Definitions

  • the present invention relates to seals, often referred to as gaskets, for making a fluid or gas tight joint between opposed mating surfaces. More
  • the present invention relates to retainers for positioning seals between opposed mating surfaces.
  • Ring seals are typically annularly shaped, defining an axially aligned hole for gas or fluid passage, two axially opposed end surfaces, a radial inner surface and a radial outer surface.
  • the most simplistic ring seal includes planar end surfaces and smooth circular radial inner and outer surfaces which define the inner diameter (ID) and outer diameter (OD) of the ring seal.
  • An additional commonly used ring seal is circular and has a radial cross- section of a "C" shape. These "C seals" are constructed with the open side of the C construction facing the center of the ring such as described in U.S. Patent No.
  • V seals which are also circular, but instead of having a “C” cross-section, the V seal has a “V” cross- section with the low point of the V constructed to point either inwardly or outwardly towards the center of the seal.
  • seals in the art include “Z seals” and simple “O rings”.
  • the above described ring seals often include a recessed sealing surface.
  • the typical ring seal 1 includes an annular body configuration and a circumferential groove 15 formed into the ring seal's outer radial surface 13.
  • the ring seal may include a recessed sealing surface 19 formed into each of the axial end surfaces.
  • the opposed mating surfaces 17 of the sealing assembly engage and form an air or fluid tight seal at the ring seal's sealing surface.
  • the sealing surface is recessed to protect the surface from becoming damaged during handling. For example, ring seals having planar surfaces often become scratched when placed on flat surfaces due to dirt or metal shavings scratching the ring seal's sealing surface.
  • the ring seal's sealing surface is recessed so as to not come into contact with debris prior to assembly within a sealing assembly.
  • ring seals having recessed sealing surfaces are expensive to manufacture and the recessed sealing surfaces are very difficult to polish.
  • the parallelism is extremely critical between two recessed sealing surfaces. Usually, special machining equipment must be used to achieve the parallelism requirement.
  • Retainers are often used to hold and position a ring seal in place between two opposed mating surfaces. Retainers have been constructed in various forms. For example, U.S. Patent No. 5,340,170 describes a retainer for positioning a gasket in a pipe joint.
  • the retainer includes a cylindrical sidewall, an inwardly extending edge for engaging a ring seal and a plurality of claws for grabbing a pipe.
  • U.S. Patent No. 5,423,580 discloses a retainer having a semicircular sidewall for grasping the outer edge of a ring seal and extremity of a pipe. Moreover, additional retainer arrangements are disclosed in U.S. Patent Nos. 4,552,389; 4,650,227; and 4,838,583.
  • FIG. 1 - 4 A typical prior art ring seal and retainer assembly is shown in Figs. 1 - 4.
  • the ring seal 1 includes an annular body element 3 forming an axially aligned hole 5 for liquid or gas passage.
  • the ring seal includes a radial inner surface 1 1 , a radial outer surface 13, a first axial end surface 7 and a second axial end surface 9.
  • the radial outer surface 13 has been constructed with a curved recess forming a "C" shape.
  • Additional constructions for the ring seal have included "V seals" and "Z seals".
  • prior art ring seals have included a radial outer surface having a groove 15.
  • the groove has been constructed with squared planar surfaces, or constructed with curved surfaces.
  • the prior art ring seals have included a recessed sealing surface 19 formed on each of the axial end surfaces.
  • a retainer may be obtained from a single loop of a coil spring, which is then formed into a circular band.
  • the coil retainer is positioned within the ring seal's circumferential groove so that the outer edge of the coil projects outwardly beyond the edge of the ring seal.
  • the opposed mating surfaces include a fitting including a recess sized and positioned for receipt of the coil retainer's edge. Once press fit into place, the retainer is restrained from inadvertent movement.
  • Figs. 5 - 7 illustrate retainers shown in U.S. Patent Publication No.
  • retainers which are circular in shape, and include a sidewall sized and positioned to cover and engage a ring seal's radial outer surface.
  • the retainers' circular sidewall projects axially beyond the ring seal's axial end surfaces.
  • the retainer extends axially beyond one or both of the ring seal's axial end surfaces to provide an arcuate flange having a concave interior and a convex exterior.
  • the arcuate flange extends radially outward from the retainer's circular sidewall so as to provide the ring seal and retainer assembly with a substantially increased radius sized to reside in a press-fit arrangement within a counterbore formed within one of the opposed mating surfaces of a component block.
  • U.S. Patent Publication No. 2008/0191426 also illustrates retainers having one or more circumferential ridges sized and positioned to project inwardly from the retainer's circular sidewall into the ring seal's circumferential groove.
  • the circumferential ridge projects into the ring seal's groove to inhibit the annular retainer from inadvertently being dislodged or disengaged from the ring seal.
  • the above-described retainers all suffer from significant disadvantages.
  • the coil retainer and sharp edges of the ring seal are prone to scratching, or otherwise harming, the opposed mating surfaces. This can impede the ring seal's ability to provide a gas or fluid tight seal.
  • ring seals having recessed sealing surfaces are expensive to manufacture and the parallelism requirement between the two recessed sealing surfaces presents a high risk of leakage.
  • the retainer described in U.S. Patent No. 5,340,170 is capable of use only with a ring seal of an unusual construction.
  • the retainer disclosed in U.S. Patent No. 5,423,580 also does not protect the edge of a ring seal from undesirably scratching one of the opposed mating surfaces.
  • the retainers disclosed in U.S. Patent Publication No. 2008/0191426 can undesirably decouple from retainers meant to be held in place.

  • it would be desirable to provide an improved ring seal and retainer assembly which provides protection against damage to a ring seal's sealing surfaces, while not being susceptible to scratching or otherwise marring the opposed mating surfaces prior to forming an air-tight or gas-tight seal.
  • Still an additional desirable feature for a retainer would be that it adequately hold ring seals without ring seals inadvertently decoupling from the retainer.
  • the present invention addresses the aforementioned disadvantages by providing an improved ring seal and retainer assembly.
  • the ring seal is annularly shaped having an axially aligned hole for gas or fluid passage.
  • the ring seal further includes a radial inner surface, a radial outer surface and first and second axial end surfaces.
  • the retainer is circular in shape, and includes a sidewall which is sized and positioned to cover, though not necessarily engage the ring seal's radial outer surface. The sidewall protects the ring seal's radial outer surface from becoming damaged prior to assembly within a sealing assembly, and protects the opposed mating surfaces from being damaged by preventing the ring seal's outer edge from scratching the opposed mating surfaces during assembly.
  • the retainer's circular sidewall projects axially beyond the ring seal's axial end surfaces.
  • the protruding extremities of the circular sidewall protect the ring seal's axial end surfaces during storage and transportation, thereby eliminating the need for the ring seal having a recessed sealing surface.
