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.

A fuse () is proposed for interrupting a voltage and/or current-carrying conductor () in case of a thermal fault, having a conductor bar () ensuring an electrically conductive connection of the voltage and/or current-carrying conductor during correct operation, said fuse () being characterized in that the conductor bar () melts upon an increase in temperature above the melting point, and the electrically conductive connection of the voltage and/or current-carrying conductor is interrupted due to inherent surface tension. Also proposed is a method for producing the fuse () according to the invention.

A pressure measuring device suitable for disposition in a chamber of an internal combustion engine. The pressure measuring device has a housing, a force transmitting element that is effectively connected to a pressure sensor, and a sensor cage that surrounds the pressure sensor. The sensor cage is connected to the housing by a circumferential weld seam only at one connection segment of the housing. In this way, it is possible to achieve a defined pre-tensioning of a metal diaphragm that is connected on the one hand to the sensor cage and on the other hand to the force transmitting element.

The invention relates to a component for installation in force or pressure sensors, in particular in a glow plug. The component comprises a disc-type or punched-disc type measuring element consisting of a piezoelectric material, punched-disc type or disc-type electrodes that lie on either side of the measuring element. The electrodes have contact points for contacting conductors. The component comprises in addition a respective transmission body or several transmission bodies that are located outside the electrodes, on either side of the latter. The measuring element, electrodes and transmission bodies are held together mechanically by an external, electrically insulating film.

A sheathed-element glow plug is used to be situated in a chamber in an internal combustion engine. The sheathed-element glow plug has a housing, a pin-shaped heating element, which extends partially from the housing and a pressure sensor which is situated in an inner chamber of the housing. A prestressing sleeve is provided, in this context, which applies a prestressing to the pressure sensor.

The invention relates to a pressure sensor (), comprising a housing (), a housing element () which may be exposed to a pressure chamber (), mounted on the housing () by means of a metallic membrane () and a measuring cell () which can indirectly measure a pressure acting on the housing element () and transmitted to the measuring cell () as a force resulting therefrom. According to the invention, said pressure sensor () comprises a housing element () embodied as a pin and projects out of the housing (). The advantage of such an arrangement is only a small drilling to a pressure chamber () need be provided, in order to carry out a pressure measurement. The pin () need only be so long that the front end thereof, in the assembled state, approximately reaches the wall () of the pressure chamber ().
