  • Patent number: 7954382
    Abstract: 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.

  • Publication number: 20110005308
    Abstract: 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.

  • Publication number: 20100300186
    Abstract: 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.

  • Patent number: 7730771
    Abstract: A device for detecting the combustion-chamber pressure in an internal combustion engine is configured in such a way that the combustion-chamber pressure is able to be detected in a reliable and reproducible manner. To this end, a heating pin exposed to the combustion-chamber pressure is fixed in place in a housing of the glow plug with the aid of a fixation member. A sensor is affixed in the housing of the glow plug via a fixation element set apart from this fixation member. This sensor detects the elastic longitudinal expansion of the housing caused by the combustion-chamber pressure between the end of the fixation member facing the sensor and the fixation point of the fixation element on the housing. This device is preferably utilized in the automotive industry.

  • Publication number: 20100032423
    Abstract: In combustion chamber signal-based engine control in particular, a reliable and at the same time cost-effective option for detecting a combustion chamber pressure in compression-ignition internal combustion engines is required. A sheathed element glow plug is proposed, which has a glow plug module and a pressure measuring module connected to the glow plug module. The glow plug module has a heating element and a glow plug housing. The pressure measuring module has at least one force measuring element, which is integrated into the pressure measuring module. The at least one force measuring element is designed to generate an electrical signal as a function of a force. In the mounted state of the sheathed element glow plug, the at least one force measuring element is connected to the heating element in such a way that a force is transmittable to the at least one force measuring element via the heating element.

  • Patent number: 7472600
    Abstract: The invention relates to a pressure sensor (1), comprising a housing (2), a housing element (3) which may be exposed to a pressure chamber (10), mounted on the housing (2) by means of a metallic membrane (5) and a measuring cell (4) which can indirectly measure a pressure acting on the housing element (3) and transmitted to the measuring cell (4) as a force resulting therefrom. According to the invention, said pressure sensor (1) comprises a housing element (3) embodied as a pin and projects out of the housing (2). The advantage of such an arrangement is only a small drilling to a pressure chamber (10) need be provided, in order to carry out a pressure measurement. The pin (3) need only be so long that the front end thereof, in the assembled state, approximately reaches the wall (11) of the pressure chamber (10).
