摘要： A pressure measuring glow plug includes: a housing in which a heating pin for igniting a combustion mixture of an internal combustion engine and a pressure measuring unit for recording a combustion chamber pressure of the internal combustion engine are situated. The heating pin has a glow current contact for an electric heating element. At the end of the heating pin facing away from the combustion chamber, a pressure transmitting element is fastened, which transmits the combustion chamber pressure acting on the heating pin to the pressure measuring unit. The pressure transmitting element is sleeve-shaped and forms an accommodation space for the glow current contact of the heating element.

摘要： A pressure-measuring glow plug has a heating pin for igniting a combustion mixture of an internal combustion engine and a pressure sensor for detecting a combustion chamber pressure of the internal combustion engine. The pressure-measuring glow plug has a contacting unit which includes a carrier for accommodating a signal processing unit and a plug connection having connecting contacts in a plug housing. A glow module housing for accommodating the heating pin and the pressure sensor and an electronic module housing for accommodating the carrier are provided. The electronic module housing is connected at a glow module-sided connecting location to the glow module housing and, at a plug-sided connecting location, to the plug housing.

摘要： A pressure-measuring device for recording a pressure in a combustion chamber of an internal combustion engine, having a force transmission body, situated in a housing, which is exposed to the combustion chamber and which transmits the combustion chamber pressure to a pressure-measuring unit at least indirectly by an axial motion, and having a flexible diaphragm, which is situated between the force transmission body and the housing. The flexible diaphragm is configured to be resilient to implement the axial motion of the force transmission body within the housing. A flexible additional diaphragm is connected ahead of the flexible diaphragm on the combustion chamber side, which seals the flexible diaphragm from the combustion chamber.
