COMBUSTION CHAMBER OF GAS-TURBINE ENGINE Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: fuel injectors are secured by flanges on bosses of combustion chamber body of gas-turbine engine. Ends of fuel injectors are installed in holes of vortex-generator bodies secured in burners of flame tube. Floating sealing rings are positioned between ends of fuel injectors and vortex-generator bodies. In addition, stack of disc springs, pressure and supporting rings are positioned between ends of fuel injectors and bodies of vortex generators. Floating sealing ring is of L shape, with disc and cylindrical sections. With its cylindrical section sealing ring is set on ends of fuel injectors. Disc section is arranged between pressure and supporting rings and is clamped between them by stack of disc springs. Stack of disc springs, floating pressure and supporting rings form sealing assembly which is secured in vortex-generator body, for example, by expanding of its bead. EFFECT: enhanced reliability. 2 dwg
