  • Patent number: 10287848
    Abstract: A seal assembly features radially stacked sealing elements separated by a ring shaped structural member with the structural member configured to fold on itself as the inner and outer sealing elements are axially compressed during the setting process. The structural member remains embedded in the outer sealing element when the assembly is set. Seal rings flank the inner and outer sealing element and feature an outwardly facing bevel to contact a conforming bevel shape on extrusion ring assemblies. During axial compression the extrusion rings are pushed out with the seal rings and then the inner and outer sealing elements are axially compressed as the structural member's ends come together and its middle folds. The structural member creates gaps to allow fluid to escape during setting.
