    • A glow plug which includes an annular metal shell, thermally conductive tubular sheath, central electrode; resistance heating element, and electrically insulating, thermally conductive powder includes a glass seal in sealing engagement with the sheath and the electrode to form a sealed cavity within the sheath. The glass seal may include silicate, borate and borosilicate glasses, and may include one or more transition metal oxides, such as oxides of chromium, cobalt, nickel, iron and copper. The glass may also include a filler, including a ceramic oxide, such as one selected from a group consisting of quartz, eucryptites, leucites, cordierites, beta-spodumene, glass-ceramics, low- expansion glass(CTE
    • 一种电热塞,其包括环形金属壳,导热管状护套,中心电极; 电阻加热元件和电绝缘导热粉末包括与护套和电极密封接合的玻璃密封件,以在护套内形成密封腔。 玻璃密封件可以包括硅酸盐,硼酸盐和硼硅酸盐玻璃,并且可以包括一种或多种过渡金属氧化物,例如铬,钴,镍,铁和铜的氧化物。 玻璃还可以包括填料,包括陶瓷氧化物,例如选自石英,锂霞石,白榴石,堇青石,β-锂辉石,玻璃陶瓷,低膨胀玻璃(CTE <5ppm /℃ ),莫来石,锆石,氧化锆和氧化铝。 密封腔可容纳保护惰性气体。 电阻加热元件可以由选自钨,钼或者包含钨,钼,镍,铁,钽,铌,钛,钒,锇和铬的合金的金属形成。

    • A glow plug (10) has a heater probe (20) that can be axially misaligned relative to a central axis (15) of an outer metal shell (12) and of a center electrode (22) and thereafter return automatically to its axially aligned configuration with the central axis. The outer shell has a through bore (14) extending along the central axis. The center electrode is received in the though bore and extends along the central axis. The heater probe is attached in electrical communication with the center electrode in the through bore and extends along the central axis axially outwardly from a distal end (19) of the shell. An annular flex joint (24) provides the sole source of attachment of the outer shell to the heater probe via one end of the flex joint being attached to the outer shell adjacent the distal end and another end of the flex joint being attached to the heater probe.
    • 电热塞(10)具有加热器探头(20),该加热器探头可相对于外金属壳体(12)和中心电极(22)的中心轴线(15)轴向不对准,然后自动返回到其轴向对准 配置中心轴。 外壳具有沿中心轴线延伸的通孔(14)。 中心电极被容纳在通孔中并沿中心轴线延伸。 加热器探针与通孔中的中心电极电连通并且从壳体的远端(19)沿轴向向外延伸。 环形挠性接头(24)通过柔性接头的一端将外壳附接到加热器探针的唯一来源,该柔性接头附接到邻近远端的外壳,柔性接头的另一端附接到加热器 探测。
