Beschreibung
Zusammenfassung:	A pressure gauge glow plug for a diesel engine having a plug body, a heating element, and a pressure sensor, which is positioned under pretension between the heating element and the plug body in such a way that the pressure sensor experiences the pressure existing in the combustion chamber of the cylinder in which it is inserted. The heating element is positioned so that it may be slid in an axial direction in the plug body and transmits the pressure in the combustion chamber of the cylinder to the pressure sensor. The pressure sensor is positioned on a heating element support that is permanently bonded to the heating element in a cap that permanently bonded to the plug body. The heating element support and pressure sensor form a unit that has axial play in the interior of the cap.
