Einrichtung zur Betätigung von Ventilen an einer Kolbenmaschine mit veränderbarem Ventilhub, insbesondere einer Kolbenbrennkraftmaschine

摘要

The invention relates to means for the actuation of valves on a reciprocating engine with a variable valve lift, in particular a reciprocating internal combustion engine, with at least one camshaft (1). Each cam (2) acts on a lever arrangement (3) which actuates at least one valve, has at least one pivotably mounted lever (4, 5; 30) and is connected on one side to the cam (2) and on the other to the valve to be actuated. The lever arrangement (4, 5) has adjustment means (13, 17) which can be used to set an idle stroke in relation to the valve.
