Abstract
An exemplary turbomachine secondary ring seal assembly includes a base portion that extends circumferentially about an axis and a protrusion extending from the base portion toward the axis. The protrusion has a sealing surface that contacts a support to limit movement of a fluid from a first axial side of the base portion to a second opposite axial side of the base portion. The sealing surface faces the axis. The sealing surface may also face in a radial direction.
