Patent number: 7237453Abstract: A power control device for drive motors in motor vehicles, in particular an accelerator pedal, includes an operating lever which may be operated by an operating force against a return force from a rest position on pivoting about a pivot axis. A damping device for damping the pivot motion of the operating lever is also included. The damping device is a friction device which includes a friction element. The friction element acts upon a component of the operating lever such that in addition to the return force a friction force is also overcome during a pivot movement of the operating lever in a direction away from the rest position.Type: GrantFiled: December 30, 2004Date of Patent: July 3, 2007Assignee: Siemens AGInventors: Peter Kohlen, Christian Reimann, Joachim von Willich

Patent number: 7143996Abstract: A throttle valve connection piece for an internal combustion engine is disclosed, the piece including a housing and a throughflow opening in which the valve is pivotably mounted around a pivot axis. The pivot axis extends in a perpendicular manner with respect to a longitudinal axis the opening. The valve is used to close the throughflow opening. When in a closed position, the valve is inclined at a defined setting angle in relation to the longitudinal axis. The radial peripheral edge of the valve rests against the inner wall of the throughflow opening and the throughflow opening has a cylindrical shape at least in the region where the valve comes to rest. The cylindrical region of rest in relation to the longitudinal axis of the throughflow opening forms a circular cylinder which is cut on both sides at a certain angle, the levels of the cut are inclined at a similar angle in relation to the longitudinal axis.Type: GrantFiled: February 17, 2004Date of Patent: December 5, 2006Assignee: Siemens AGInventors: Peter Kohlen, Rolf Oppermann
