  • Patent number: 5413479
    Abstract: A discharge-type ignition device for an oil burner capable of permitting ignition of a wick to be carried out at any optimum position of the wick which is fixed. First and second discharge electrodes are arranged in proximity to the wick when it is raised to a combustion position. An ignition switch is kept turned on in the course of upward movement of the wick for ignition, so that spark discharge is generated between the discharge electrodes toward the wick being raised. The wick is raised to an uppermost position beyond the combustion position every time when the ignition operation is carried out, so that ignition may take place at any optimum position of the wick.
