Abstract:
1. A pressure-measuring glow plug for an air-compressing, self-igniting internal combustion engine, comprising: a housing; a force-transmitting element that protrudes at least partly from the housing at a chamber-side opening of the housing; a pressure sensor that is situated in an interior space of the housing, the pressure sensor standing in effective connection with the force-transmitting element; and a diaphragm that seals the interior space of the housing in which the pressure sensor is situated against the chamber-side opening, wherein the diaphragm has a force-transmitting segment that is oriented at least generally in an axial direction of the force-transmitting element, and the pressure sensor stands in effective connection with the force-transmitting element at least via the force-transmitting segment of the diaphragm.
