    摘要： A pressure-measuring device is to be placed in a chamber of an internal combustion engine. The pressure-measuring device has a housing, a force-transmission element projecting out of the housing, and a pressure sensor disposed in an interior chamber of the housing. On the one hand, the pressure sensor is braced on a fixation element. On the other hand, to detect a pressure prevailing inside the chamber, the pressure sensor is operatively connected to the force-transmission element. The pressure sensor has a straight-through recess through which an electrical line is routed. In addition, a positioning element is provided, which has a straight-through recess in a guide region, the electrical line being routed through the straight-through recess, and the positioning element having a reduced thickness in the guide region. This makes it possible to reduce friction of the electrical line in the guide region at the straight-through recess, so that the pressure measurement is improved.

    摘要： A pressure-measuring device is situated in a chamber of an internal combustion engine. The pressure-measuring device has a housing, a force-transmitting element that protrudes partly from the housing at a chamber-side opening of the housing, and a pressure sensor that is situated in an interior space of the housing. The pressure sensor stands in effective connection to the force-transmitting element. In addition, a diaphragm is provided that seals the interior space of the housing, in which the pressure sensor is situated, against the chamber-side opening. The diaphragm, which is preferably fashioned as a metal diaphragm, has a force-transmitting segment that is oriented in an axial direction of the force-transmitting element. Moreover, the pressure sensor stands in effective connection with the force-transmitting element via the force-transmitting segment of the diaphragm. In this way, there takes place at least a partial compensation of thermally caused changes in length of the diaphragm, caused for example by hot combustion gases, and resulting in periodic impairments of the pressure measurement made by the pressure sensor.
