  • Variable valve lift device for the lift adjustment of gas-exchange valves of an internal combustion engine
    Patent number: 7895981
    Abstract: In order to produce a variable valve lift device for the lift adjustment of the gas-exchange valves of an internal combustion engine, by means of which with adjustment forces and holding forces, independently from whether said holding forces and adjustment forces are applied mechanically, hydraulically or electrically, with an adjustment of the valve lift being as cost-effective as possible, and with maximum accuracy of the adjustment or control of the valve lift to be taken between the individual cylinders of a multi-cylinder internal combustion engine, and, moreover, the adjustment possibility of the valve lift of the valves of an internal combustion engine with several cylinders is obtained within smallest tolerances, it is suggested that a valve lift device (1) has a rotatable eccentric shaft (3), which consists of several eccentrics (4, 5) and whereby all possible contours of the eccentrics (4, 5) are positioned within a circle, which is formed by means of the external diameters of a bearing (6, 7) of th

  • Control device for at least one consumer, such as a camshaft adjuster, automatic transmission and the like, of motor vehicles
    Patent number: 7047931
    Abstract: A control device for at least one consumer of a motor vehicle, having an engine and at least one pump for supplying a medium via at least one pressure line to the at least one consumer, is configured to supply the medium to the at least one consumer before the engine is started. The pump can be driven by an electric motor or by the engine of the motor vehicle or alternatingly by the electric motor and the engine.
