Abstract: An annular seal is provided for use in a turbomachine. The annular seal may form a generally rectangular cross-section and may include an outer radial surface forming an outer sealing surface and defining at least one annular groove and a plurality of slots spaced circumferentially about the outer radial surface. Each slot may have an end terminating in the at least one annular groove. The annular seal may also include a first axial sidewall forming a sidewall sealing surface and a recessed portion and a second axial sidewall opposing the first axial sidewall. At least one annular groove and the plurality of slots may be configured to maintain a low pressure environment across at least a portion of the outer radial surface. The second axial sidewall, the recessed portion, and the inner radial surface may be configured to maintain a high pressure environment there across during operation of the turbomachine.
Abstract translation: 提供用于涡轮机中的环形密封件。 环形密封件可以形成大致矩形的横截面并且可以包括形成外密封表面的外径向表面，并且限定至少一个环形槽和围绕外径向表面周向间隔开的多个槽。 每个槽可以具有终止于至少一个环形槽中的端部。 环形密封件还可以包括形成侧壁密封表面的第一轴向侧壁和与第一轴向侧壁相对的凹陷部分和第二轴向侧壁。 至少一个环形槽和多个狭槽可被构造成在外部径向表面的至少一部分上保持低压环境。 第二轴向侧壁，凹陷部分和内部径向表面可构造成在涡轮机操作期间保持横跨高压环境。

Abstract: A bearing assembly support and adjustment system includes an annular support device and an annular adjustment sleeve. The annular support device has a support device outer circumferential surface located about a first axis and a support device inner circumferential surface located about a second axis spaced apart from the first axis. The annular adjustment sleeve has an adjustment sleeve outer circumferential surface located about a third axis and an adjustment sleeve inner circumferential surface located about a fourth axis spaced apart from the third axis. The annular adjustment sleeve is coupled to the annular support device with the adjustment sleeve outer circumferential surface located immediately adjacent the support device inner circumferential surface.

Abstract: A seal apparatus (58) for a casing (12) of a turbomachine (10). The seal apparatus (58) may include an annular body (60) having first (66) and second (88) annular body portions and an appendage (94). The second annular body portion may extend axially from the first annular body portion (66) and may have an outer annular surface (88) radially offset from an outer annular surface (72) of the first annular body portion (66). The appendage (94) may extend axially from the first annular body portion (66) and may have an outer annular surface (96) and an inner annular surface (98). The inner annular surface (98) of the appendage (94) and the outer annular surface (88) of the second annular body portion (86) may define an annular cavity (116) therebetween, and at least a portion of the appendage (94) may be configured to be displaced radially outward in order to maintain contact with first (20) and second (22) inner cylindrical surfaces of the casing (12) during radial expansion of the casing (12).

Abstract: A shaft of a compressor may include a first shaft section defining a first cavity axially extending therein and a second shaft section defining a second cavity axially extending therein. A plurality of inlet holes may be defined on an outer surface of the first shaft section, and a plurality of outlet holes may be defined on an outer surface of the second shaft section. The plurality of inlet holes may be in fluid communication with the first cavity and the plurality of outlet holes may be in fluid communication with the second cavity. The first cavity and the second cavity may form a passageway fluidly coupling the plurality of inlet holes and the plurality of outlet holes.
