摘要： An example method of accessing a valve assembly of a turbomachine includes accessing a check valve of the valve assembly from a first position that is radially outside a flow path through the turbomachine. The method accessing a shut off valve of the valve assembly from a second position that is radially outside the flow path. The check valve and the shut off valve are configured to influence communication of lubricant along a lubricant communication path that extends between a location radially outboard the flow path and a location radially inboard the flow path. The first position is the same as the second position in some examples.

摘要： A gas turbine engine includes a bearing and a bearing support having a first wall extending between first and second ends and operatively supported by the bearing at a first end. An engine case is secured to the second end radially outward of the first end. A second wall integral with and extending transversely from the first wall provides a flexible support. The second wall has a flange, and a gear train component is secured to the flange. A gas turbine engine includes a support structure which supports the main rotatable structure via bearings and gear train components. The support provides both the necessary structural support for the rotor structure as well as desired flexibility for a fan drive gear system.

摘要： A axial face seal assembly includes first and second structures rotatable relative to one another about an axis. A carrier supports a seal that engages the second structure. The carrier is configured to move along the axis. First and second springs operatively are arranged between the first structure and the carrier. The first and second springs are configured to bias the carrier relative to the second structure respectively in first and second directions along the axis for providing a desired closing force on the second structure. A method of sealing a rotating structure includes biasing a seal toward a rotating sealing surface with a first spring to provide a desired axial closing force. The axial position of the seal relative to the rotating sealing surface is changed to an undesired axial closing force. The seal is biased with a second spring to achieve the desired axial closing force.
