Definitions

  • a further advantageous development of the invention provides that the protective tube is electrically isolated from the plug body.
  • This can be achieved, for example, in that the section of the sleeve projecting into the plug body is surrounded by a ceramic ring or a ceramic sleeve, so that an electrically conductive contact between the protective tube and the plug body is prevented.
  • the protective tube is electrically isolated from the plug body, it can be used for measuring and / or monitoring functions, for example as ionization or as a temperature sensor, in particular by the protective tube is designed as a measuring resistor or as a thermocouple.
  • This aspect of the invention may also have independent significance.
  • the present invention therefore also relates to a glow plug with a ceramic glow plug, a thermowell surrounding the glow plug and a plug body from which protrudes the protective tube, wherein the protective tube is electrically isolated from the plug body.
  • FIG. 3 shows a schematic representation of another embodiment of a glow plug. This embodiment differs from that in FIG. 1 illustrated embodiment essentially in that the protective tube 2 narrows at its end remote from the plug body 3 end and engages around a tapered portion of the glow plug 1 around.
  • the protective tube 2 can hold in this way the glow plug 1 in the case of a Glühmannbruchs form fit.
