  "textContent": "A fuel injector-engine component assembly (20) includes an engine component (26) with a stepped bore (36) defined along an axis (30) and having a stepped bore stop surface (37) facing axially upward. A fuel injector (24) extending along the axis (30) is disposed in the stepped bore (36) and includes a fuel injector stop surface (35) facing axially downward and axially opposing the stepped bore stop surface (37). An isolation ring (28, 128, 228, 328, 428, 528, 628, 728, 828) is disposed between the engine component (26) and fuel injector stop surfaces (35) for axially isolating the fuel injector (24) from the engine component (26). The isolation ring (28, 128, 228, 328, 428, 528, 628, 728, 828) includes a rigid support member (44, 144, 244, 344, 444, 544, 644, 744, 860, 862, 968) for limiting the axial motion of the engine component (26) and fuel injector stop surfaces together (35). The isolation ring (28, 128, 228, 328, 428, 528, 628, 728, 828) also includes a resilient and compliant isolation member (46, 146, 246, 346, 446, 546, 646, 746, 846, 946) located axially between the engine component (26) and fuel injector stop surfaces (35) to provide acoustic and thermal isolation between the fuel injector (24) and the engine component (26) below a predetermined pressure of the fuel injector (24).",
