<p>A turbomachine (2) includes a compressor (4) provided with a casing (12) having an inner surface (14) defining a flow path (18). At least one blade (24, 25, 26, 27, 28) is rotatable within the flow path (18). The at least one blade (24, 25. 26, 27, 28) includes a tip portion that is spaced from the inner surface (14). At least one patch ring segment (46, 47, 48, 49) is mounted (60) to the inner surface (14) of the casing (12). The at least one patch ring segment (46, 47, 48, 49) includes a body (80) having a first end (82) that extends to a second end (83) through a surface portion (84). A first wall member (90) extends from the first end (82) and a second wall member (92) extends from the second end (83). The first and second wall members (90, 92) include in-turned sections (94, 96) that define a C-shaped (99) cross-section of the at least one patch ring segment (46, 47, 48, 49) .</p> |
