Abstract

PURPOSE:To enable a specified electrical discharging energy to be attained by a method wherein a presser bar spring for use in shielding a discharging of gas is provided with a pillow and the gas is discharged without enabling a nozzle to be moved. CONSTITUTION:When a presser bar spring 5 is pushed through a thin walled part 2a of a nozzle housing 2, a pillow part 6 arranged at the presser bar spring 5 is contacted with a recess 11 of a nozzle 3. When the presser bar spring 5 is further moved, a valve disc 4 fixed to the presser bar spring 5 is moved away from a metallic disk plate 10 around a fulcrum point of the contact point between the pillow part 6 and the nozzle 3 to cause the aeration hole 14 in the disk plate 10 being closed to be released. Due to this fact, fuel gas already reached up to the aeration hole 14 of the disk plate 10 is discharged to a flame port of the nozzle 3. Since the valve opening or closing mechanism has the nozzle 3 fixed thereto, so that the electrical discharging distance between the electrical discharging electrode and the nozzle 3 is kept constant and then an electrical discharging energy always being kept constant can be attained.
