摘要： An engine air valve assembly (100) for a gas turbine engine includes a butterfly valve having a translation shaft and a fueldraulic actuator including a piston. The piston is mechanically linked to the translation shaft by an axial to rotational conversion linkage. A regulating valve housing contains the butterfly valve and the fueldraulic actuator. The regulating valve housing includes an actuator housing portion (120) and a valve housing portion(110) joined via a joint section (130). The regulating valve housing is a single integral piece.

摘要： A valve according to an example of the present disclosure includes a poppet head (18) configured to move with respect to a valve outlet of the valve. A first spring (26) is configured to be compressed with a force generated by fluid flow through the valve, and compression of the first spring (26) allows the poppet head (18) to move towards the valve outlet. A second spring (28) is configured to allow the poppet head (18) to move toward the valve outlet when compressed. A method for controlling fluid flow is also disclosed.

摘要： An example arrangement for cooling a gas turbine engine includes an air turbine starter (110), a starter air valve (104), and an airflow adjustment device (106). The air turbine starter (104) includes a turbine section for rotationally driving a compressor of a gas turbine engine through rotation of a shaft that connects the turbine section to the compressor. The starter air valve (104) is configured to control a flow of pressurized air along a flow path from a source to turbine blades of the turbine section. The starter air valve (104) includes a manual override feature that allows manual opening of the starter air valve (104). The airflow adjustment device (106) is configured to adjust the flow of pressurized air along the flow path when the manual override feature is engaged based on a rotational speed of one of the shaft and an additional shaft that is driven by the compressor.

摘要： A seal (50) for a male outlet (60) having a predefined fluid regulating capability is disclosed. The seal includes a seal body (70) that comprises an aft end (71) including a first surface (710) abuttable with the male outlet (60) and a second surface (711) opposite the first surface (710), and a forward end (72) defining a bore (720) having a fluid regulating capability reduced as compared to the predefined fluid regulating capability of the male outlet (60). The seal further includes a female fitting (80) that comprises an aft end (81) configured for engagement with the male outlet (60), and a forward end (82) disposable about the seal body (70). The seal further includes an intermediate body (90) interposable between the female fitting (80) and the seal body (70) and movable about the seal body (70) with the female fitting (80), the intermediate body (90) comprising a surface (91) configured to abut with the second surface (711) and to force the first surface (710) against the male outlet (60) as the aft end (81) of the female fitting (80) engages with the male outlet (60).
