IGNITOR OF COMBUSTION CHAMBER OF GAS TURBINE ENGINE Russian patent published in 1997 - IPC

FIELD: engine engineering. SUBSTANCE: screen 8 with cut sector 9 that points in the direction of spark plug 5, and two side segments 10 and 11 is mounted inside the housing of the ignitor perpendicular to the axis of sprayer 6. The top angle of sector 9 of screen 8 is defined by a relationship presented in the invention description. Sector 9 of screen 8 points to the spark plug. As a result only the portion of fuel that enters the ignition zone through open sector 9 of screen 8 takes part in mixture formation.
