Abstract

A 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. An axial side of the ring seal includes deformable annular protrusions extending from the annular body in an axial direction to first and second apexes, which are configured to deform upon engagement with a first planar sealing surface and define a trough therebetween to engage a first annular rounded sealing protrusion or ring. So configured, the ring seal can seal two different types of flow components.

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.

Abstract

A ring seal for sealing opposing flow component sealing surfaces defines a fluid flow path that is suitable for applications such as a semiconductor manufacturing modular gas delivery system. The ring seal includes an annular extension in the form of a modified “delta” extending from one or both sealing surfaces of the ring seal. The modified “delta” extends to an apex or point above the ring seal's sealing surface. First and second extension surfaces extend in opposite directions from the apex back toward the ring seal's sealing surface. In one aspect, the first extension surface defines a ridge where the slope of the first extension surface changes to decline faster to the ring seal's sealing surface. In another aspect, the apex is located within the annular extension closer to the axial hole than to an outer radial diameter of the annular seal body.

• F16J 15/08 - Sealings between relatively-stationary surfaces with solid packing compressed between sealing surfaces with exclusively metal packing

Abstract

An example sealing system includes a retainer for a gasket wherein the retainer protects the polished sealing surface of the seal gasket from scratches before assembly by suspending the gasket inside the retainer, regardless of orientation. A gap in the circumference of the retainer allows the retainer to flex open for insertion of the seal gasket. A small chamfer on the inner diameter of the retainer aids the insertion of the seal into the retainer. The gap in the circumference of the retainer also allows the retainer to compress to a smaller circumference for a tight fit inside the sealing counterbore. A groove in the inner diameter of the retainer includes a protruding portion for the seal to engage. The depth of this groove is configured to provide some clearance inside the retainer for the protruding edge of the seal during a complete compression of the retainer.

Abstract

The ring seal and retainer assembly includes an annularly shaped ring seal defining a radial inner surface, a radial outer surface, first and second axial end surfaces and a central bore for fluid or gas passage. A retainer is provided for affixing and positioning a ring seal in a sealing assembly. The retainer includes a circular sidewall sized and positioned to engage and cover the ring seal's radial outer surface. The retainer includes an arcuate flange which extends at one of the retainer's axial extremities to form a concave interior and a convex exterior. Preferably, the arcuate flange extends outwardly to increase the retainer's radius and the arcuate flange is sized to compressibly engage the interior sidewall of the component block's counterbore.
