  • Patent number: 6759631
    Abstract: A ceramic sheathed-element glow plug includes a ceramic glow element made of an electrically conductive layer and an electrically insulating layer, in which the conductive layer is made of supply layers and a heating layer. The higher specific electrical resistance of the heating layer allows the temperature of the heating layer and of the combustion chamber to be determined, and the electrical contact between a connecting element and the glow element is established by a contacting element that is composed of a pellet made of an electrically conductive powder.

  • Publication number: 20030173805
    Abstract: A process for increasing or reducing the internal pressure of at least one hollow body (HK—1, HK—2, HK—3) to a specified set internal pressure. The set internal pressure is adjusted so that several pressure-increasing steps or pressure-reducing steps are conducted successively until the internal pressure deviates from the set internal pressure at most by a specified tolerance. Each of these steps brings about a pressure increase or pressure reduction the amount of which is not larger than a specified upper limit. In this way, impairments of comfort owing to the rise in pressure or the reduction in pressure are especially avoided. The actual internal pressure is only measured at the beginning of the process, the amount is calculated. In one design of the invention, this amount depends upon the volumes of the hollow bodies (HK—1, HK—2, HK—3) and a supply line (VL) as well as (in the case pressure is increased) from the pressure which a pressure generator generates.
