  • Patent number: 10989305
    Abstract: Floating seal assemblies having a seal element, a support band, and at least two loading springs that produce different spring forces to apply different sealing loads at the first and second sealing flanges of the seal element. The seal assembly is without a locking ring to enable the seal assembly to float along an axis of one of the components to be sealed. The different sealing loads allow the seal assembly to grip against one surface to prevent relative rotation and to enable sealing and relative rotation with another surface.

  • Patent number: 10935097
    Abstract: A coil spring for use in a cavity, such as in a groove of a pin, a housing, or both. The cavity can also be part of a seal assembly. The coil spring can have a longitudinal component positioned within the plurality of interconnected coils that runs along the spring coil axis in order to increase rigidity of the coil spring. The longitudinal component applies a load against the coil spring and/or provides restriction against the coil spring taking a shape or size different than that of the coil spring retaining groove.

  • Patent number: 10900531
    Abstract: Spring rings and closed wire loops each can have two ends that are connected. The connected ends can be welded. The connected ends can be aligned for welding by incorporating complementary surfaces so that when joined, the tip at the first end mate to the tip at the second end. The mating can be self-aligning spatially and radially. The spring rings and the closed wire loops can be used in many applications, including in connector applications and seal applications.

  • Patent number: 10801622
    Abstract: Supported face seal assemblies and related methods are disclosed. The supported face seal assemblies have spring energized seal element supported by a backing ring. When the two components are joined, they form an interlocking face seal assembly that is less prone to separate during installation and/or service. The methods disclosed include the steps of forming a spring energized sealing element with a convex outer surface, forming a backup or support ring with a concave inner surface, assembling the sealing element into the inner bore of the backup or support ring such that the concave inner surface accepts a portion of the convex outer surface and the sealing element is retained within the backup or support ring.
