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.
