disposed within the device, said device comprising:
an annular frame (12) extending longitudinally around an axis X-X, a swiveling ring (11), and an internal ring (13), said frame (12), swiveling ring (11) and internal ring (13) interacting to form two nested ball joint connections with respective centers A and B, said centers A and B being disposed on said axis X-X when said device is in neutral position and separated by a distance ε, one or more actuators (2) integrated with said frame, each of the one or more actuators being parallel to and radially displaced from the axis X-X, one or more push rods (3), each of the one or more push rods being associated with one of the one or more actuators; a guide ring (4) integrated with said frame, said guide ring (4) having one or more bidirectional planar links (e) into which the one or more push rods (3) are received, wherein operation of at least one of the one or more actuators to put the device in an activated position displaces the associated push rod within one of the one or more bidirectional planar links to bear on the swiveling ring (11) and causes the swiveling ring (11) to rotate relative to the frame (12) and the internal ring (13) to be displaced radially away from axis X-X within the frame such that center B no longer lies on the axis X-X, whereby the mechanical part is radially displaced, the mechanical part being associated with internal ring (13). |
