SEALING ARRANGEMENT ABSTRACT OF THE DISCLOSURE The disclosed arrangement is for sealing between two cylindrical bodies with an annular gasket ring in such a way that the seal is established only under conditions of a pre- determined fluid pressure, so that at a lower pressure a flow is permitted across the seal. The ring in its relaxed state has a clearance spacing from the sealing surfaces. It has a radial cross-sectional configuration such that when there is fluid pressure against the ring from one side, it deforms out- wardly to provide the necessary sealing force against the sealing surfaces. The radial cross-section of the ring has a first portion extending along the sealing surface of the outer body and at least one further portion extending in substantially radial manner from the first portion. The deformation takes place by a radial cross-sectional rotation about a torsional axis which is located in the first part of the ring. Various ring and seat configurations are described.
