Patent number: 7337657Abstract: A pressure glow plug for a diesel engine has a glow plug body 2 for being inserted into a cylinder of the diesel engine, a heating rod 1 that is arranged in the glow plug body 2 and a pressure sensor 9 that is arranged between the heating rod 1 and the glow plug body 2 in such a way that the pressure in the combustion chamber of the cylinder that is transmitted by the heating rod 1 influences the pressure sensor 9. The heating rod 1 is arranged in the glow plug body 2 such that it can be displaced in an axially sliding fashion, namely by a corresponding sliding element, for example, a membrane 7 or seals 3.Type: GrantFiled: September 20, 2004Date of Patent: March 4, 2008Assignees: Beru AG, Texas Instruments Holland B.V.Inventors: Michael Haussner, Ulf Wyrwich, Hans Houben, Frank Pechhold, Heinz-Georg Schmitz, Dirk Von Hacht, Marc Gerard Johan Borgers, Albert Ferdinand Zwijze, Paulus Thomas Johannes Gennissen, Ronald De Groot, Arie-Jan Koelling

Patent number: 7228730Abstract: A pressure-measuring glow plug for a diesel engine with a plug body (3, 4) for insertion into a cylinder of the diesel engine, a heating rod (1) which is arranged in the plug body (3, 4), and a pressure sensor, which is arranged under an initial tension between the heating rod (1) and the plug body (3, 4), in such a way that the pressure sensor (7) is acted upon by the pressure prevailing in the combustion chamber of the cylinder. The heating rod (1) transmits the pressure in the combustion chamber of the cylinder to the pressure sensor (7) and is arranged so as to be displaceable in a sliding manner in the axial direction relative to the plug body (3, 4). A seal in the form of a bellows-shaped component (2) is provided between the heating rod (1) and the plug body (3, 4).Type: GrantFiled: September 13, 2005Date of Patent: June 12, 2007Assignees: Beru AG, Texas Instruments Holland B.V.Inventors: Michael Haussner, Hans Houben, Frank Pechhold, Friedrich Mayr, Ulf Wyrwich

Patent number: 7193183Abstract: A glow plug connector for a glow plug with built-in sensor, especially built-in pressure sensor, comprising a casing made of an electrically insulating material, which can be placed onto the glow plug. Provided centrally in the casing is a high-current connection which is connected to the high-current contact of the heating devices of the glow plug when the connector is placed thereon. Sensor contacts are provided on the casing insulated with respect to the high-current connection for contacting the sensor connections of the built-in sensor when the connector is placed thereon. For sealing an O-ring is provided on the outside of the casing whereas a locking mechanism serves to deliver the withdrawal force which must be overcome so that a coupling placed thereon can be removed from the glow plug connector. The connector is part of a system with a glow plug connector and glow plug.Type: GrantFiled: January 21, 2005Date of Patent: March 20, 2007Assignees: Beru AG, Hirschmann Automotive GmbHInventors: Michael Haussner, Gerald List, Frank Pechhold, Hans Houben, Juergen Haefele, Werner Jaeger

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
