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 () drives by means of a push rod () via a hydraulic valve clearance adjustment element () a rocker lever (), which has a curve contour (), which runs on a roller () of an intermediate lever (), which is moveable by means of two rollers (), which are arranged on one axis, in slotted links (), which are connected in a fixed manner with a cylinder head, whereby the intermediate lever () supports with one contour at an adjustment bar (), which is conducted in a housing, and rolls with a work curve () on a roller () of a cam follower (), and whereby the cam follower () acts with engagement areas, which are provided bottom-sided, respectively, on a hydraulic adjustment element () and a valve () of a combustion engine.
