| 20080302323 | Pencil-Type Glow Plug Having an Integrated Combustion Chamber Pressure Sensor - A pencil-type glow plug for a self-igniting internal combustion engine is described. The pencil-type glow plug includes a plug body in which a combustion chamber pressure sensor is integrated, and a bar-shaped heating element that protrudes out from the plug body at one end, into the combustion chamber of the internal combustion engine. A force-measuring element of the combustion chamber pressure sensor is accommodated behind the heating element, which moves axially under the influence of force. The force-measuring element is sealed against combustion chamber gases by a steel diaphragm made of a stainless precipitation-hardened maraging steel. | 12-11-2008 |
| 20090041081 | COMBINED PRESSURE/TEMPERATURE SENSOR HAVING CENTRIC TEMPERATURE MEASUREMENT - The present invention relates to a combined pressure and temperature sensor ( | 02-12-2009 |
| 20090205861 | Electrical Contact Device - An electrical contact device comprising a first contact assemblage having multiple contact pads disposed in a row which are allocated to different connection types, and having a second contact assemblage having multiple contact pads disposed in a row in accordance with a predetermined sequence, which are allocated to different connection types and having bonding wire connections that electrically connect at least some of the contact pads of the first contact assemblage to contact pads of the second contact assemblage. To reduce the outlay in terms of adaptation to different predetermined connection type allocations, it is proposed that the number and sequence of the contact pads in the first contact assemblage that are allocated to the different connection types be configured so that for at least two differently predetermined sequences of the contact pads in the second contact assemblage that are allocated to the different connection types, each of the contact pads of the second contact assemblage is to be connected in crossover-free fashion, by way of the bonding wire connections, to a contact pad of the first contact assemblage allocated to the same connection type. | 08-20-2009 |

| 20100083741 | COMBUSTION CHAMBER PRESSURE SENSOR - A combustion chamber pressure sensor for an internal combustion engine, having a sensor body able to be inserted into a receiving bore of the internal combustion engine, which sensor body has on the side of the combustion chamber a sealing device for sealing the sensor body in the receiving bore, and which sensor body is provided with affixation means for fixing the combustion chamber pressure sensor in place inside the receiving bore. The sealing device includes at least one separately produced heat-resistant elastic sealing element, which is disposed around an outer jacket of the sensor body. | 04-08-2010 |
| 20100294028 | DEVICE FOR DETECTING A COMBUSTION CHAMBER PRESSURE OF AN INTERNAL COMBUSTION ENGINE - A device for detecting a combustion chamber pressure of an internal combustion engine, in particular a gasoline engine. The device includes a sensor housing, the sensor housing being set up to be at least partially introduced into a combustion chamber of the internal combustion engine. At least one mechanical-electrical transducer element is accommodated inside the sensor housing, which is separated from the sensor housing by at least one sensor holder, in particular a sensor holder which at least partially encloses the mechanical-electrical transducer element. The sensor holder has an at least partially rigid design. | 11-25-2010 |
| 20110123261 | THREADED CONNECTION PIECE - A threaded connection piece, e.g., a connection piece of a sensor, includes a cylindrical base body that is able to be at least partially introduced into an accommodating opening, which is provided, at least over a part of its longitudinal extension, with a threaded section and, at its end face, with a sealing surface. In order to improve the sealing properties of the threaded connection piece when it is screwed into the accommodating opening, the cylindrical base body is developed to be elastic between the threaded section and the sealing surface. | 05-26-2011 |
