Abstract
A device for use with a retrievable bridge plug (,) comprising an upper packer element (,) and a lower packer element (,). The upper element (,) is connected to an upper link (,), which can rotate around a first pin (,). Upper link (,) is rotatably connected to a lower link (,) by a second pin (,). Lower link (,) can rotate around a third pin (,). An angle (&agr;) is formed between the longitudinal axis of the bridge plug and a line extending through the first pin (,) and the second pin (,), and correspondingly through the second pin (,) and the third pin (,), which is greater than zero when upper link (,) and lower link (,) is drawn. Upper link (,) and lower link (,) are arranged for, at setting, to expand radially by compression of upper packer bracket (,) against lower bracket (,), for forming a mechanical barrier for upper packer element (,) and lower packer element (,).
