摘要： A self-pumping fuel injector includes a pump and a motor for, in-part, delivering fuel to a combustor at higher fuel pressures during start-up and ramping-up conditions. Each pump may include a stationary flow interuptor that intermittently and variably supplies fuel to a rotating spindle that, in-turn, expels the fuel into a nozzle of the injector for improve fuel spray distributions.

摘要： A fuel injector for a gas turbine engine includes a feed arm defining a conduit extending between an inlet end and an outlet end and a plunger. The plunger is disposed within the conduit and is movable between a plunger first position and a plunger second position. A flow area defined between the plunger and the feed arm is smaller in the plunger first position than in the plunger second position to bias fuel flow through the fuel injector. Fuel systems, gas turbine engines, and methods of controlling fuel flow in gas turbine engine fuel systems are also described.

摘要： The subject matter of this specification can be embodied in, among other things, a fluid flow trim apparatus includes an outer housing defining a cavity having an interior surface and an end wall having an orifice therethrough, a valve body comprising a first valve portion disposed at least partly within the cavity, the first valve portion and the interior surface defining a first fluid flow path, a second valve portion in contact with the interior surface and defining a second fluid flow path. A third valve portion is disposed at least partly within the cavity between the first and second valve portions. The second fluid flow path fluidically connects the third valve portion to a trim cavity. A filter media extends from the first valve portion to the second valve portion and divides a third fluid flow path fluidically connecting the first and seconds fluid flow paths.

摘要： A fuel injector for a turbine engine, the injector including a body including a primary fuel circuit and a secondary fuel circuit fed by a metering valve. A leakage channel extends from a zone in fluid flow connection with the primary circuit to a zone in fluid flow connection with the secondary circuit. The leakage channel is configured to be open in a closed position of the metering valve and to be closed by the metering valve moving.

摘要： The present invention relates generally to devices designed for the combustion of liquid fuels and specifically to an improved apparatus for burning high-viscosity and waste oil. The subject invention utilizes a piston mechanism to transport fuel from its source to the subject burner. The piston mechanism, in conjunction with a pressure-sensitive valve device, also pressurizes the fuel to a predetermined level before releasing said fuel through a nozzle for pressurized dispersion atomization. The piston speed and stroke length can be adjusted in order to regulate fuel flow. After emission from the nozzle, the atomized fuel encounters a single-spark ignition device to induce flame. The atomized fuel and flame produced is enveloped by a unique retention head designed to promote complete fuel combustion and protect the burner chamber from over-heating.
