    摘要: Butterfly valves assemblies are provided that include a flowbody, a butterfly plate, an actuator and an upper chimney and a lower chimney disposed within the flowbody. The flowbody has an inner surface defining a channel. The butterfly plate is disposed in the channel, is rotationally mounted to the flowbody, and has an outer periphery. The actuator has an actuator output shaft that is coupled to the valve shaft via a serrated spline coupling. The upper chimney and the lower chimney are configured to include bearing assemblies that constrain radial loads and thrust loads exerted upon the valve shaft and minimize misalignment of the serrated spline coupling.

    摘要: An air turbine starter for starting an engine includes a housing, and a flow path communicating a flow of gas therethrough; a turbine member; a clutch; and a decoupler device at least partially housed within the output member of the clutch. The decoupler device includes a first shaft portion coupled to and rotating with the output member and a second shaft portion coupled to and rotating with the engine. The first and second shaft portions are axially aligned and configured to engage each another for rotation in a first direction and to separate from each other in a second direction to decouple the output member of the clutch from the engine. The starter further includes a bearing between the inner surface of the output member and the second shaft portion for reducing friction between the second shaft portion and the inner surface of the output member when the first and second shaft portions are decoupled.
