Abstract: An inlet guide vane assembly for a compressor is provided. The inlet guide vane assembly may include a hub configured to be disposed in an inlet of the compressor, and an inlet guide vane extending from the hub. The inlet guide vane may include a stationary section configured to be coupled with the inlet and a mobile section disposed adjacent the stationary section. The mobile section may include a rod configured to extend through an opening formed in the inlet. The inlet guide vane assembly may also include at least one biasing member disposed about the rod and configured to exert a biasing force on the mobile section to urge the mobile section radially outward.

Abstract: A balance piston seal assembly for a balance piston of a compressor is provided. The balance piston seal assembly may include a balance piston seal, a stationary support, and a gripping assembly disposed between the balance piston seal and the stationary support. The balance piston seal may be configured to be disposed about the balance piston such that an inner radial surface of the balance piston seal and an outer radial surface of the balance piston define a radial clearance therebetween. The stationary support may be configured to be coupled or integral with a casing of the compressor. The gripping assembly may be configured to secure the balance piston seal with the stationary support and to maintain concentricity between the balance piston seal and the balance piston during thermal radial expansion of the balance piston seal relative to the balance piston.
Abstract translation: 提供了一种用于压缩机的平衡活塞的平衡活塞密封组件。 平衡活塞密封组件可包括平衡活塞密封件，固定支撑件和设置在平衡活塞密封件和固定支撑件之间的夹紧组件。 平衡活塞密封件可以构造成围绕平衡活塞设置，使得平衡活塞密封件的内部径向表面和平衡活塞的外径向表面在其间限定径向间隙。 固定支撑件可以被构造成与压缩机的壳体联接或一体。 夹持组件可以被配置为在平衡活塞密封件相对于平衡活塞的热径向膨胀期间将平衡活塞密封件固定在固定支撑件上并且在平衡活塞密封件和平衡活塞之间保持同心度。
