ABSTRACT:
An arrangement for controlling a deactivatable valve in an internal combustion engine includes a locking member which is displaceable between valve-locking and valve-release positions in a coupling element consisting of a rocker arm connecting the camshaft with the valve. In the deactivated state, the rocker arm is movable with respect to the valve and the valve return spring acts as a restoring spring acting through a spring plate which is displaceable relative to the valve.
