FUEL INJECTOR FOR TURBOMACHINE Russian patent published in 2019 - IPC F02C7/22 F23R3/34 

FIELD: engines and pumps.

SUBSTANCE: invention relates to a fuel injector for an annular combustion chamber of a turbine engine, such as a turbojet or a turboprop. Fuel injector (10) contains downstream head (16), which has central outlet (22) and annular peripheral outlet (24) surrounding it, and also contains injector arm (12), which is located upstream in front of head (16) and at the same time has coaxial central channel (18) and coaxial annular channel (20). Moreover, central channel (18) is in fluid communication with peripheral outlet (24), and annular channel (20) is in fluid communication with central outlet (22). Also presented are an annular body for a fuel injector, a combustion chamber for a turbine engine that contains at least one fuel injector, and a turbine engine with such a chamber.

EFFECT: invention makes it possible to reduce the danger of fuel sintering due to the fact that the central channel of the injector arm is protected by an annular channel, which prevents sintering of the fuel inside this channel.
