  • Displacement absorption tunnels for circular beads
    Patent number: 11329296
    Abstract: A plate includes a planar portion and a circular bead, or circular bead seal, that is offset from the planar portion. An axis is substantially perpendicular to the planar portion, and the circular bead arcs about the axis. The axis may be defined by a hole through the planar portion that is substantially surrounded by the circular bead. One or more displacement absorption tunnels is offset from the planar portion and extends radially relative to the axis. Each of the displacement absorption tunnels intersects the circular bead. In some configurations the displacement absorption tunnels may have an arcuate shape, and in some configurations the displacement absorption tunnels may have a trapezoidal shape. A plurality of plates having similar, though not identical, features may be stacked together.
