초록 ▼

A dealing device having a body section and an anti-extrusion section is disclosed, the body section being disposed on top of the anti-extrusion section. The body section includes sealing surfaces for enclosures in which the sealing device is located. The anti-extrusion section prevents extrusion of

대표청구항 ▼

An anti-extrusion sealing device for use in an enclosed area subject to force, comprising: an extrudable body section having extrudable material and an upper end, said upper end including a top in contact with the enclosed area force and an inner and an outer sealing surface opposing each other depending downward from said top and contacting the enclosed area and said body section having a lower portion depending downward from said sealing surfaces; an anti-extrusion section having an upper portion and a bottom, said bottom having a bottom surface, said anti-extrusion section in contact at said upper portion to said lower portion of said body section and said bottom surface abutting the enclosed area, said anti-extrusion section serving to resist extrusion forces acting on said sealing surfaces adjacent said anti-extrusion forces acting on said sealing surfaces adjacent said anti-extrusion section, said anti-extrusion section being comprised of a knitted material, at least some of the filaments of said knitted material being metallic in nature, said upper portion having inner and outer radial edges facing the enclosed area and an upper surface having at least a partial V-shape in cross-section between said edges; said extrudable body section having a lower end with a lower portion having a lower surface shaped for reception in said upper surface of said anti-extrusion section upper portion and said sealing surfaces extending radially beyond said edges prior to application of the force; said anti-extrusion section bottom includes a portion below said V-shape upper surface of sufficient axial thickness to permit rotation of said radial edges and said upper surface so that said radial edges contact the enclosed area in response to normal force applied to said upper surface, whereby upon application of force from the enclosed area upon said top, said radial edges rotate into contact with the enclosed area adjacent to said sealing surfaces, forming an anti-extrusion seal for said extrudable material of said sealing surfaces; wherein, said sealing surface of said upper end includes an inner concave central portion and at least one V-shape outer surface, in cross-section, having slanted upper and lower surfaces, which intersect at the apex of the said V; wherein the angle T measured between a first horizontal ray parallel to said base extending from said apex and a second ray extending upward from said lower surface has a range between 20°and 30°.
