Patent number: 7032438Abstract: A pressure gauge glow plug for a diesel engine having a plug body, a heating element, and a pressure sensor, which is positioned under pretension between the heating element and the plug body in such a way that the pressure sensor experiences the pressure existing in the combustion chamber of the cylinder in which it is inserted. The heating element is positioned so that it may be slid in an axial direction in the plug body and transmits the pressure in the combustion chamber of the cylinder to the pressure sensor. The pressure sensor is positioned on a heating element support that is permanently bonded to the heating element in a cap that permanently bonded to the plug body. The heating element support and pressure sensor form a unit that has axial play in the interior of the cap.Type: GrantFiled: May 13, 2005Date of Patent: April 25, 2006Assignee: Beru AGInventors: Stefan Heinzelmann, Frank Pechhold, Arno Marto

Patent number: 6070883Abstract: The invention relates to a sealing unit for a fuel pressure sensor for sealing an at least virtually flat sealing joint between the sensor and a component that carries it via a screw connection, wherein a round sealing washer with a central bore is disposed between the threaded bolt-shaped end of the sensor housing with its central sensor bore and the bottom of the threaded bore of the component with its central pressure fluid opening. A pin is formed onto the threaded bolt-shaped end of the sensor housing, which pin centers the sealing washer, fixing it in a positive and/or frictional, non-positive manner, and rises above an end face that serves as a bearing surface for the sealing washer. The pin ends in an end face and has a length that is shorter than the thickness of the sealing washer. A sealing unit is produced that assures a reliable sealing function and permits a simple installation and disassembly of the sealing washer while reclaiming the sealing washer in a sealing position.Type: GrantFiled: June 25, 1997Date of Patent: June 6, 2000Assignee: Robert Bosch GmbHInventor: Heinz-Arno Marto
