  • Patent number: 11084050
    Abstract: A spray bar injector including a spray bar defining a longitudinal axis and including a fluid inlet and a plurality of spray outlet orifices spaced apart longitudinally in a direction along the longitudinal axis. A check or spray valve is operatively connected to each spray outlet orifice. A master valve is in fluid communication with the fluid inlet, operatively connected to divert flow from the fluid inlet into a first passage and block flow into a second passage in a first position to open the check valves and issue a spray from the spray outlet orifices, and to divert flow from the fluid inlet into the second passage and block flow into the first passage in a second position to close the check valves and block issue of spray from the spray outlet orifices.

  • Patent number: 10094352
    Abstract: A nozzle for injecting liquid includes a nozzle body defining a plurality of injection point orifices and an annular prefilmer positioned downstream of the injection point orifices for prefilming impingement of spray from the injection point orifices on the prefilmer. A swirl antechamber can be defined upstream of the injection point orifices for supplying a swirling liquid flow to the injection point orifices for impingement of a swirling flow on the prefilmer.

  • Publication number: 20170368562
    Abstract: A seeder includes a housing defining a cavity, a housing gas inlet, and a seeder outlet. A sprayer is disposed within the cavity and includes a sprayer gas inlet configured to receive a gas, wherein the sprayer gas inlet is in fluid communication with the housing gas inlet. The sprayer also includes a sprayer liquid intake configured to be in fluid communication with the cavity to intake a liquid media from the cavity and a sprayer nozzle configured to be in fluid communication with the cavity above a liquid level. The sprayer is configured to combine the liquid media with the gas to spray a gas-liquid mixture through the sprayer nozzle and on to an interior spray surface of the housing.

  • Publication number: 20170108222
    Abstract: A method of issuing a spray cone from a nozzle includes modulating flow to two separate first and second fluid circuits, each connected to a common injection point orifice to vary spray angle on a substantially hollow spray cone over time to create a full spray cone. Modulating can include controlling first and second flow modulators, connected to the first and second fluid circuits, respectively, to coordinate oscillating flow rate modulation of both of the first and second fluid circuits. Controlling can include controlling the oscillating flow rate modulation for the first flow modulator to be out of phase with, to be in antiphase with, to be vertically shifted in magnitude relative to, and/or to have an amplitude that is equal to that of the second flow modulator.

  • Publication number: 20160377293
    Abstract: In accordance with at least one aspect of this disclosure, a fuel injector system can include an air mixer defining an outer air circuit, at least one intermediate air circuit, and an inner air circuit. The fuel injector system can also include a fuel manifold defining a fuel circuit, at least a portion of which is operatively disposed within the air mixer such that the fuel circuit and the intermediate air circuit are in fluid communication with each other for atomization of fuel. At least one of the air mixer or the fuel manifold can be additively manufactured.

  • Patent number: 8851401
    Abstract: An injector for injecting a flat fan of liquid includes an injector body defining a pair of air channels, with each air channel fluidly connected to a respective air inlet. The air channels join one another at a common throat defined in the injector body and are separated by a land defined in the injector body extending from the air inlets to a point proximate the throat. The air channels and a liquid inlet are in proximity to draw liquid out of the liquid inlet into the throat with air flowing through the air channels. A diverging diffuser is provided in fluid communication with the throat. The diffuser includes an impingement surface defined in the injector body opposed to the liquid inlet. The liquid inlet is configured to inject liquid against the impingement surface to form a fan of liquid diverging outward through the diffuser.

  • Publication number: 20120292408
    Abstract: A multipoint injector ring includes a distributor ring defining a central axis and having a fluid inlet and a plurality of swirlers in fluid communication with the fluid inlet for imparting swirl on fluid from the fluid inlet. The swirlers are defined in a downstream surface of the distributor ring. An orifice ring is mounted to the distributor ring. The orifice ring defines a plurality of fluid outlets circumferentially spaced apart with respect to the central axis. Each fluid outlet is aligned downstream of a respective swirler for injecting swirling fluid from the swirlers in a downstream direction.

  • Publication number: 20120234013
    Abstract: Combustion systems and the related methods operate to supply a stream of combustion products to a turbine in a gas turbine engine by forming an outer recirculation zone of recirculating combustion products within a combustor and by forming an inner recirculation zone inboard of the outer recirculation zone. The inner and outer recirculation zones are formed by imparting swirl to compressor discharge air passing through an outer air swirler and an inner air swirler radially inboard of the outer air swirler. Fuel is injected from an outer fuel injector into the outer recirculation zone, and fuel is also injected from an inner fuel injector into the inner recirculation zone.
