A valve gear arrangement for load change valves of internal combustion
engines has an intermediate element that is pivoted on a lever in the
cylinder head, to activate the load change valves. The intermediate
element engages a cam of a camshaft and has fork-shaped parallel guides
on guide cylinders, over the center axis of which a guide groove in the
shape of a circular ring segment extends. A roller axle of a roller that
engages the cam is displaceably guided in the guide groove. There are
springs supported on the roller axle that force the roller axle against
an adjustable guide element, counter to the acting forces, when it passes
through a plateau region of the cam, and lies against the plateau region.
