Patent number: 7497207Abstract: A vehicle fuel system having a fuel tank with an opening with a closure disposed adjacent a vehicle component with a service access opening and closure adjacent the tank closure, and an electronic controller carried by the vehicle component closure. At least one electrical device in the tank is connected by an electric wire to the controller. Preferably, a thermal protector is carried by the closure and arranged as a metal heat sink for the controller and dissipates heat to the atmosphere.Type: GrantFiled: January 12, 2006Date of Patent: March 3, 2009Assignee: TI Automotive (Neuss) GmbHInventors: Bernd-Juergen Lahn, Peter Schreuder, Matthias Henschel, Rainer Strauss, Dirk Neulen, Andreas Winkler

Patent number: 7347191Abstract: A fuel system with a fuel tank having at least one opening into an interior of the fuel tank, and an electrically operated vent valve having an inlet communicated with the interior of the fuel tank and an outlet for venting fuel vapor from the fuel tank. The vent valve is movable in response to an electric signal between an open position allowing fuel vapor through the outlet and a closed position to restrict fluid flow through the outlet. A controller is operably communicated with the vent valve to control application of an electric signal to the vent valve and thereby control at least in part the movement of the vent valve between its open and closed positions. In one embodiment the controller is responsive to a fill level in the fuel tank to control the position of the vent valve and thereby the fill level attained within the fuel tank.Type: GrantFiled: June 17, 2005Date of Patent: March 25, 2008Assignee: TI Group Automotive Systems, L.L.C.Inventors: Jeffrey M. Atwood, David A. Brady, John R. Forgue, Matthias Henschel, Mark R. Johansen, Michael Kloess, Peter P. Kuperus, Martin Stickel

Patent number: 7315165Abstract: A sensor element (30) measures a Hall voltage generated by a movable magnet (16). For this purpose, the sensor element (30) comprises a ceramic base element (40) which has connected therewith a detector element (46). The detector element (46) is protected with the aid of a cover element (42) against an aggressive environment produced by fuel or fuel vapors in a fuel tank (34) of a motor vehicle. The detector element (46) has connected therewith electric conductors (60) which are routed through the cover element (42) and/or the base element (40) for connecting the detector element (46) with a voltage source and/or an evaluation unit. The cover element (42) and possibly the base element (40) reliably encapsulate the detector element (46) against the aggressive environment such that by simple constructive measures the service life of the sensor element (30) is increased.Type: GrantFiled: November 18, 2004Date of Patent: January 1, 2008Assignee: TI Automotive (Neuss) GmbHInventors: Alfred Kleinen, Peter Schreuder, Matthias Henschel, Bernd Juergen Lahn

Patent number: 7299675Abstract: A method of calibrating a level sensor installed in an empty tank. In the tank, the level sensor includes a float that is allowed to rest against a first stop, such as the tank bottom or tank top. This position of the float is stored as a first level, such as a minimum level, in memory of sensor electronics of the level sensor. The float is thereafter moved, such as under the force of gravity by inverting the tank, against a second stop such as the tank top or the tank bottom. This position of the float is stored as a second level, such as a maximum level.Type: GrantFiled: December 20, 2005Date of Patent: November 27, 2007Assignee: TI Automotive (Neuss) GmbHInventors: Matthias Henschel, Peter Schreuder

Patent number: 7002276Abstract: An armature of the prior art has a lamination packet which leads to a high loss of magnetic flux in the lamination, since it completely encloses the magnets that are disposed in the lamination. An armature (1) of the invention comprises at least one lamination (1) that only partly encloses the magnets (24). Losses in the magnetic flux are thus reduced.Type: GrantFiled: November 12, 2001Date of Patent: February 21, 2006Assignee: Robert Bosch GmbHInventors: Susanne Evans, Juergen Herp, Matthias Henschel, Harald Bux

Publication number: 20050284448Abstract: A fuel pump system includes a fuel pump having a direct current motor for driving a pumping element to deliver fuel to an engine at a variable rate. A pulse width modulated controller is electrically communicated with the motor for varying the speed thereof, thereby enabling the fuel pump to deliver the fuel to the engine at the variable rate. The controller includes a first switch in series with the motor and a second switch in parallel across the motor. In a motor-off cycle, control electronics connected to the switches deactivate the first switch and activate the second switch to commutate the motor. In a motor-on cycle, the control electronics deactivate the second switch and activate the first switch to power the motor.Type: ApplicationFiled: June 15, 2005Publication date: December 29, 2005Inventors: John Forgue, Matthias Henschel, Michael Riddell, Peter Schreuder

Patent number: 6829815Abstract: Sheet-metal blanks for rotors or stators of electrical machines are cut from rolled sheet-metal strips with a magnetic preferential direction and layered to form a laminated rotor core or laminated stator core. To compensate largely for a magnetic anisotropy of the laminated rotor core or laminated stator core, the sheet-metal blanks, when they are not centrosymmetrical, are cut out together congruently in a single cutting operation, from rolled sheet-metal strips stacked one above the other and rotated relative to one another by an angle.Type: GrantFiled: August 7, 2001Date of Patent: December 14, 2004Assignee: Robert Bosch GmbHInventors: Matthias Henschel, Martin Heyder

Patent number: 6506034Abstract: A fluid pump, in particular for the coolant and heating system of a motor vehicle, has a stator (21) of claw pole construction and a rotor (6), separated from the stator (21) by a pipe (11), which is immersed in the coolant and forms a vane wheel. The rotor (6) is disposed radially inside the stator (21).Type: GrantFiled: March 19, 2001Date of Patent: January 14, 2003Assignee: Robert Bosch GmbHInventors: Gerd Lentz, Christoph Heier, Matthias Henschel, Wolfgang Krauth

Patent number: 6487770Abstract: Rotors or stators of this kind are cut out from rolled sheet metal with a predominant magnetic direction and are stacked to form a rotor or stator lamination bundle. In order to largely compensate for a magnetic anisotropy of the rotor or stator lamination packet, when the sheet metal blanks are asymmetrical (A, B), they are cut out from the rolled sheet metal rotated in relation to one another with regard to the predominant magnetic direction. The process according to the invention can be used for electric machine rotors or stators comprised of sheet metal blanks.Type: GrantFiled: February 21, 2001Date of Patent: December 3, 2002Assignee: Robert Bosch GmbHInventors: Christof Bernauer, Matthias Henschel
