Abstract: A variable valve drive for a lifting valve, such as a charge-exchange valve of an internal combustion engine, that is periodically movable between closed and open positions indirectly by way of a cam via a rocker lever. The variable valve drive includes a switchable rocker lever arrangement for the actuation of the lifting valve, having a transmission rocker lever and a valve rocker lever which are mounted pivotably on different rocker lever axles parallel to the camshaft axis. The valve rocker lever, is in operative contact with the lifting valve at a first end, and has a roller, at a second end. The transmission rocker lever, is in engagement with a cam of the camshaft and, is operatively connected to the roller of the valve rocker lever.

Abstract: A variable valve train for a gas exchange lifting valve of an internal combustion engine. The valve can be moved between open and closed positions periodically by way of a cam via a rocker arm. The variable valve train includes a camshaft having at least first and second cams which are arranged offset in the longitudinal direction of the camshaft. The first and second cams having cam contours. The valve train includes a rocker arm mounted which pivots about a rocker arm axis and is assigned to the at least one first cam via a pressure roller at its camshaft-side end and is connected to at least one lifting valve at its valve-side end, and a roller lever which is assigned to the at least one second cam at its camshaft-side end and is articulated at its other end on the rocker arm and pivots about the rocker arm axis.

Abstract: The present disclosure relates to a variable valve drive for a lifting valve, in particular for a charge-exchange valve of an internal combustion engine, which is periodically movable between a closed position and an open position indirectly by way of a cam via a rocker lever. The variable valve drive includes a switchable rocker lever arrangement for the actuation of the lifting valve, having a transmission rocker lever and a valve rocker lever which are mounted pivotably on different rocker lever axles which are each parallel to the camshaft axis.
