Patent number: 5942092Abstract: A sensor device, particularly for determining the oxygen content in exhaust gases of internal combustion engines, having a sensor element that is surrounded gas-tight by a seal and fixed in a housing. The seal (19) is inserted as a pre-sintered, deformable sealing body (19') into the housing (12), between a ceramic molded body on the side of the measured gas and a ceramic molded body on the connection side (18, 20); the pre-sintered sealing body (19') can be deformed under pressure. The ceramic molded parts (18, 20) and the sealing body (19') have respective axially-extending throughgoing holes (32, 42, 52). The sealing body (19') has formed-on structures that narrow the cross section of the throughgoing hole (42) and are deformed by the sensor element (22) when the sensor element (22) is inserted such that the sensor element (22) is stopped, arrested or fixed in the installed position in the throughgoing hole (42) by the formed-on structures.Type: GrantFiled: October 7, 1997Date of Patent: August 24, 1999Assignee: Robert Bosch GmbHInventors: Helmut Weyl, Romuald Fries, Frank Pelz

Patent number: 5795454Abstract: A seal for a sensor element of a gas sensor for determining the oxygen content in gases including exhaust gases of an internal combustion engine, which seal seals the sensor element in a longitudinal bore of a housing, the seal including a sealing stack which is positioned within the longitudinal bore of the housing and around the sensor element in use and which is comprised of two sealing bodies and an additional seal positioned between the two sealing bodies. The two sealing bodies are comprised of a pre-sintered ceramic material. The additional seal is comprised of a pre-pressed powder material and has a porosity which is lower than that of the two sealing bodies. The two sealing bodies and the additional seal are compressed together within the longitudinal bore in use, whereby at least the additional seal is deformed so that the sensor element is sealed in a gap-free manner within the longitudinal bore.Type: GrantFiled: December 4, 1995Date of Patent: August 18, 1998Assignee: Robert Bosch GmbHInventors: Karl-Hermann Friese, Helmut Weyl, Romuald Fries, Hans-Martin Wiedenmann, Anton Hans

Patent number: 5739441Abstract: An arrangement of a sensor element of an electrochemical measuring sensor in a metallic housing is proposed, wherein the sensor element (13) in the form of a tube closed at one end rests with a metallic sealing ring (18) on a seal seat (16) implemented on the housing. The seal seat (16) is designed as a raised circular ring surface having a radius (r), with the sealing ring (18) orienting itself tangentially with respect to the radius (r).Type: GrantFiled: October 17, 1996Date of Patent: April 14, 1998Assignee: Robert Bosch GmbHInventors: Karl-Hermann Friese, Helmut Weyl, Romuald Fries

Patent number: 5711863Abstract: The invention proposes a measuring-probe arrangement for detecting gases flowing in a gas conduit, especially exhaust gases flowing in an exhaust conduit of internal combustion engines. The measuring-probe arrangement has a measuring element (13) which is surrounded in sealing fashion by a housing (11). The section of the measuring element (13a) located at the measured-gas end of the measuring-probe projects from the housing (11) and is surrounded with a clearance by a protective tube (21) which is fixed by one end section on the housing (11) and has one or more openings (22) for the measured gas. The measuring probe (10) is arranged in such a way in the gas conduit (30) that the gas opening (22) is arranged on that side of the protective tube (21) which faces away from the flow (35) of the measured gas.Type: GrantFiled: September 29, 1995Date of Patent: January 27, 1998Assignee: Robert Bosch GmbHInventors: Konrad Henkelmann, Romuald Fries

Patent number: 5698084Abstract: An electrochemical measuring sensor for determining the oxygen content of gases, such as exhaust gases of internal combustion engines, includes a housing having an annular sealing seat defined on an inner surface thereof; a sensor element which is comprised of a solid electrolyte body which is oxygen-ion conducting, which has a form of a tube having a closed end and which has an annular shoulder provided thereon; and a seal ring positioned between the annular sealing seat of the housing and the annular shoulder of the solid electrolyte body, and including a plurality of resilient elements distributed thereon.Type: GrantFiled: February 6, 1996Date of Patent: December 16, 1997Assignee: Robert Bosch GmbHInventors: Helmut Weyl, Romuald Fries, Peter Jansing

Patent number: 5440933Abstract: In a pressure sleeve in particular a vibration pickup, an abutment surface is formed as a circumferential ring at a location radially spaced from a central point. Therefore, the pressure sleeve can be fully pressed against the structure to be monitored by a mounting screw. Therefore a sensor provided with the pressure sleeve can approximately linearily extending and disturbance measuring signals.Type: GrantFiled: March 30, 1994Date of Patent: August 15, 1995Assignee: Robert Bosch GmbHInventors: Hartmut Brammer, Romuald Fries, Karl Dums, Holger Krebs

Patent number: 5398540Abstract: A knock sensor for indirect or direct fixing to an internal combustion engine has a housing (10) with a pressure sleeve (11) on the outer side of which a piezoceramic disk, a seismic mass (16), the contact disks (14), and the insulating disks (13) are arranged. The insulating disks (13) or the piezoelectrical disk (15) are or is made slightly electrically conductive so that the voltage spikes which occur due to the pyroelectrical effect can be easily eliminated. In this way, faulty measuring and interference can be avoided in the electrical circuit connected to the knock sensor.Type: GrantFiled: June 11, 1993Date of Patent: March 21, 1995Assignee: Robert Bosch GmbHInventors: Robert Entenmann, Joerg Bonitz, Stefan Unland, Romuald Fries, Robert Sloboda, Klaus Schenk, Karl Dums

Patent number: 5246562Abstract: A gas measurement sensor (10) which sealingly encloses an axially oriented sensor (27) having an elongated, planar shape in the longitudinal bore (19) of its metal housing (11); while the section (27/1) on the gas measuring side of the sensor (27) has at least one sensor element (38) and possibly heating elements, the end section (27/3) on the connecting side is provided with layered contact surfaces (36), which are in contact with the sensor elements (38)/heating elements via strip conductors (37). A connector plug (43) surrounding the sensor (27) on the connecting side consists of a contact element support (44), an opposite wall (45), contact elements (46) and an annularly-shaped spring element (47); because of its mechanical pre-stressing, the spring element (47) presses the contact elements (46) of the contact element support (44) and of the opposite wall (45) against the contact surfaces (36) of the sensor (27).Type: GrantFiled: June 24, 1992Date of Patent: September 21, 1993Assignee: Robert Bosch GmbHInventors: Helmut Weyl, Romuald Fries

Patent number: 4788885Abstract: A housing having an inner part radially inside of an outer part so as to form a hollow space therebetween. The outer part has two opposite end portions which radially extend inward toward the inner part so as to further define the hollow space. The end portions and the inner part form interengaging projections and grooves. The inner and outer parts are composed of different materials with different heat expansion coefficients. The interengaging projections and grooves are thermally expanded against each other to effect a moisture-tight sealing of the hollow space.Type: GrantFiled: January 12, 1988Date of Patent: December 6, 1988Assignee: Robert Bosch GmbHInventor: Romuald Fries
