Abstract
The invention provides a variable valve gear for internal-combustion engines, in which a control cam of a camshaft acts by way of an interconnected roller onto a swivellable or tiltable valve lever for actuating an upper valve, for achieving a continuous valve timing and stroke adjustment of the upper valve. In the case of a minimal stroke, the roller, by way of an adjustably controlled adjusting lever is positioned in the outer end area of this valve lever and is guided to be swivellable transversely to the cam lift of the control cam.
