Technical Examples
  1. A pressure-measuring glow plug for a diesel engine with a plug body (3, 4) for insertion into a cylinder of the diesel engine, a heating rod (1) which is arranged in the plug body (3, 4), and a pressure sensor, which is arranged under an initial tension between the heating rod (1) and the plug body (3, 4), in such a way that the pressure sensor (7) is acted upon by the pressure prevailing in the combustion chamber of the cylinder. The heating rod (1) transmits the pressure in the combustion chamber of the cylinder to the pressure sensor (7) and is arranged so as to be displaceable in a sliding manner in the axial direction relative to the plug body (3, 4). A seal in the form of a bellows-shaped component (2) is provided between the heating rod (1) and the plug body (3, 4).
