    摘要： Disclosed herein is a spark plug having a wire wound inductive suppressor in its center bore for suppressing radio frequency interference. The suppressor utilizes a conductive, rather than a resistive wire as in many prior art suppressors. In addition, the suppressor employs a core of ferromagnetic materials rather than a ceramic or insulative core. This facilitates the attainment of high inductance values with relatively large diameter wire of comparatively few winding turns, with resistance kept at low values. The inductance produced by the suppressor tends to damp out radio frequency oscillations produced by the ignition system of which the spark plug is a part.

    摘要翻译： 本发明公开了一种火花塞，其火花塞的中心孔具有绕线感应抑制器，用于抑制射频干扰。 如许多现有技术的抑制器那样，抑制器使用导电而不是电阻丝。 此外，抑制器采用铁磁材料的芯，而不是陶瓷或绝缘芯。 这有助于实现具有相对较小绕组匝数的较大直径导线的高电感值，电阻保持在低值。 由抑制器产生的电感趋向于消除由火花塞作为其一部分的点火系统产生的射频振荡。

    摘要： An improved low inductance spring for holding a noise suppression resistor either in the bore of a spark plug insulator or at some other suitable point in the ignition system for an internal combustion engine. The spring is formed from an elongated resilient conductor which is preferably flat. The conductor is shaped to have a plurality of reverse bends which simulate pleats in the bellows of an accordion.
