Abstract: An atomizer includes an atomizer body with a plurality of air passages defined therethrough from an upstream end of the atomizer body to a downstream end thereof. The air passages together define an air circuit through the atomizer body. A fuel circuit is defined in the atomizer body extending from a fuel inlet to a respective fuel outlet opening into each air passage. The air passages can be arranged circumferentially about a central axis defined by the atomizer body. The fuel circuit can include a manifold extending circumferentially about the atomizer body in fluid communication with a fuel opening in each respective air passage.

Abstract: A nozzle includes a nozzle body defining a liquid circuit extending from a liquid inlet to a liquid outlet. The liquid circuit includes a plurality of spiral liquid passages spiraling radially inward relative to a spray axis. The spiral liquid passages all lie in a plane normal to the spray axis. A manifold assembly includes a plurality of such nozzles. A manifold ring is in fluid communication with the liquid inlet of each of the nozzles to deliver liquid to the nozzles. The nozzles are circumferentially spaced apart around the manifold ring.

Abstract: A valve for regulating fluid flowing bidirectionally therethrough includes a first flow body defining a passage configured to direct fluid flow in a downstream direction defined from the inlet to the outlet. The inlet includes an enlargement configured to provide decreased resistance to fluid flow in the downstream direction relative to flow in an upstream direction opposite the downstream direction.

Abstract: A nozzle tip includes a nozzle tip body defining an upstream surface and an opposed downstream surface. An outlet orifice is defined through the nozzle tip body for fluid communication from a space upstream of the upstream surface to a space downstream of the downstream surface. The outlet orifice includes a cylindrical outlet portion defining an outlet axis, and a tapered inlet portion upstream of the outlet portion. The tapered inlet portion converges down towards the outlet axis in a direction from the upstream surface toward the downstream surface.

Abstract: A swirler includes a swirler body defining a longitudinal axis. A stack of swirler plates is assembled to the swirler body stacked in a direction along the longitudinal axis. Each of the swirl plates defines a vane portion. The swirler plates are mounted rotated circumferentially about the longitudinal axis relative to neighboring ones of the swirler plates so the vane portions form a swirler vane.

Abstract: A strainer body strainer body has a conical or bullet-like shape and includes a tip portion, a midsection, and a base portion. The midsection connects the tip portion to the base portion such that the tip portion, midsection, and base portion are aligned with one another along a straining axis defined by the strainer body. The strainer body includes a plurality of layers fused to one another and angled relative to the straining axis. The plurality of layers define flow passages that extend through the strainer body to impound particulate entrained in fluid traversing the strainer body through the flow passages of the strainer body.

Abstract: A strainer has a strainer body with a width and a height. The height of the strainer body is smaller than the width of the strainer body. The strainer body has a serpentine cross-sectional profile to provide rigidity and straining area. A fuel injector includes a strainer as described and a nozzle body with a fuel circuit defined therein. The strainer is integrally coupled to the nozzle body and is in fluid communication with the fuel circuit to remove entrained particulate from fuel traversing the strainer prior to the fuel reaching the fuel circuit.

Abstract: A fuel injector for a gas turbine engine includes a nozzle tip assembly having a substantially monolithically formed nozzle body. The nozzle body has an annular outlet chamber for issuing a spray from the nozzle tip. A feed channel is in fluid communication with the outlet chamber through a feed passage. A heat shield void substantially surrounds the feed channel(s).
