  • 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

  • Variable valve lift control system for a combustion engine with underneath camshaft
    Patent number: 7712442
    Abstract: In order to produce a variable valve lift control system for a combustion engine with underneath camshaft for the adjustment of a valve lift and an opening time of at least one inlet valve and/or outlet valve, load-dependently and rotation speed dependently as well as for the switch-off of individual cylinders of an internal combustion engine, it is suggested that an underneath camshaft (1) drives by means of a push rod (3) via a hydraulic valve clearance adjustment element (2) a rocker lever (4), which has a curve contour (14), which runs on a roller (13) of an intermediate lever (9), which is moveable by means of two rollers (15), which are arranged on one axis, in slotted links (10), which are connected in a fixed manner with a cylinder head, whereby the intermediate lever (9) supports with one contour at an adjustment bar (11), which is conducted in a housing, and rolls with a work curve (16) on a roller (8) of a cam follower (7), and whereby the cam follower (7) acts with engagement areas, which are prov
