Patent number: 6158485Abstract: In the case of a filling device for a motor vehicle fuel tank, a distributing element extends from a filling nozzle to an anti-surge tower of the motor vehicle. When there is a low volume flow of fuel in the filling nozzle, the distributing element supplies all of the fuel to the anti-surge tower. When there is a large volume flow, the greater part of the fuel passes directly into the fuel tank. It is thereby ensured that during an initial filling or emergency filling with a jerrycan, virtually all of the fuel passes into the anti-surge tower.Type: GrantFiled: August 9, 1999Date of Patent: December 12, 2000Assignee: Mannesmann VDO AGInventors: Knut Meyer, Peter Andreas Low, Thomas Zapp, Christian Kochsmeier

Patent number: 6148977Abstract: Known free-wheel clutches are directionally operated clutches, which permit a shaft (12) and a hub (16) to carry each other along in one relative direction of rotation, for example by means of frictional connection. From time to time it is desired, on the one hand, to permit free-wheeling in both directions and, on the other hand, for example when a secondary drive is engaged, to obtain a frictional connection optionally in one relative direction of rotation. This is achieved in that, in the rest position, the clamping elements (28) have a frictional connection to the hub (16), and, with a contact face (36) interact with a fixed element (18). Only when the hub (16) begins a rotational movement is it possible for the clamping elements (28) to jam in a first locked position or a second locked position which acts in the opposite direction. The free-wheel clutch (10) can be used, for example, for coupling an electric servomotor to a steering column of a motor vehicle.Type: GrantFiled: August 5, 1999Date of Patent: November 21, 2000Assignee: Mannesmann VDO AGInventor: Nouhad Bachnak

Patent number: 6150811Abstract: A magnetic field sensor consists of a cylinder (2) with a core of premagnetized amorphous ferromagnetic metal. The inductance of the coil (2) is controlled by earth magnetic field H.sub.E and forms part of an L.C. oscillator (1). An adjusting device is provided to smooth out fluctuations from a target value in the oscillator frequency caused by the action of the field H.sub.E on the oscillator coil (2). This is done by allowing another adjustable magnetic field to influence the inductance (2) of the oscillator (1): the adjustable magnetic field is generated by a second coil (3) in the form of a compensating coil and the current flux (1) through the second coil (3) is controlled by the adjusting device in such a way that the magnetic field generated by the second coil (3) compensates for the action of the field H.sub.Type: GrantFiled: April 18, 1998Date of Patent: November 21, 2000Assignee: Mannesmann VDO AGInventors: Thomas Grill, Helmut Bacic, Martin Gruler, Oliver Springmann

Patent number: 6144927Abstract: A data-transmission device has a pulse generator (1) and a monitoring unit (20) for use in a vehicle. A signal generated by the sensor (2) is transmitted from the pulse generator (1) to the monitoring unit (20) by a signal line (9) and also, when requested by the monitoring unit, is transmitted in encrypted form along a data line (19). The signal generated by the pulse generator (1) is first stored in an intermediate store. Before transmission, the contents of this store are encrypted. On arrival in the monitoring unit, the encrypted signal is compared with the signal previously transmitted in the usual way and recorded there. This is a security check which reveals any manipulations which have been made during transmission.Type: GrantFiled: September 14, 1998Date of Patent: November 7, 2000Assignee: Mannesmann VDO AGInventors: Thomas Grill, Martin Gruler, Ludwig Buscher, Helmut Bacic, Norbert Lais, Hartmut Schultze, Josef Wangler

Patent number: 6142523Abstract: A profile steering spindle of a motor vehicle has a telescopic profile piece, which can be displaced in the axial direction by an adjusting tube, and into which project a first profile piece close to the steering wheel and a second profile piece remote from the steering wheel, intended for retaining a steering wheel. During axial displacements, the second profile piece remote from the steering wheel can be displaced relative to the telescopic profile piece by an adjusting tube without expenditure of force. The first profile piece close to the steering wheel is connected to the telescopic profile piece by means of bending lugs. If the driver of the motor vehicle strikes the steering wheel, the bending lugs are held by the telescopic profile piece, and the first profile piece close to the steering wheel is torn. The kinetic energy is thereby absorbed.Type: GrantFiled: December 17, 1998Date of Patent: November 7, 2000Assignee: Mannesmann VDO AGInventors: Peter Bathis, Raimund Grabis

Patent number: 6133546Abstract: Only a small useful quantity of washing water as close as possible to the spray nozzles of the windshield wiper system is heated. As a result of corresponding miniaturization, the heating time can be reduced to 5 to 10 seconds. A sufficient cleaning effect can be achieved in most cases by hot water after the windshield spray system is actuated two or three times. Additional cleaning can be carried out either by rinsing with colder or cold water or by repeating after 10 to 20 seconds. The water is heated via an instant heating element which, with a content of, for example, 10 to 50 cm.sup.3, can be installed even in a secondary chamber. Some of the heat energy is therefore stored in a larger thermal reserve tank of, for example, 1 dl.Type: GrantFiled: April 12, 1999Date of Patent: October 17, 2000Assignees: Mannesmann VDO AG, Rashpal BainsInventor: Rashpal Bains
