REGULATOR OF TURNING THE SWIRLER BLADES OF THE FRONT DEVICE Russian patent published in 1995 - IPC

FIELD: gas turbine motors. SUBSTANCE: fuel pressure increases during the changeable modes of operation in fuel flue 12 of sprayer 1. Piston 9 travels compressing spring 11. Piston 15 travels at the same time compressing the corresponding spring in chamber 10. The travel of pistons 9, 15 takes place unless the fuel pressure is equilibrated by the intensity of the spring pressure. Through radial levers 4 and ring 2 intermediate links 16 and dogs 13 of blades 14 of the swirler are synchronously rotated increasing the drive tunnels of the swirler. When the fuel pressure in chamber 10 is levelled off piston 15 will return to the initial position under the action of springs and will displace blades 14 of the swirler through radial levers 4, ring 2, intermediate links 16 and dogs 13. EFFECT: facilitated manufacture. 3 dwg
