Publication number: 20060174499Abstract: A device for determining an absolute angle of rotation of a rotation axis (12) includes a first measurement arrangement for measuring an angle of rotation in a limited first measurement range and a second measurement arrangement for determining an absolute angle range. The second measurement arrangement comprises a deflection element (20) and a rotation element. The deflection element undergoes a deflection dependent on the rotation of the rotation axis (12). The deflection, in turn, is converted into a rotation of the rotation element (22).Type: ApplicationFiled: January 20, 2006Publication date: August 10, 2006Inventors: Norbert Staudt, Volker Stegmann, Guido Hirzmann, Klaus Weigand

Publication number: 20030015022Abstract: In a method and a device for leak testing of a vessel, e.g., a tank venting system of a motor vehicle, a leak-tightness measurement is performed by introducing a positive pressure or partial vacuum and detecting the variation over time of a positive pressure or partial vacuum in the vessel, and a reference measurement is performed using a reference leak. A conclusion is drawn as to the presence of a leak in the vessel by comparing the results of the leak-tightness measurement and the reference measurement. To avoid faulty diagnoses, the positive pressure or partial vacuum during the leak-tightness measurement and the reference measurement is detected by using a single pressure measuring device.Type: ApplicationFiled: June 24, 2002Publication date: January 23, 2003Inventors: Volker Stegmann, Thorsten Fritz, Martin Streib, Peter Wiltsch, Armin Hassdenteufel

Patent number: 6446615Abstract: A tank-venting system includes an active charcoal filter (20), which is connected to a tank (10). An intake manifold (40) of an internal combustion engine is connected to a tank-venting valve (30). The active charcoal filter (20) stores fuel vaporized in the tank (10). When the tank-venting valve (30) is driven open by the control unit (60), air from the ambient is drawn by suction through the active charcoal filter (20) and the fuel stored therein is released to the inducted air. A pump (50) is provided for checking the tightness of the tank-venting system and is connected to the control unit (60). A switchover valve (70) is connected downstream of the pump (50). A reference leak (81) is arranged in parallel to the switchover valve (70). A throughflow sensor (90) and a temperature sensor (91) are connected forward of the pump (50) which detect the scavenging air quantity, which is used to scavenge the active charcoal filter (20), as well as the intake air temperature.Type: GrantFiled: April 20, 2001Date of Patent: September 10, 2002Assignee: Robert Bosch GmbHInventors: Volker Stegmann, Ralf Klein, Peter Wiltsch
