发明名称 anel calibrador expansível.
摘要 A gage ring assembly to provide support to an anti-extrusion containment ring in a packer device including a compression ring and a plurality of interlocking arcuate segments which form a substantially unbroken support wall when in a set condition. A first set of segments each have a wedge-shaped body that is wider at a proximal axial end than it is at its distal axial end. A second set of segments preferably each have a wedge-shaped body wider at its distal axial end than it is at its proximal axial end.
