FIELD: mechanical engineering, possible use in devices for spraying fuel in combustion chambers of gas-turbine engines.
SUBSTANCE: sprayer with oxygen replenishment contains body with fuel collector and outlet nozzle, swirling chamber and screw swirler moveable in axial direction having screw channels, connected to porous insert in outlet portion. Screw swirler with screw channels is provided with axial hollow rod and bellows suspension, held on the body. Porous insert is soldered into immoveable screw swirler with screw channels. Channels of moveable and immoveable swirlers are made identical and oriented along common screw guide. Sprayer has additional collector with oxygen supply channel with pass cross-section adjustable by pressure drop in first contour of gas-turbine engine.
EFFECT: stable combustion, expanded mode of stable operation of combustion chamber in off-design modes.
