    Abstract: In one exemplary embodiment of the present disclosure a fluid coupling assembly defining an axial direction, a radial direction, and a circumferential direction is provided. The fluid coupling assembly includes a male coupling including a first MC attachment interface, a second MC attachment interface, and an outer surface extending along the circumferential direction; a ferrule coupling including an FC attachment interface pressed against the first MC attachment interface, a lip extending along the radial direction, and an outer surface extending along the circumferential direction to define a circular shape; and a nut coupling including an NC attachment interface rotatably engaged with the second MC attachment interface, a flange extending along the radial direction and pressed against the lip of the ferrule coupling, and an inner surface extending along the circumferential direction to define a circular shape; wherein the outer surface of the male coupling, the outer surface of the ferrule, or the inner surface of the nut coupling includes a plurality of non-resilient protrusions spaced along the circumferential direction for contacting an opposing

    Abstract: A check valve assembly for a supply pipe. The check valve assembly includes a hinge pin, a first flapper, and a second flapper. The first flapper is pivotally coupled to the second flapper with the hinge pin. The check valve assembly also includes a stopper located between the first flapper and the second flapper. The stopper is configured to limit movement of the first flapper and the second flapper. The check valve assembly further includes a plate assembly located downstream of the stopper. The plate assembly is configured to break vortices formed in a fluid flow across the first flapper and the second flapper.

    IPC: F01D11/00

    Abstract: A gas turbine engine including a wall assembly, a seal assembly, and a member extended through the wall assembly is provided. The wall assembly defines an opening through which the member is extended, and the wall assembly defines a first side and a second side opposite of the first side along a direction of extension of the member through the wall assembly. The seal assembly includes a retaining portion extended at least partially co-directional to the member. The retaining portion is configured to couple around the member and extend through the opening. The seal assembly further includes a locking portion configured to sealingly attach to the wall assembly and the retaining portion at an interface between the locking portion and the retaining portion.
