FIELD: machine building.
SUBSTANCE: invention relates to gas turbine engine building, in particular to designs of combustion chambers of gas turbine engines, which serve to drive an electric generator or a supercharger of a gas compressor unit. Combustion chamber of gas turbine engine contains housing, on bosses of which fuel injectors are fixed with flanges, end of each nozzle is installed in the hole of the swirler housing, which is included in the burner, which is fixed in the ring head by means of a threaded nut; a sealing unit is installed between the ends of each nozzle and the swirler housing. Nozzle comprises a housing, a gas distribution sleeve, sealing rings, a splined nut, which is locked by rolling of the nozzle housing, the threaded nut has a smooth entrance, a row of cooling holes is located on the annular head, between the head of the ring nut and the threaded nut there is a lock ring, the sealing unit is fixed in the hole of the swirler housing by welding the support ring to the swirler housing.
EFFECT: invention allows improving reliability, simplifying the nozzle design, assembly and repair.
