Patent number: 8250909Abstract: 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.Type: GrantFiled: January 12, 2007Date of Patent: August 28, 2012Assignees: Robert Bosch GmbH, Kistler Holding AGInventors: Christoph Kern, Reinhold Hess, Reiko Zach, Michael Kleindl, Peter Wolfer, Steffen Schott, Claudio Cavalloni, Pavlo Saltikov, Michael Mueller, Andrea Bertola

Patent number: 8003917Abstract: A glow plug for a combustion chamber of a self-igniting internal combustion engine has a ceramic heating element designed as a sheathed-element glow plug, which is surrounded by a supporting tube. The ceramic heating element is sealed with respect to the combustion chamber of the internal combustion engine by a seal in the supporting tube. The seal is designed as a sealing element made of an FeNi alloy having an Invar effect.Type: GrantFiled: March 6, 2008Date of Patent: August 23, 2011Assignee: Robert Bosch GmbHInventors: Christoph Kern, Ewgenji Landes, Reiko Zach, Michael Kleindl, Christian Doering, Steffen Schott, Pavlo Saltikov

Patent number: 7994690Abstract: 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.Type: GrantFiled: February 22, 2006Date of Patent: August 9, 2011Assignee: Kistler Holding AGInventors: Peter Wolfer, Claudio Cavalloni, Reinhold Hess, Michael Mueller, Andrea Bertola, Christoph Kern, Steffen Schott, Pavlo Saltikov, Michael Kleindl, Reiko Zach

Patent number: 7954382Abstract: 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.Type: GrantFiled: October 16, 2007Date of Patent: June 7, 2011Assignee: Robert Bosch GmbHInventors: Christoph Kern, Ewgenij Landes, Reiko Zach, Michael Schuettoff, Michael Kleindl, Christian Doering, Steffen Schott, Pavlo Saltikov

Patent number: 7712444Abstract: 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.Type: GrantFiled: November 23, 2006Date of Patent: May 11, 2010Assignee: Robert Bosch GmbHInventors: Christoph Kern, Reinhold Hess, Reiko Zach, Michael Kleindl, Peter Wolfer, Steffen Schott, Claudio Cavalloni, Pavlo Saltikov, Michael Mueller, Andrea Bertola

Publication number: 20090314061Abstract: A pressure-measuring device is used for placing in a chamber of an internal combustion engine. The pressure-measuring device has a housing, a force-transmitting element in operative connection with a pressure sensor, and a centering element. The pressure sensor is placed, together with contact plates, on a centering section of the centering element, thereby making it possible to position the pressure sensor and the contact plates within the housing of the pressure-measuring device. The assembly of the pressure-measuring device is thereby facilitated, and a preassembly is possibly allowed.Type: ApplicationFiled: January 12, 2007Publication date: December 24, 2009Inventors: Christoph Kern, Reiko Zach, Michael Kleindl, Steffen Schott, Pavlo Saltikov
