ELECTRIC-SPARK LIGHTER Russian patent published in 1996 - IPC

FIELD: domestic appliances; lighting of gas stoves. SUBSTANCE: electric-spark lighter has charging rectifier whose output is connected to energy storage capacitor and power input of driven oscillator with closed input in no-load condition controlled by hand-operated switching element. Oscillator output is connected to primary winding of step-up transformer whose secondary winding is connected to electrodes of electric spark gap. Two examples illustrate lighters in which pulse oscillator is assembled in simple circuit incorporating only two component: three-pole switch and additional capacitor. EFFECT: simplified design. 3 cl, 4 dwg
