Abstract:
Device for sealing an annular gap between two planar sealing surfaces of machine parts, with the aid of a ring which rests in contact with said two planar sealing surfaces; said device comprising an elastic ring (7) made of a very strong material, and by means of a pressing device for deforming said ring, a portion (12) of said ring (7) projecting beyond the sealing surfaces is deformed such that said portion (12) becomes arched for sealing said gap or stretches back out of an arched state for canceling the gap sealing, and that said ring (7) in the arched state rests in contact on each of the two planar sealing surfaces (8,9) in the form of an annular line for sealing said annular gap; and wherein said ring (7) in a tension-less state is a planar ring and which through the impression of force becomes arched on its margin projecting beyond the sealing surface.
