Patent number: 8038933Abstract: A gas sensor is for determining at least one physical quantity of a gas, e.g., an exhaust gas of an internal combustion engine, the gas sensor having a sensor element that is fixed in a housing of the gas sensor by a seal assembly. The seal assembly includes a sealing element, which has a ceramic and/or a metallic material. After the heat treatment, the sealing element has a maximum decrease in volume of 5 percent, or an increase in volume, based on the volume of the sealing element prior to the heat treatment.Type: GrantFiled: July 26, 2007Date of Patent: October 18, 2011Assignee: Robert Bosch GmbHInventors: Helmut Weyl, Claudio De La Prieta, Andreas Hachtel, Thomas Schulte, Thomas Egner, Juergen Wilde, Markus Siebert, Michael Kupzig, Uwe Glanz, Rainer Mueller, Leonore Schwegler, Petra Kuschel, Andreas Pesch

Patent number: 8001827Abstract: A sensor is provided, in particular a gas sensor for determining the concentration of a gas component in a measuring gas, which has a sensor element that projects from a housing by a measuring-gas-side end section exposed to the measuring gas, and a sheath tube having gas passageways, which is placed over the measuring-gas-side end section and affixed on the housing. To prevent condensation of water vapor contained in the measuring gas in the measuring space enclosed by the housing and the sheath tube, and thus the production of water droplets that reach the hot sensor element, sheath tube and/or sensor element are/is thermally decoupled from the housing. The thermal decoupling is produced using, for instance, a flange sleeve made of a material having poor thermal conductivity, which separates the sheath tube from the housing by a flange and, via a sleeve section, is inserted in the space between the housing and the measuring-gas-side end section of the sensor element.Type: GrantFiled: June 23, 2004Date of Patent: August 23, 2011Assignee: Robert Bosch GmbHInventors: Helmut Weyl, Helmut Denz, Matthias Entenmann

Patent number: 7810375Abstract: A sensor, in particular a gas sensor for determining a physical characteristic of a measuring gas, in particular the temperature of the concentration of a gas component, in particular in the exhaust gas of an internal combustion engine, includes a sensor element which protrudes with a gas-side end section from a sensor housing and having a double protecting tube, which encloses the gas-side end section, and has an outer tube and an inner tube. For improved protection of the sensor element against thermal shock, a reduction in the heating power for the sensor element, and sufficiently high dynamics of the sensor, a cup-shaped central protecting tube is placed over the gas-side end section, the central protecting tube being provided with gas passage apertures in the tube casing, the gas passage apertures being positioned offset to the tube bottom with respect to the gas passage apertures present in the inner tube.Type: GrantFiled: May 10, 2005Date of Patent: October 12, 2010Assignee: Robert Bosch GmbHInventors: Helmut Weyl, Stefan Heinzelmann, Bastian Buchholz

Patent number: 7254984Abstract: A sensor for measuring a physical property of a measuring gas, in particular the oxygen concentration or the temperature in the exhaust gas of an internal combustion engine in a motor vehicle, has a housing, a measuring element whose end section protrudes from the housing, a connector plug mounted on the end section, and a housing shell covering the end section and connector plug with a radial clearance, one shell end of the housing shell being attached to the housing and the other shell end being sealed. To prevent electromechanical breakage in the sensor in the event of extreme vibration stresses or accelerations of the vehicle, the free space within the housing shell is completely filled with a non-conductive granulate.Type: GrantFiled: May 14, 2003Date of Patent: August 14, 2007Assignee: Robert Bosch GmbHInventors: Helmut Weyl, Frank Meier, Peter Dettling, Bettina Schneider

Patent number: 7210331Abstract: A detecting element is described, in particular a gas sensor for detecting the concentration of a gas component in a measuring gas, including a sensor element which is exposable to the measuring gas and has a connecting end section which is contacted by connecting cables and is exposed to a reference gas atmosphere. The end section is accommodated in a protective sleeve having a radial opening over which a gas-permeable diaphragm covering the at least one radial opening is provided, the diaphragm, in turn, being engaged by a clamping sleeve having at least one radial opening. To avoid the axial penetration of liquids between the clamping sleeve and the diaphragm, which would cause the detecting element to malfunction, the clamping sleeve is caulked axially above and below the radial openings. Both caulking zones are designed in such a way that the diaphragm is compressed with increasing force from the inner caulking edges facing each other to the outer caulking edges facing away from each other.Type: GrantFiled: June 17, 2004Date of Patent: May 1, 2007Assignee: Robert Bosch GmbHInventors: Helmut Weyl, Bernhard Wild, Rainer Maier, Michael Liebler, Peter Dettling, Lars Berger

Patent number: 7124622Abstract: A sensing element for determining a physical property of a gas mixture, in particular the exhaust gas of internal combustion engines, includes a sensor element, arranged in a housing and connected to at least one electrical cable, as well as a molded piece, which seals the housing and is made of an elastically deformable material, which encloses the at least one cable in a gas-tight manner by radial compression. To ensure the gas-tightness of the cable feed-through also under a higher temperature load, which results in decreased elasticity of the molded piece, a spring element is arranged inside the molded piece, which is able to be tensioned by the radial compression and in the tensioned state generates a force component that acts on the cables in a radial direction.Type: GrantFiled: October 4, 2004Date of Patent: October 24, 2006Assignee: Robert Bosch GmbHInventors: Helmut Weyl, Rainer Maier
