Abstract :
The Poisson´s ratio of a material indicates both its liquid behavior and its incompressibility, the greater and nearer to 0.5 the Poisson´s ratio of a solid material, the better its liquid behavior and its incompressibility. The sealing task for a self-sealing ring is to fully change the medium pressure on its inner cylinder orthogonally into the sealing stress on its end face. Therefore, any soft solid ring can work as a self-energizing seal when compensated for its axial deformation under radial pressure up to the orthogonally deformating degree of a liquid with a Poisson´s ratio of 0.5 by a compensation angle.
