THERMOCUTTER HEAD Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: thermocutter head includes nozzle, gas generator with combustion chamber and prechamber, fuel supply line for tangential supply of fuel relative to walls of gas generator, oxidizer supply line and igniter; prechamber has three stages. Diameters of stages increase in succession towards combustion chamber. Oxidizer supply line is brought in communication with stages of larger and smaller diameters by means of passages. Fuel supply line is brought in communication with stage of average diameter; igniter is located in stage of smaller diameter, thus making it possible to use different fuels and oxidizers without readjustment of components of device. EFFECT: completeness of combustion; reduction of overall dimensions and mass. 6 cl, 2 dwg
