FIELD: manufacture of gas-turbine engines. SUBSTANCE: body of fuel-injection nozzle for gas-turbine engine is made of part of hard material and includes inlet and outlet face parts. Groove means rendered leak-tight over its length with the use of at least one closing means with formation of fuel supply conduit from inlet face part to outlet face part is located on body between inlet and outlet parts. Inlet face part is joined to fuel injector with the help of reducer of fuel line for supply of fuel through body of fuel-injection nozzle. In process of manufacture of body of fuel-injection nozzle first opposite faces of part of hard material are drilled out. Then at least one groove means is built over length of above-mentioned part between inlet and outlet parts. Groove means are sealed with the aid of at least one closing means and form one fuel supply conduit from inlet face part to outlet face part as minimum. EFFECT: updated and more efficient body of fuel-injection nozzle intended to supply fuel from fuel injector to combustion chamber. 24 cl, 8 dwg
