Abstract
An engine air valve assembly 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 and a valve housing portion joined via a joint section. The regulating valve housing is a single integral piece.
Claims18
An engine air valve assembly for a gas turbine engine comprising:
- a butterfly valve including a translation shaft;
- a fueldraulic actuator including a piston, the piston being mechanically linked to the translation shaft by an axial to rotational conversion linkage;
- and
- a regulating valve housing containing the butterfly valve and the fueldraulic actuator, the regulating valve housing comprising an actuator housing portion and a valve housing portion joined via a joint section, the regulating valve housing being a single integral piece.
A method for assembling an engine air valve comprising:
- additively manufacturing a regulating valve housing comprising an actuator housing portion and a valve housing portion joined via a joint section as a single integral piece;
- and
- inserting a butterfly valve in the valve housing portion, a fueldraulic actuator piston in the actuator portion, and a translation shaft connecting the butterfly valve to the fueldraulic actuator piston.
