  • Patent number: 9874195
    Abstract: A pressure-measuring glow plug device includes a module housing, a glow plug configured to ignite a combustion mixture in a combustion chamber of an internal combustion engine, and a pressure-measuring device. The pressure-measuring device has a pressure sensor configured to detect the pressure in the combustion chamber. The glow plug is connected to the module housing by a flexurally elastic membrane. The force acting on the glow plug in the combustion chamber is transferred to the pressure sensor, which is supported on a supporting element by a preloading force. The supporting element is fastened rigidly to the module housing by a sensor housing. The glow plug device further includes a separate loading sleeve that is connected at one end to the pressure-transferring piece and at the other end to the supporting element. The loading sleeve is configured to apply the preloading force for the pressure sensor.

  • Patent number: 9541291
    Abstract: 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.

  • Patent number: 9500365
    Abstract: 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.

  • Publication number: 20150135811
    Abstract: Described is an elastic diaphragm for a pressure-measuring device for ascertaining a pressure in a combustion chamber of an internal combustion engine, especially a self-ignitable internal combustion engine, the diaphragm being accommodated in a housing of the pressure-measuring device in order to separate a pressure chamber from a cavity and in order to seal the housing from the pressure to be measured. The diaphragm has a pressure-application region. Furthermore, the diaphragm is developed in the shape of a ring and in cross-section has a U-shape that is open toward the cavity; the region of the diaphragm on which the pressure is acting is geometrically made up of two interconnected quarter circles, so that the pressurized region has a structure that is self-supporting with respect to the arising combustion pressure loads.

  • Patent number: 7992443
    Abstract: A sensor design, respectively a micromechanical sensor structure for capacitive relative-pressure measurement, that will allow very small pressure differentials to be reliably recorded at high absolute pressures even in harsh, particle-laden measuring environments. For that purpose, the micromechanical sensor element includes a deflectable diaphragm structure which is provided with at least one deflectable electrode, and a fixed support structure for at least one fixed counter-electrode which is located opposite the deflectable electrode. The diaphragm structure includes two mutually parallel configured diaphragms that are joined rigidly to one another via at least one connecting crosspiece, so that each application of force to one of the two diaphragms is directly transmitted to the respective other diaphragm.
