    • In a glow plug igniter of the type used in internal combustion engines, having a hollow cylindrical casing and a central pin-terminal, a substantially flat-spiral-coiled resistance element, flexible in a direction out of its plane, oriented perpendicularly to the pin-terminal with one end electrically connected to the casing and the other to the pin-terminal, is positioned at a nose end of the casing and spaced from a backing seal of temperature and corrosion-resistant, electrically insulating material hermetically closing the hollow casing. An idle bar of substantial width relative to the resistance element, bridges across the nose end of the casing, spaced from the resistance element. Preferably, the casing is crenellated, with opposed merlons, provided with weld projections, to which the ends of the idle bar are welded.
    • 在内燃机中使用的具有中空圆柱形壳体和中心销端子的类型的电热塞点火器中,基本上平面螺旋线圈的电阻元件在远离其平面的方向上是柔性的,垂直于销 - 末端,其一端电连接到壳体,而另一端电连接到引脚端子,位于壳体的鼻端处,并与温度的背衬密封件隔离并且防腐蚀的电绝缘材料密封地封闭中空壳体。 相对于电阻元件具有相当大的宽度的空闲条,穿过与电阻元件间隔开的壳体的鼻端。 优选地,壳体被锯齿状,具有相对的塞子,设置有焊接突起,怠速条的端部焊接到焊接突起。
