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).
