Patent number: 7159844Abstract: A valve having a housing with a valve seat for a two-piece flap which is rotatably mounted on a drive shaft. An annular piston seal and an adjacent cover disk are disposed between the first part and the second part of the two-piece flap so as to revolve there-around. The diameter of the cover disk is smaller than the diameter of the annular piston seal which is embodied as a metal ring that is provided with a gap. The invention also relates to the use of said valve as a gas recirculation valve.Type: GrantFiled: December 16, 2003Date of Patent: January 9, 2007Assignee: Siemens AGInventors: Gerd Bornmann, Peter Kohlen, Michael Rennen

Publication number: 20060060809Abstract: Disclosed is a valve comprising a housing (5) with a valve seat (4) for a two-piece flap (2) which is rotatably mounted on a drive shaft (1). An annular piston seal (3) and an adjacent cover disk (6) are disposed between the first part (2a) and the second part (2b) of the two-piece flap (2) so as to revolve therearound. The diameter of the cover disk (6) is smaller than the diameter of the annular piston seal (3) which is embodied as a metal ring that is provided with a gap (3?). The invention also relates to the use of said valve as a gas recirculation valve.Type: ApplicationFiled: December 16, 2003Publication date: March 23, 2006Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Gerd Bornmann, Peter Kohlen, Michael Rennen

Patent number: 7007926Abstract: The invention relates to a valve comprised of a housing with a valve seat for a flap that is rotatably mounted on a drive shaft. The exterior of the flap is provided with a first piston sealing ring and a second piston sealing ring that are placed inside an encircling groove of the flap. Each sealing ring is provided in the form of a metal ring. The first ring has a first gap and the second ring has a second gap that are not aligned with one another. The invention also relates to the use of said valve.Type: GrantFiled: December 20, 2004Date of Patent: March 7, 2006Assignee: Siemens AGInventors: Peter Kohlen, Michael Rennen

Patent number: 6990873Abstract: The invention relates to an electromotive drive comprising an electric motor, having a driving pinion which meshes with a toothed wheel to form a first gear speed. A worm is connected to an output shaft of the toothed wheel in a fixed manner, enabling a worm wheel to be driven. The worm and the worm wheel form a second gear speed, and the shaft of the worm wheel forms the output shaft of the electromotive drive. The output shaft of the electromotive drive can be rotatably driven between a starting position and an end position. When the electric motor is not fed by a current, the output shaft of the toothed wheel can be rotatably driven by a pull-back spring in the rotational direction towards the starting position. The second gear speed is a non-self-locking gear speed.Type: GrantFiled: December 19, 2003Date of Patent: January 31, 2006Assignee: Siemens AktiengesellschaftInventors: Michael Rennen, Thomas Mann
