Force control for lift valve of internal combustion engine, has clamping device implementing fast switching, so that lifting movement of open and/or closed tappet is decouplable based on angle adjustment of cam shaft from lift valve
摘要
<p>The control (1) has a cam shaft with open and closed tappets, where the closed tappet supports the open tappet in a longitudinal direction of an internal combustion engine (2) and operates a tapped surface for the open tappet in the open direction. The closed tappet operates in the closed direction during the interconnection of a rocker arm. A clamping device (30) implements fast switching in such a manner that the lifting movement of the open tappet and/or the closed tappet is decouplable based on the angle adjustment of cam shaft from the lift valve. The clamping device is arranged in the valve lifter and cooperates with the shaft end of the lift valve.</p>
