GTE COMBUSTION CHAMBER INJECTOR MODULE Russian patent published in 2012 - IPC F23D11/10 F23R3/38 

FIELD: engines and pumps.

SUBSTANCE: proposed module comprises body with fuel feed channel with bore, sleeve with central air channel and outer annular groove, inner air swirler and fuel injection assembly. Said air channel is constricted by nozzle with face edge on sleeve outlet. Said sleeve is arranged in body bore. Inner air swirler is arranged along the axis in sleeve air channel. Inner air swirler is arranged at the sleeve air channel beginning and formed by tangential grooves. Annular space is formed between body bore and sleeve outer surface to communicate with fuel feed channel at inlet and, at outlet, with fuel injection assembly. Fuel injection module is made up of dispensing orifices in sleeve and fuel nozzles with face edge on body bore outlet. Additionally, injector module comprises extra external air swirler arranged said body coaxially with central air bore. Central air bore face inlet is plugged. Body is thread-jointed with sleeve while in injection assembly zone they fit along tapered surfaces. Said dispensing orifices are made on sleeve tapered surface in the form of spiral grooves. Air nozzle face edge is located under fuel nozzle face edge.

EFFECT: higher quality of fuel spray and air-fuel mix homogenisation.
