ABSTRACT:
A compact, stress-orientated valve control arrangement for an internal combustion engine which is favorable from the production point of view and uses as many identical parts as possible includes a plurality of lift valves for each cylinder and pivoted valve activating levers with hydraulic supporting elements allocated to the latter, in which the geometric arrangement of the pivoted levers for the cylinder is such that the longitudinal axes of the supporting elements extend on the same side relative to the longitudinal axes of the camshafts and extend past the corresponding camshaft axis.
