Abstract: A fluid spray nozzle tip can include a feed hole body that defines at least one feed hole and a spray outlet, the at least one feed hole being in direct fluid communication with the spray outlet without also being in fluid communication with an upstream spin chamber. The at least one feed hole can be a plurality of feed holes, wherein the tip further includes a pintle sealing surface body extending from the feed hole body and configured to allow a pintle to seal against a sealing surface thereof.

Abstract: A nozzle includes an outer gas flow path, an inner gas flow path radially inward from the outer gas flow path, a liquid flow path defined radially between the inner gas flow path and the outer gas flow path, and a core conduit defined radially inward from the inner gas flow path. An injector assembly includes an outer housing, a nozzle within the outer housing, and an outer housing gas flow path defined radially outward from the nozzle between an inner surface of the outer housing and an outer surface of the nozzle. The nozzle includes an outer gas flow path, an inner gas flow path radially inward from the outer gas flow path, a liquid flow path defined radially between the inner gas flow path and the outer gas flow path and a core conduit defined radially inward from the inner gas flow path.

Abstract: A method of injecting fuel in a gas turbine engine includes injecting gaseous fuel from a gaseous fuel circuit of an injector in a first mode, wherein flow of gaseous fuel from the gaseous fuel circuit constricts air flow from an air circuit. The method includes injecting liquid fuel from a liquid fuel circuit in a second mode, idling flow in the gaseous fuel circuit and flowing air through the air circuit for passive purge to prevent liquid fuel from migrating into the gaseous fuel circuit. The method includes injecting a gaseous fuel that lies within a range of different Wobbe Index values, wherein regardless of where the gaseous fuel falls in the range, it does not prevent operation in the first and second modes as described above.

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 translation: 用于调节流体双向流动的阀通过其中包括限定通道的第一流动体，所述通道被构造成沿着从入口到出口限定的下游方向引导流体流动。 入口包括放大部件，其被构造成相对于沿着与下游方向相反的上游方向的流动而向下游方向提供降低的流体流动阻力。

Abstract: A fuel injector for an exhaust heater includes a cover and an air blast nozzle. The cover has a nozzle seat, a fuel inlet, and an air inlet, the nozzle seat arranged along a flow axis. The air blast nozzle is seated in the nozzle seat and has a unibody. The air blast nozzle unibody is in fluid communication with the fuel inlet and the air inlet arranged along the flow axis to port fuel and air into a combustion volume, e.g., to heat a stream of exhaust gas flowing between an engine and a catalytic reactor by combustion with fuel introduced through the fuel inlet and air introduced through the air inlet.

Abstract: A spray nozzle comprising a housing including a primary passage defining a primary axis, a series of secondary passages configured to provide swirl to a fluid passing therethrough circumferentially positioned around the housing, a series of standoffs circumferentially spread around an outer surface of the housing and located downstream along the primary axis of the series of swirling passages, wherein each of the swirling passages corresponds to a respective standoff of the series of standoffs, in order to control the swirl of the fluid.

Abstract: A nozzle for injecting liquid includes a nozzle body defining a flow channel and a swirl ante-chamber in fluid communication with the flow channel. An injection point orifice is defined in the swirl ante-chamber. The flow channel feeds into the swirl ante-chamber to impart a tangential flow component on fluids entering the swirl ante-chamber to generate swirl on a spray issuing from the injection point orifice. A second flow channel can be included in fluid communication with the swirl ante-chamber. The second flow channel feeds into the swirl ante-chamber in cooperation with or in opposition to the first flow channel. The first flow channel, second flow channel, and swirl ante-chamber are configured and adapted to adjust spray angle of a spray issuing from the injection point orifice by varying flow apportionment among the first and second flow channels.
