Turbomachine secondary seal assembly

摘要

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.

主权项

1. A turbomachine ring seal assembly, comprising:
a base that extends circumferentially about an axis, the base having an innermost diameter about the axis; and a protruding element extending radially inward and axially forward from the base,
the protruding element having a first sealing surface that contacts a first support to limit movement of a fluid from a first axial side of the base to a second opposite axial side of the base, the contact between the first sealing surface and the first support at a position that is radially inside the innermost diameter of the base,the protruding element having a second sealing surface that contacts a second support to limit movement of the fluid from the first axial side of the base to the second opposite axial side of the base, the contact between the second sealing surface and the second support at a position that is radially inside the innermost diameter of the base,wherein the first sealing surface faces the axis, and the first sealing surface is transverse to the second sealing surface.
