  • Publication number: 20230332721
    Abstract: A gasket bridge assembly includes a gasket bridge defining a first circumferential bridge end, a second circumferential bridge end opposite the first circumferential bridge end, and an arcuate body arcing between the first and second circumferential bridge ends, wherein the gasket bridge comprises: a first anti-slip feature at the first circumferential bridge end; a second anti-slip feature at the second circumferential bridge end; and a third anti-slip feature disposed between the first and second circumferential bridge ends; and a gasket assembly disposed radially inward of the gasket bridge, wherein each of the first, second, and third anti-slip features extend radially inward and dig into an outer sealing surface of the gasket assembly to prevent movement of the gasket assembly relative to the gasket bridge.

  • Patent number: 11255473
    Abstract: Example aspects of a gasket bridge for an end ring assembly and a method for using an end ring assembly are disclosed. The gasket bridge can comprise an arcuate body defining an inner surface, an outer surface, a first bridge end, and a second bridge end, the arcuate body defining a bridge radius of curvature; a first ramp extending from the first bridge end; a second ramp extending from the second bridge end; and a projection extending from the inner surface.
