Abstract

A fluid damping structure is provided that includes a damper ring. The damper ring includes an annular body, a plurality of fluid check valves (122), and at least one fluid stop (124). The annular body extends circumferentially around an axial centerline, and is defined by a first end surface (88), a second end surface (90), an outer radial surface (92), and an inner radial surface (94). The outer radial surface (92) and the inner radial surface (94) extend axially from the first end surface (88) toward the second end surface (90). The body includes one or more check valve passages (104). Each check valve passage (104) extends axially from an open end (106) disposed at the first end surface (88) inwardly toward the second end surface (90), and is disposed between the inner radial surface (94) and the outer radial surface (92). An inlet aperture (112) extends between each check valve passage (104) and the outer radial surface (92), and an outlet aperture (114) extends between each check valve passage (104) and the inner radial surface (94). Each fluid check valve (122) is disposed in a check valve passage (104). The at least one fluid stop (124) is configured to prevent fluid exit from the open end (106) of each check valve passage (104).
