Abstract
An orientation agnostic ring seal includes an annular body defining an axial hole therethrough for fluid passage in an axial direction and having a radial plane that is perpendicular to the axial direction. Both axial sides of the ring seal include a deformable annular protrusion extending from the annular body in an axial direction to a first apex, which is configured to deform upon engagement with a first planar sealing surface, and a first seal ring engagement surface configured to engage a first annular rounded sealing ring. So configured, the ring seal can seal two different types of flow components regardless of its orientation.
Claims34
A ring seal comprising:
- an annular body defining an axial hole therethrough for fluid passage in an axial direction, the annular body having a radial plane perpendicular to the axial direction;
- a first sealing surface on a first axial end of the annular body, the first sealing surface including a first deformable annular protrusion extending from the annular body in an axial direction to a first apex, the first deformable annular protrusion configured to deform upon engagement with a first planar sealing surface, the first sealing surface further including a first seal ring engagement surface configured to engage a first annular rounded sealing ring;
- a second sealing surface on a second axial end of the annular body opposite the first axial end, the second sealing surface including a second deformable annular protrusion extending from the annular body in an axial direction to a second apex, the second deformable annular protrusion configured to deform upon engagement with a second planar sealing surface, the second sealing surface further including a second seal ring engagement surface configured to engage a second annular rounded sealing ring.
A ring seal for sealing opposing flow component sealing surfaces defining a fluid flow path, the ring seal comprising:
- an annular seal body defining an axial hole for fluid passage in an axial direction;
- and
- a first sealing surface and second sealing surface on opposing axial ends of the annular seal body;
- the first sealing surface including a first annular extension extending from the annular seal body in a first axial direction to a first apex, the first annular extension comprising a first extension surface and a second extension surface extending in opposite directions from the apex back toward the annular sealing body, the second extension surface having a steeper slope to the apex than the first extension surface, the first annular extension configured to deform upon engagement with a planar surface to form a fluid tight seal, the first extension surface being configured to engage an annular rounded sealing ring to form a fluid tight seal.

A ring seal comprising:
- an annular body defining an axial hole for fluid to flow therethrough in an axial direction;
- a first sealing means on a first axial end of the annular body for forming a fluid tight seal of a first type upon engagement with a first type of sealing surface and for forming a fluid tight seal of a second type upon engagement with a sealing surface of a second type;
- a second sealing means on a second axial end of the annular body opposite the first axial end, the second sealing means for forming a fluid tight seal of the first type upon engagement with the first type of sealing surface and for forming a fluid tight seal of the second type upon engagement with the sealing surface of the second type.
A metal seal comprising:
- an annular body defining a fluid passageway therethrough in an axial direction;
- a first sealing surface on an axial end of the annular body, the first sealing surface comprising an annular extension protruding from the annular body in an axial direction, the annular extension including a first extension surface and a second extension surface extending from the annular body at least in part in the axial direction to an apex, the second extension surface having a steeper slope to the apex than the first extension surface;
- wherein the first sealing surface is capable of forming a fluid tight seal between the annular body and a generally flat surface when the sealing surface is forced against the surface, the annular extension being deformable to cause the first extension surface to engage the generally flat surface;
- wherein the sealing surface is further capable of forming a fluid tight seal between the annular body and an annular sealing ring when the first sealing surface is forced against the annular sealing ring, the annular sealing ring engaging an annular portion of the sealing surface radially inward of the apex of the annular extension.
