Patent number: 6078107Abstract: A process and a device for shutting off of a motor vehicle heating device in which a liquid heat exchange medium is heated by a heating device and is delivered to a heat exchanger of the heating device by means of a circulating pump driven by an electric motor. To prevent damage to the heating device or the circulating pump when the heat exchange medium circuit is not adequately filled with liquid heat exchange medium or in the case of poor venting, a value which at least indirectly indicates the power consumption of the electric motor is sent to a control device as a signal indicative of the existence of a delivery fault associated with the circulating pump.Type: GrantFiled: October 16, 1998Date of Patent: June 20, 2000Assignee: Webasto Thermosysteme GmbHInventors: Gunter Kahnau, Helmut Nigst

Patent number: 5797648Abstract: A roof hatch, particularly to a roof hatch intended for vehicle roofs. The roof hatch has a cover, which, for exposing a roof opening defined by a frame in a fixed roof surface, is alternately, or also, simultaneously, tiltable at two opposite sides. In order to facilitate a low-friction and low-loss actuation with minor force, the push rods actuating the extension devices, in accordance with the invention, are pivotally supported with one end, and with their other ends are guided in cam surfaces of a driven cam disk which is centrally supported on the inner side of the cover, and are additionally guided in guideways fixed to the cover, which essentially have circular shape.Type: GrantFiled: April 1, 1996Date of Patent: August 25, 1998Assignee: Webasto Thermosysteme GmbHInventors: Gunnar Fiegel, Ulf Plettrichs, Alexander Walter, Thomas Schroferl, Hossein Soltanmoradi

Patent number: 5788150Abstract: A motor vehicle heating device with a burner which has a combustion chamber which is coaxially surrounded, at least in part, by a heat exchanger which has a closed end at an end of the combustion chamber opposite that at which the burner is located, and which has an annular space, which is defined between an outer wall and inner wall, through which a liquid heat transfer agent flows. The heat exchanger is made of a one-piece construction, so that the end of the heat exchanger joins its outer and inner walls, and at the same time, its inside faces the combustion chamber. By this construction, the liquid-carrying part is essentially formed by a single part, so that no integrity problems can occur between the liquid-carrying annular space and the exhaust gas-carrying interior of the heating device and production costs are reduced.Type: GrantFiled: March 18, 1996Date of Patent: August 4, 1998Assignee: Webasto Thermosysteme GmbHInventor: Michael Bittmann

Patent number: 5738506Abstract: The invention relates to motor vehicle heating device with a burner, to which combustion air is supplied via combustion air inlet openings by means of a fan and to which furthermore fuel gas is supplied via a fuel gas supply line, combustion air and fuel gas entering on the intake side of the fan. It is provided according to the invention for a simpler structure and good mixing of the fuel gas/combustion air mixture that entry of fuel gas is controlled by means of a valve or switch controlled by the negative pressure of the fan. Fuel gas is supplied in doing so, preferably, with a negative pressure which is less than atmospheric pressure. For especially simple control of gas supply, there is a membrane which causes the fuel gas supply line to close when the fan stops.Type: GrantFiled: October 21, 1996Date of Patent: April 14, 1998Assignees: Webasto Thermosysteme GmbH, Webasto Thermosystems Ltd.Inventors: Ernst Mosig, Gunter Kahnau, Shahrzad Rahbar, Helmut Schmitter, Chris Kulaga, Frank David Williamson
